Edit a Filter in its node and resize EQ and Filter nodes (#385)
A Filter sounds like one band of the Parametric EQ, but it keeps what the EQ cannot: linked numbers, the all-pass and +-40 dB. So it stays a node of its own and gets the EQ's editor with itself as the one band. The editors also stop running out of their room: what does not fit is left out instead of being cut. - The curve of the EQ is now BandCurve with a host the EQ and the Filter both fill. CurvePanel holds what their panels share. - FilterPanel shows the Filter as one band. A drag of its handle sets frequency and gain as one undo step. A number fed by a link is greyed out and the drag leaves it alone. - A double-click on the Filter's title opens the same in a tab of its own. Delete there does nothing, the node stays. - The Filter is tapped like the EQ, so its node and its tab draw the spectrum of what passes it. A tap is two gain nodes per voice, the analysers are made only while someone listens. - EqFace and FilterFace are one CurveFace now, given the panel. - EQ and Filter nodes have a corner to resize them, drawn like the floating window's. The size is saved on the node as `size`, each drag is one undo step, the least is 240 x 120. - In the node the help line is gone. The row of numbers comes in only once the curve keeps 120 px of height. A group of the row that does not fit is not drawn, the one on the right first. - A frequency or dB label that would run into the one before it is left out. - The all-pass is drawn flat. The curve's maths takes every shape a Filter has. Found on the way: - The instrument presets set nodes 240 apart. A Filter with its editor is about 700 wide and covered the Bitcrusher, so a Filter now takes four columns. Tests: - Unit: 8 new (filter band, resize command and save, fitting rules), stage lists with a Filter now hold its taps - e2e 34 (atx): ALL PASSED, 130 checks (4 new) - Gate (atx): CHECK EXIT 0, 284 files, 4367 tests Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> |

Edit a Parametric EQ in its node, let the wheel only zoom graphs (#381)
The small curve below the EQ node's rows (#375) only showed the bands. Like the Compressor since #380, the node now shows the editor of its tab between its inputs and its output, and is worked right there. A double-click on the node still opens the same editor in a tab. Two wishes for the nodes with a panel came on top and share the same files, so they are in this commit as well: the numbers below the Compressor's knobs read as plain labels (#382), and the wheel over a node zooms the graph instead of turning a value (#383). #381, the EQ in its node: - EqPanel holds the curve, the band's numbers and the help line, taken out of EqEditor. The tab puts its one panel under a header, each EQ node has a panel of its own at 720 x 360 (EqFace). - A press on the curve neither picks nor moves the node. A double-click on the curve adds a band, one on the title or the edge opens the tab. - In the node a press on the Type or Slope button stays with the button, so the node is not picked or moved. - The spectrum runs in the node while it is in the picture. The tab lets go of the tap once, like the Compressor's, and Editor.tick lets every unseen tab and graph go before any seen one listens. - The count of bands moved from the tab's header into the band row, so the node shows it as well. - The node picture of #375 is gone with its only user: NodePicture, EQ_PICTURE and NodeView's drawing of it. #382, the numbers below the Compressor's knobs in its node: - A Knob with typed: false shows its number as a centred Label without a box, in the panel's ink. The ratio reads 4:1 (ratioText). - The label is as high as its text and sits up in the dial's open bottom, right under the ends of the scale. - Label takes a colour of its own. #383, the wheel in a graph: - GraphCanvas takes the wheel on the way down and stops it there. It zooms over a node too, and no knob or curve in a node sees it. - The tabs keep their wheel: a knob's step, a band's Q and the zoom of the EQ's dB. Found on the way: - A Menu opened below a button in the zoomed graph would have been placed by the button's own height. openBelow now takes the bottom edge as drawn. - The band row did not lay out its labels after a text change when its own size stayed. In the tab a later resize hid it, in the node "Band 1" and the count were missing. The row now lays out itself. - Handle and point positions for the checks were unscaled. They now go through toGlobal and hold at the graph's zoom. Tests: - Unit parametric-eq: 16 tests. The #375 tests now check eqCurvePoints and eqRangeOf directly. compressor-view: ratioText. - e2e 34 (atx): ALL PASSED, 125 checks (3 new: the EQ panel and its ports, editing in the node, the spectrum in the node with the tab open). The Compressor node's check reads its numbers as labels and 8:1. Both node checks now expect the wheel to zoom the graph and leave the ratio, the Q and the dB zoom alone. - The unseen-tab check now leaves for the Scene tab, since the node in the graph listens to the same tap. - Counter-check: the tab letting go of the tap every unseen frame stalls the node's spectrum with the tab open (1 frame against 22, probe on stein2). - Gate (atx): CHECK EXIT 0, 283 files, 4357 tests.

Fit the Compressor's tab to any size, make auto-gain a switch (#378)
Two things came up on the new tab. Floated and sized down, it spilled its knobs out of its window, and sized up it left the window empty. Auto-gain lifted far too much: it brought 0 dB back to 0 dB, which at -40 dB, 4:1 and knee 6 is +28.1 dB, so a sound at -24 dB came out at -6 dB. And as a knob from 0 to 1 it blended between makeup and auto-gain, so at 1 the makeup knob did nothing. Layout: - The knobs stay on the bottom line, centred, with the help line above them. - The levels fill the height left above. The curve is a square at their right, centred up and down. It grows with the tab from 180 to 360 px and takes no more than 40 % of its width (picturesLayout). - A floated window cannot be sized below what its pane needs. A pane says so in its minWidth and minHeight, and the Compressor's is every knob and the smallest pictures. Other panes keep 320 x 200. - A pane put into an open window that is too small grows the window. Auto-gain, as decided in #378: - A Compressor's auto-gain gives back what it takes from a sound at -18 dB, so that one comes out as loud as it went in. At the numbers above that is +14.6 dB. - Auto-gain is a switch on the Compressor, the Limiter and the Saturation alike, a setting and no longer an input. The makeup or output is added on top of it instead of being blended with it. - A project from before reads a number as on above 0. Nodes never set keep their defaults: off on the Compressor, on on the other two. - The tab shows the switch at the right of the knobs, with the dB it gives below it. With it on, the curve has a line at -18 dB from the curve up to the diagonal. - Every level reading keeps the gain of its time. Before, the whole picture was read by the current makeup, so after a change the tinting of the last seconds was wrong or missing. Findings: - My first e2e run of the layout clicked Dock where it was before the window was sized up, so the window stayed open and the next check went red. The check reads the button again. Tests: - Gate (melektaus-atx): 282 files, 4344 tests (6 new) - e2e 34 (melektaus-atx): ALL PASSED, 118 checks (2 new) - Offline in Chrome: a sine at -18 dB through -24 dB and 4:1 came out at -17.92 dB with auto-gain on and -22.42 dB with it off. - Counter-checks: the curve set at the top instead of the middle, and every reading read at a gain of 0, each fail exactly their test. - Looked at the window in screenshots: at its least every knob and the switch show. At 1280 x 797 the levels fill the height, the curve is centred at the right and the knobs are at the bottom. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> |

Edit a Compressor in a tab of its own, with knobs and levels (#378)
A Compressor had only its number rows in the node. Its numbers are
easier to set by feel on a dial, and what it does is easier to judge
when the level going in and the level going out are seen side by side.
- Knob is a new widget in the toolkit: a slider bent into a circle,
its name above and a number field below. A drag up or down turns
it, Shift a tenth as far, a notch of the wheel a fiftieth of the
turn, a double-click sets the default, the number takes a typed
value. A taper gives the low end more of the turn.
- The Compressor's tab opens on a double-click, one per node, like
the Parametric EQ's. It has a knob for each of the seven numbers,
greyed while its input is linked.
- Its curve shows level in to level out from -60 to 0 dB. The point
where it bends sets the threshold, the end of the curve sets the
ratio that ends there.
- Its levels show the last 4 s on both sides of the node. Where it
takes more than 0.5 dB away, the stretch below the level coming in
is tinted. The makeup is left out of that.
- The Compressor is tapped like the EQ. SpectrumTaps listens to more
than one node at once and reads the loudest sample of the last
25 ms on each side.
- The node tabs share one map in the editor (nodeTabs), so a third
kind needs no new plumbing.
Findings:
- CI task 614 for

Decode a clip from a file of its own, not its whole sound (#349)
A clip was cut from its sound's file, so a game decoded the whole file for it and held it for as long as the page was open. A long recording played through a few short clips cost the recording. Every clip now has a copy of its cut as Opus, with Stream on or off, and a game decodes that instead. - StreamKeeper makes the copy of each clip whether its sound streams or not. Stream only decides whether a sound gets a copy of its own. - clipCopyTable says which cut decodes from which copy. The sound library loads the copy for a clip unless the whole file is decoded already. Then the clip is cut from that as before. - projectFiles decodes the whole file ahead only where something may play the sound itself: no clips, a clip without a fitting copy, or the sound's id anywhere in an asset that can name one. That last test walks the data, not the fields, so no place is missed. - A copy that cannot be had falls back to the whole file. A library that bakes keeps to the whole files, as the bake's fingerprint does. Tests: - Gate: CHECK EXIT 0, 280 files, 4319 tests (7 new: streams +4, sound-library +3). - e2e 34: ALL PASSED, 108 checks (2 new). With Stream off a fresh library decodes the ten-second reversed clip's copy and not the five-minute file. It is the cut made from the original to within 0.0091 a sample and 0.013 dB in any 20 ms. Once a node plays the sound itself, the whole file is decoded ahead again. - e2e 65: all passed with this change. - Counter-checks red as they should be: the library ignoring copies, the whole file always decoded ahead, clip copies only with Stream.

Stream long sounds from an Opus copy instead of decoding them (#349)
A sound was decoded whole as soon as the project opened, in the editor and in a released game: five minutes of stereo held some 115 MB for as long as the page was open. A sound with Stream on now plays from a copy as Opus in Ogg, fetched a piece at a time and decoded a few seconds ahead by WebCodecs, so a game holds a few megabytes for it. - The Stream switch is a row of the sound, off by default. The Sound tab suggests it from a minute on and says how far the copy has got. - StreamKeeper makes the copies in the browser, a moment after the last change, one at a time: the sound's own and one per clip of its cut, fades and Reverse baked in. A copy that is no longer wanted is taken off and deleted once the project is saved without it. - streamTable says which played names stream from which copy. A clip without a fitting copy, a Sample and a Reverb impulse stay decoded. A sound with Stream on is never decoded ahead. - The page fetches by Range and takes the whole file from a server that ignores it, as the CI's PHP server does. It keeps the bytes and the first two seconds decoded, the rest goes four seconds ahead. - A jump decodes 32 packets before the place first. Measured in Chrome, what follows is then the same to the bit as decoding from the start. With 4 packets it was 0.06 off. - The stream-player on the FX worklet reads the samples at the rate of the context along a Catmull-Rom curve. What comes late is silent and skipped once it is there, so a clip keeps its beat. - The opening stretch goes with the player as it is made. Sent by message it came a few milliseconds late, and 557 samples of the attack were lost. - Pitch on a streamed sound is a shifter after the player, as on a bus: the length stays and it is heard 42.7 ms late. - Bakes of patterns and songs (#340) always stream now. - The song timeline draws a streamed sound from its copy decoded at 8 kHz, keeping only the peaks. Tests: - Gate: CHECK EXIT 0, 280 files, 4312 tests (31 new: ogg +3, stream-queue 6, streams 11, streaming 6, sound-library +5). - e2e 34: ALL PASSED, 106 checks (7 new). Five minutes of mono, 4.8 MB as WAV, 3.6 MB as its copy: streamed the renderer grows by 5.8 MB, decoded by 69.6 MB. Offline at 48 kHz, start, loop seam and a reversed clip are the copy decoded whole to the sample (0). - Counter-checks red as they should be: no pre-roll, no catch-up of late samples at the end, no opening stretch, a streamed sound decoded ahead.

Bake a pattern or song to Opus, played in its place by a game (#340)
A pattern or song played by a game runs every note through the scheduler, the instruments and their FX, live. Bake works that out once, keeps it as a file on the asset, and Play pattern and Play song play the file instead, as one voice, for as long as nothing it is made of has changed. The tabs always play live. - Bake is an icon in the header of the Pattern and the Song tab, lit while the bake holds. A click bakes, cancels a bake that runs, or offers Bake again and Remove bake. The toolbar shows the progress. The info of the tab says "baked" or "bake outdated". - The bake holds everything up to the output of the pattern or song. The sound FX of the node, fx params, volume, fade in, bus, Master routing and stopping with a fade stay live. - A print of the worked-out plan decides whether it holds: notes and clips, tempo, length, loop, tracks, the build of each instrument for each note, sound FX, files, cuts and levels. A rename keeps it, an undo back to the baked state makes it hold again. - The file holds the straight run and then one more round of the loop as heard the second time, tails included. Looped, it plays to the loop end and then round that round, to the sample. Once, it fades out over its last 10 ms. Let ring fades it out over 0.3 s. - It is worked out by a second SoundLibrary on an OfflineAudioContext, its scheduler woken by suspends of the offline clock, and what reaches the master is taken. A worklet probe tells whether that was mono, so a mono bake goes on exactly as the notes did. - Opus in Ogg, 160 kbit/s stereo or 96 kbit/s mono, encoded with WebCodecs, the Ogg pages written by hand. Normalized to full scale, the peak kept and played back. - The file goes up into the sounds of the account as "[bake] name", which the sound picker leaves out. An old bake file is deleted once the project is saved without it. Only a bake that holds is loaded. - Ogg files are decoded at 48 kHz: resampled to 44.1 kHz, the loop of a bake lost a sample a round. - Baking and removing a bake are no undo steps, like the EQ's zoom. Findings: - Chrome's AudioEncoder refuses opus.format 'ogg' (NotSupportedError) but hands out the OpusHead with a pre-skip of 312 for 'opus'. - The Song tab's header is full at 1280 px: a captioned Bake pushed Fit off the tab. Hence the icon. Tests: - Unit: tests/core/ogg.test.ts (6), tests/core/bake.test.ts (16), four new in sound-library.test.ts, one in song-play.test.ts. One test cuts, reverses and fades a clip on a song's track: each change outdates the bake, each undo makes it hold again. - e2e 64 (melektaus-atx): ALL PASSED, 36 checks (6 new). Live and baked rendered offline differ by at most 0.06 dB over 114 windows of 20 ms, two loop ends among them. e2e 65 had no red check with the icon in its header. - Gate (melektaus-atx): CHECK EXIT 0, 277 files, 4281 tests. - Counter-checks: print without instrument builds, print taking the sound's file instead of the clip's cut, round taken from the first pass, bake voice without its looping source, Play pattern or Play song ignoring the bake: one unit test red each. Pre-skip set to 0: the e2e comparison 4.8 dB off, only that check red. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> |

Zoom the Parametric EQ's dB with the wheel, saved on its node (#376)
Close moves of a few dB were hard to set and to see on a curve that always spans -24 to +24 dB. The wheel on free space now zooms the dB the curve shows, and the node's small curve shows the same range. - The range is one of ±3, ±6, ±12, ±24 and ±48 dB, always the same either side of 0. Up zooms in. - It is saved on the node as `range`, so it is back after loading. Like the game scale (#226) it is no undo step. EditorState gets `setNodeView` for such a setting of a node. - The lines across the curve follow the range: every 1, 2, 3, 6 or 12 dB. A handle whose gain lies beyond the range stays on the edge, in sight and in reach. - The wheel over a handle still turns the band's Q. It no longer does so anywhere while a band is picked: after opening, a band nearly always is, and the zoom would be out of reach. - `EqArea` carries the range, so the tab and the node map dB alike. The spectrum keeps its own scale. Tests: - Unit parametric-eq: 16 green, 5 new (range in compile and save, node picture, wheel steps, grid lines, handle on the edge) - Counter-check: the node's picture without the saved range turns the new picture test red - e2e 34 (melektaus-atx): ALL PASSED, 99 checks, 1 new - Gate (melektaus-atx): CHECK EXIT 0, 275 files, 4252 tests Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> |

Draw the EQ's curve in its node and a spectrum behind it (#375, #374)
Both were asked for in #367 "for later". The node of a Parametric EQ now shows its curve in small, and its tab shows what passes the node while it is seen. #375, the curve in the node: - NodeDef has an optional `picture`: a height, and shapes made from the settings as plain point lists (guide, area, line). It is general, the Parametric EQ is its first user. - NodeView draws it in a box below the rows, again only when the box or the settings change. A drag in the EQ tab changes them, so the node follows it live. - Without a band the box stays, flat on its 0 dB line, so the node does not grow at the first band. - The axes of the curve, `eqCurvePoints` and `fillShapes` move from editor/soundfx/eqView to core/soundfx/parametricEq. Tab and node draw the sum from the same function. #374, the spectrum: - A node marked `tapped` gets a `tap` stage in front of its own stages and one behind them when compiled, in a sound FX and in an instrument alike. Its id is asset and node, since a copied asset keeps its node ids. - A tap is a gain of 1. SpectrumTaps (new, viewport/spectrum.ts) holds the tap of every voice and bus while it plays. - While the EQ tab is seen, in the tab row or in a window, the taps of that node feed one analyser per side (8192 points). Nothing is made before a tap of the node plays, so no AudioContext is opened early. - The tab draws both behind the curve, on a scale of 0 to -96 dBFS: the sound coming in faint and grey, the sound going on in the colour of a sound port. The analyser smooths it, and once the sound has gone the sum still hands it silence, so it falls away. - Once the tab is not seen, Editor.tick lets the analysers go, like the meters of the Song tab. - A tap does nothing to the sound, so `stats().last.stages` leaves it out, and a bypassed EQ keeps its taps. Decided on my own: - Every sound passing the node counts: Play of the sound FX tab, an instrument's keys, a song, a run. The issue proposed that. - The spectrum has no labels of its own. Its scale is in the wiki. Tests: Gate (melektaus-atx) 275 files, 4247 tests (11 new), EXIT 0 e2e 34 (melektaus-atx) ALL PASSED, 98 checks (2 new), twice Counter-checks, each put back by copy and compared with cmp: - The node's curve drawn without its bands: 2 unit tests fail. - The spectrum without the loudest bin between two points: 1 fails. - SpectrumTaps.stop leaving the taps linked: 1 fails. - Taps that never feed the analyser: e2e 34 fails in exactly the spectrum check (frames 0). Run in the container only. The screenshots of the second run were looked at: the blip as one peak behind the curve, and the dip at 4 kHz in the node.

Shape a sound with a Parametric EQ and its own curve editor (#367)
A sound FX or an instrument had a 5-Band-EQ with fixed bands and a Filter with one band. The Parametric EQ holds up to ten bands of any type, and a double-click on the node opens an editor that draws the curve they make together. - The bands are a list on the node (`bands`): type, frequency, gain, Q and slope. A hand-edited project is held to the editor's ranges and to ten bands. - Each band compiles to the existing `pass` stage, so the audio core is unchanged. A peak or a shelf at 0 dB is left out. - The curve is worked out in `parametricEq.ts` with the biquad formulas of the Web Audio spec, so the editor draws what is heard. - The editor is a window that floats over the editor without a backdrop, so the tab's Play stays usable. A double-click adds a peak, a drag moves a band, the wheel turns its Q, a right-click removes it. Fields below the curve set the picked band. It opens in the middle of the screen and moves by its title bar. - A drag or a scrub writes the node as a preview and makes one undo step on release. The panels hear of the preview once a frame, and the window lays itself out only when one of its texts changes. - The area under the curve is filled as one shape for each side of 0 dB. As a single shape it crossed itself and came apart. - The curve works out each band's coefficients once and adds the sum up from the bands. A drag took 295 ms of script time in a profile before and 64 ms after. Decided on my own: - Bands are added by a double-click, so a single click can let go of the picked band without adding one. - The cuts are labelled "Low cut" and "High cut" as in an EQ, not "High-pass" and "Low-pass" as on the Filter. - The bands have no input, so no parameter or Envelope moves them. Tests: - Unit parametric-eq (new) and soundfx: 69 green. Counter-probe with no stages emitted: the compile test red. Counter-probe with one fill shape: the fill test red. - e2e 34 (melektaus-atx): ALL PASSED, 96 checks (3 new). - Counter-probe e2e: no stages emitted, the playing check red. - Gate (melektaus-atx): CHECK EXIT 0, 274 files, 4230 tests.

Snap a new song to 1/16, and route new assets as the others (#365)
A new song snapped to whole bars, too coarse to lay out a beat. And a new or duplicated sound, instrument, pattern or song went to the master alone, so every one had to be linked into the buses by hand again. - A song without a grid of its own snaps to 1/16. The songs in the user's project have Bar written in and keep it. - A new or duplicated sound, instrument, pattern or song gets the links of the one whose targets most others of its type share, at their volume. On a tie the latest of them decides, so a single song decides for the next one. - Where nothing of its type is linked yet, it goes as most of all that plays, and where nothing is, to the master. A new bus still goes to the master alone. - Assets made at once are matched against what stood before, not against each other. A project from before the routing still opens with everything on the master. - The song tab has a gridAt hook. e2e 65 checks the new grid and sets Bar, which its checks go by. Tests: - Unit master-routing (1 new) and song (1 rewritten): 26 green. Counter checks (rule off, grid back to Bar) red. - e2e 65 (melektaus-atx): ALL PASSED, 58 checks (1 new). - Gate (melektaus-atx): CHECK EXIT 0, 273 files, 4226 tests.

Route sounds, songs and buses in one Master routing graph (#351)
A project bus could only go into one other bus, and a sound, an
instrument, a pattern or a song into exactly one bus. A shared reverb
needs a sound to go there in part and on dry at the same time. Instead
of a list of sends on every asset, the project gets one routing graph
like the routing of a song (#350), one level up.
- Menu -> Master routing opens a tab with one graph per project. It has
a node per sound, instrument, pattern, song and bus, named after its
asset, and one Master. Embedded assets have none, their song routes
them.
- The nodes follow the assets. Every edit settles the routing in the
same undo step (KeepRoutingCommand), so an undone delete brings the
links of its asset back. A new asset gets a node and a link to the
master. What went only into a deleted bus goes to the master.
- New nodes start in three columns: what plays, the buses, and the
master a row above, so no link into it runs behind a bus.
- Links are sends: -60 to +12 dB, and a Mode on links out of a bus or a
song. Out of a sound, an instrument or a pattern a link always takes
the sound after its volume and FX. Loops are refused.
- A node without a link is silent and says "Goes nowhere".
- The rows Bus and Into are gone. Play nodes with a picked bus still
overrule the routing.
- A click on a node shows its asset in the inspector, the Master shows
the master volume and sound FX. A double click opens the asset's tab.
- The graph lives in project.routing and is held to the assets when a
project is read, but nothing is added there. The editor adds the
nodes when it opens a project. An asset without a node plays on the
master, so old projects sound as before without a migration.
- In the mix an asset with one link at 0 dB goes straight into that bus.
A sound or instrument with more gets a bus of its own with the sends.
A pattern or song sends from the master of its playing, which is
where its Mode taps. Buses of the mix can have sends now too.
Found:
- The check "the scheduler plans a looped bar" in e2e 34 wobbles. It
failed in 2 of 5 runs here and in CI task 580 at

Pick a pattern's sign in one row, as a song's (#364)
A pattern had two rows for its meter, Beats per bar and Beat, while a song has had one row Sign since #363. Both now pick from the same list. - The list of signs and how a sign becomes a meter moved to time.ts. Song and pattern share it. - A pattern keeps its meter in `sign`. The fields `beats` and `beat` are gone, a sign that is not in the list counts as 4/4. - Create pattern in a song hands the song's sign to the new pattern. - The four patterns of cbbf160bb7e8 were moved to `sign` by hand (three 4/4, one 3/4). The other projects only had 4/4, which stays the default. Tests: - Unit pattern/embedded: 30 green (1 new, 2 rewritten), the counter-test reading `beats` again turns 2 red - e2e 64 + 65 (melektaus-atx): ALL PASSED, 85 checks - Gate (melektaus-atx): CHECK EXIT 0, 272 files, 4215 tests Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> |

Pick a song's sign in one row, and let its patterns keep theirs (#363)
A song had two rows for its meter, Beats per bar and Beat, and the patterns it kept to itself took both from it on every change. Their length is counted in bars, so a new sign cut or stretched them and their items. - The song has one row Sign with 1/2, 2/2, 3/2, 1/4 to 6/4 and 5/8 to 9/8, 4/4 by default. It is stored as `sign`. A value not in the list reads as 4/4. - An embedded pattern keeps its own tempo and meter, as a project pattern does. Its inspector shows Tempo, Beats per bar and Beat again and hides only Bus. - A pattern made in a song still starts with the song's tempo and sign, so its first bar fits the item it gets. - A copy (Embed a copy, a paste from another song) keeps its clock. `clockFollowers` and the follow step in `AssetPropertyCommand` are gone. - No load migration. The two songs of the user's project were moved from `beats`/`beat` to `sign` by hand. No other project had a song with a meter of its own. Tests: - Unit song + embedded + pattern: 44 green, 1 new, 4 rewritten. Counter-probes: a copy taking the song's clock and a sign outside the list both turn a test red. - e2e 65 (melektaus-atx): ALL PASSED, 57 checks (1 new: Sign picked from its list in the inspector). - Gate (melektaus-atx): CHECK EXIT 0, 272 files, 4214 tests. After it, `SIGNS` lost its `as const` and the cast went with it. Typecheck, lint and the 44 unit tests ran again, all green. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> |

Let solo win over the mute of the same track (#358)
A track with both M and S on stayed silent: the mute closed every send before solo was asked. Pressing S on a muted track is meant to hear it. - trackGates in routing.ts opens the sends of a soloed track even while it is muted. Its own items are heard as with solo alone. - A muted track that a soloed one goes through, or that goes into it, stays silent as before. Tests: - Unit song-routing and song: 28 green (1 new), a counter-check red Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> |

Let the places of a song share what it keeps to itself (#357)
With clips, one take serves many items: four items on the four clips of one take. The rule from #355 gave every further place its own copy of an embedded asset, so a cut made in the Sound tab reached one item only. Now the song, its tracks and its items share a sound, a pattern or a sound FX the song keeps. - settleEmbedded no longer copies within the song. An embedded asset stays as long as one place names it, and goes with the last one. - A paste from another song still gets a copy, but one copy for all the places naming the same asset, with its clip ids mapped. - The picks in a song offer what the song keeps, under a line after the project's assets: the Sound row of an item the song's sounds and their clips, the Pattern row its patterns, every sound FX pick its sound FX. - Make project asset and Embed a copy are unchanged. The project cbbf160bb7e8 was merged by hand afterwards: the items of Song 2 on three copies of Take 1 now play the same clips of the first one, and the copies are gone. Tests: - Unit embedded, sound-clips, own-fx and the song tests: 66 green, 3 counter-checks red as expected - e2e 65 on melektaus-atx: ALL PASSED, 52 checks - Gate on melektaus-atx: CHECK EXIT 0, 271 files, 4198 tests Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> |

Cut a sound into named clips, as a texture into frames (#357)
A sound could only be cut to one stretch, set on the asset itself. To
play two parts of one file, the file had to be imported twice. Now a
sound is always the whole file, and its clips are the stretches of it,
each with a name and a cut of its own.
- A clip is { id, name, props } on SoundAsset.clips. Its id shares the
generator with asset ids, so a sound field holds a sound or a clip,
as a texture field holds a texture or a frame.
- props are the cut: start, end, the fades and their curves, reverse.
Volume, loop, sound FX and bus stay on the sound for all its clips.
The cut rows left the sound's schema for CLIP_ROWS.
- findSound resolves either id. Play sound, the Sample of an
instrument, a Reverb impulse, song items, the scheduler and the test
sound of the Sound FX tab all go through it.
- Every sound field offers each sound followed by its clips, "Kick",
"Kick / Clip 1". A clip that is gone reads as "<id>?".
- The Sound tab has a strip under the ruler with the clips as bands.
A drag there makes a clip, a click picks one, beside the bands the
sound. Only the picked clip has handles. Reverse, fades and curves
in the header work on it and are greyed out without one.
- Whole file is gone from the header, as the user asked.
- Picking a clip is a selection of its own, like a frame. The
inspector shows its name, its cut rows and Delete clip. Delete
takes it away without asking, as with a frame. Ctrl+Z brings it
back.
- Copies get fresh clip ids: Duplicate, Embed a copy, a song
duplicated with its takes, and the copy a split or paste makes of
an embedded take. An item on a clip plays the same clip of its copy.
- A double-click on a song item playing a clip opens its sound with
the clip picked. The Sound row of an item on an embedded take
offers the take and its clips, which no list shows.
- A new take stays the whole sound. Clips are made by hand, as the
user decided.
- No migration in the code, as the user decided. The one project
with cut sounds was changed over by hand.
Deviation from the issue: deleting a used clip does not warn. A frame
does not warn either, and the issue had promised "like a frame".
Tests:
- Unit sound-clips (new): 11 green, 7 counter-checks each red
- Unit sounds, embedded: adjusted to clips, green
- e2e 34 (melektaus-atx): ALL PASSED, 90 checks (3 new, 12 rewritten)
- Counter-check in the browser: clips left out of the sound fields,
the picker check fails
- Gate (melektaus-atx): CHECK EXIT 0, 271 files, 4194 tests

Give a song, a track or an item a sound FX of its own (#355)
A sound FX for one place in a song had to be a project asset, which then stood in every picker. Now every pick of a sound FX in a song can make one the song keeps for that place alone, on top of the embedded assets of the first two parts. - Create sound FX sits at the end of the Sound FX row of the song, a track and an item, and of the menu of a track's FX button. It makes "Sound FX 1", 2, … per song with the Input wired to the Output, picks it and opens it. That is one undo step. - Embed a copy, while the place names a project FX, gives the place a copy under the same name. - While the place names its own, the menu shows it with the mark and offers Edit sound FX and Make project asset. - Picking anything else lets it go in the same undo step. For a track or an item `settleEmbedded` did that already. For the song's own row `AssetPropertyCommand` now settles the song after `fx`. - The mark `•` moved to the core. `assetRefLabel` puts it in front of an embedded asset, so the inspector rows show it like the timeline. - `FieldHandlers.moreChoices` lets a caller end a reference menu with entries of its own. `embeddedPatternName` is `embeddedName` with a base now. Tests: - Unit own-fx (new): 6 green, 6 counter-checks each red - Unit embedded and 80 neighbouring files: 1434 green - e2e 65 (melektaus-atx): ALL PASSED, 51 checks (2 new) - Gate (melektaus-atx): CHECK EXIT 0, 270 files, 4178 tests Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> |

Make a pattern right in a song with a right-click (#355)
A pattern for one song had to be made in the Assets panel first and dragged in, and then stood in every picker of the project. Now a right-click on an empty spot of a track makes one the song keeps to itself, on top of the embedded assets of the first part. - Create pattern lays an item from the grid line before the spot, a bar long, and opens the pattern in its tab. Pattern, item and name are one undo step. The name is "Pattern 1", 2, … per song. - It plays the instrument of the track's pattern item that starts last before the spot, else of the first one after it. An item's own pick counts before its pattern's. - An embedded pattern runs on the song's clock. It takes the tempo and the meter of the song, and a change on the song moves it along in the same undo step (`AssetPropertyCommand`). - Its rows Tempo, Beats per bar, Beat and Bus are hidden, as the song decides them. Length, grid, instrument and sound FX stay. - A copy that comes to a song (Embed a copy, a paste from another song) takes that song's clock. Made a project asset, it keeps the values it had. - `CreateAssetCommand` takes an owner. `embeddedCopy` takes the song now, not its id. - The cleanup of e2e 65 also takes what the song keeps. Tests: - Unit embedded: 18 green (5 new), 6 counter-checks each red - Unit take, song, pattern and the asset commands: green - e2e 65 (melektaus-atx): ALL PASSED, 49 checks (2 new) - Gate (melektaus-atx): CHECK EXIT 0, 269 files, 4172 tests Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> |

Keep a recorded take inside its song (#355)
A take used to land in the Assets panel as "Song – Take N", next to every other sound of the project. Now a song can keep a sound, a pattern or a sound FX to itself: an ordinary asset whose new field `owner` names the song. Everything that finds an asset by its id finds it, so playing, the tabs and the game need no change. Only the places that list assets leave it out. - `core/music/embedded.ts` holds the rules: which types can be embedded, `listedAssets`, the title "Song › Take 1", and the rows an embedded sound hides (Loop, Bus). - One user per embedded asset. `SetSongCommand` settles the song after every edit: a place naming an asset an earlier place claimed, or one of another song, gets a copy, and what nothing names any more goes in the same undo step. The outcome is worked out once, so a redo brings back the same copies. - A split, Ctrl+D and a paste get that for free. The clipboard keeps the embedded assets of the copied items, so a paste after a delete brings the take back. - Deleting a song deletes what it keeps. Duplicating it copies that and points the copy at the copies. A duplicate of an embedded asset is a project asset. - The item menu has Open, Make project asset and Embed a copy. - An embedded item carries a bullet in front of its name. The first pick was a diamond, which the gate's font test refused: the UI font has no glyph for it. - A take is "Take 1", 2, … numbered per song. With the song gone while it uploads, it becomes a project sound under a free name. - Left out of: the Assets panel, every asset picker, the sound FX menu of a track, the test sound of the Sound FX tab and the naming of new assets. Delete on an embedded asset only says where it lives. A ping lights up its song. - Loading drops an `owner` whose song is gone, the asset stays as a project asset. No migration: older projects have no owner. Tests: - Unit embedded (new): 13 green, 6 counter-checks each red - Unit take, song, song-edit, asset-fx, asset-ref, serialize and neighbours: 116 green - e2e 65 (melektaus-atx): ALL PASSED, 47 checks (1 new) - Counter-check e2e 65 (asset panel unfiltered): exactly that check red - Gate (melektaus-atx): CHECK EXIT 0, 269 files, 4167 tests Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> |

Give every sound FX effect a Bypass and a Wet (#354)
A node could only be taken out of a sound FX by unplugging it, and only six of them could be blended with the sound they get. Every effect now has both, in the sound FX graph and in the instrument graph alike. The Mix, the Input and the Output have neither. - Bypass is a checkbox setting. A bypassed node is left out when the graph is compiled, so it costs nothing and holds nothing back. The graph draws it faded, and its body says "Bypass: true". - Wet is a number input like the others. It can be a parameter, be moved by Set sound FX parameters and, where the node allows it for its other numbers, follow an Envelope. - A blend is a stage of its own (`wet`) around what the node adds. The sound as it came in is held back as far as the node is late, so a Compressor, a Limiter or a Vibrato do not comb it out. - The six nodes that had a Mix keep their key `mix` and only call it Wet. Saved values, parameters and edges stay as they were. - The Delay crossfades now: the sound alone at 0, the sound and its echoes in full at 0.5, the echoes alone at 1. Before, the sound was always in full and `mix` was the echoes. - The Pitch takes its semitones by Wet instead of blending, through a share `times` on the amount that an instrument binds as well. Findings: - A Delay saved before this sounds different. It sounds the same at half its old value. The two chip presets with a Delay (Echo Lead, Bell) are halved to keep their sound. - Project cbbf160bb7e8 has two Delays (mix 1 and 0.5). They are left as they are. Tests: - Unit: soundfx 65 (8 new), sound-library 107 (3 new), instrument 35 (1 new), envelope 13. Two delay tests and the filter ports test follow the new numbers. - Counter-checks: 8, each turns its test red. - e2e 34 (melektaus-atx): ALL PASSED, 83 checks (2 new). The ping-pong check at wet 0.25 measures what it did at mix 0.5. - Gate (melektaus-atx): CHECK EXIT 0, 268 files, 4154 tests. - After the gate the derived ports of a blend are asked for once instead of twice: typecheck, lint and the three unit files green again (113 tests).

Give sounds, instruments, patterns and songs a sound FX (#352)
A sound FX could only be picked where something was played: on a Play
node, a track or an item of a song. A sound that should always sound
through the same effect needed that pick everywhere it was used. Now
the asset says it once, and every place that plays it follows.
- New row Sound FX on a sound, an instrument, a pattern and a song,
right before Bus. A sound goes through it on every voice, an
instrument on every note after its graph, a pattern on all its
notes together and a song on its output.
- The fx input of Play sound, Play note, Play pattern and Play song
and the Sound FX of a song item now read "From the asset" while
empty. None is a pick of its own, stored as `#none` like `#master`.
A pick replaces the FX of the asset, it does not come on top.
- A pattern item's Instrument reads "From the asset" instead of None.
The meaning is unchanged.
- A double-click on a sound item opens the sound, as one on a pattern
item opens the pattern.
- The tabs play through the FX of their asset. The Pattern and Song
tab put it on a bus of their own between the output and the bus of
the asset. The keys of the Pattern tab play there too.
- Notes of a pattern or song go through the FX of their instrument.
Its chain is loaded with the other needs of the sequence.
Decided without asking:
- Old items and Play nodes with an empty fx now mean "From the
asset". No asset has an FX yet, so nothing sounds different.
- The label is "From the asset" as on Loop and Bus, not "From asset".
- A sound used as a Sample, as the impulse of a Reverb or as the test
sound of the Sound FX tab plays without its own FX.
Findings:
- In e2e, `__gm.inspectorField('Sound FX')` and `('Instrument')` find
the group of the Assets panel first. The check asks for the last
match.
Tests:
- Unit asset-fx (new): 8 green. Six counter-checks each turned red.
- Field lists of sound, pattern and song: Sound FX added.
- e2e 65 (melektaus-atx): ALL PASSED, 46 checks (3 new). Counter-check
without the FX bus of the tab: that check red.
- Gate (melektaus-atx): CHECK EXIT 0, 268 files, 4142 tests.
- Not checked: how it sounds, the Sound, Instrument and Pattern tab
in the browser.

Put a sound in a room, a hall or a cave with a Reverb node (#328)
A sound FX had no space around it. The Reverb node folds the sound with an impulse response: one it makes itself, or a sound asset as the answer of a real space. It works on a voice and on a bus. - Type: Room, Hall, Cave and Plate have fixed numbers. Custom shows Decay (up to 10 s), Damping and Pre-delay. Sound shows the pick of a sound asset and Pre-delay. The rows are derived ports, the sound pick an idle param, so they only appear for their type. - The made impulse response is seeded noise per side, 60 dB down at Decay, through a low-pass closing from 20 kHz toward 500 Hz as far as Damping says. It is made once per rate, decay and damping, the last 16 are kept. - A sound as impulse response: the sound FX compilers now get the project, so a node can turn a sound asset into its file. The build key holds that file, so a cut or swapped sound builds again. The instrument compiler does the same for a Reverb inside an instrument. - The library loads that file with the voice, a sequence or before a bus builds its chain. A missing file leaves the reverb silent. - Mix blends dry and reverb and is the only number that moves while the sound plays, as the issue said. The voice rings for pre-delay plus decay, or as long as its sound. - The open point from #325 about sends on project buses is #351, not part of this. Tests: - Unit reverb (new) 4, soundfx 57 (4 new), sound-library 104 (2 new), green. - Counter-checks, each turns one test red: the impulse file not loaded with the voice, the tail without the length of the sound. - e2e 34 (melektaus-atx): ALL PASSED, 81 checks (1 new). Chrome offline: silent during the pre-delay, 35.9 dB fall over 0.6 s of a 1 s decay (36 expected), the dry half at 0.25 for mix 0.5. A sound with one sample at 0.2 s gives the impulse back 0.25 s later and nowhere else. - Gate (melektaus-atx) over the end of this series #318 to #328: CHECK EXIT 0, 267 files, 4134 tests.

Swing the volume or the pitch with Tremolo and Vibrato (#320)
Alarms, sirens and wobbly retro sounds need a volume or a pitch that swings. Two new nodes do that, on a voice and on a bus alike. - Tremolo: Rate (0 to 20 Hz), Depth (0 to 100 %), Shape (Sine, Triangle, Square, Saw). The volume swings between full and 1 - depth. - Vibrato: Rate (0.5 to 20 Hz), Depth (0 to 4 semitones), Shape. The shape is the curve of the pitch, a Square jumps between two pitches. - As the issue decided: two nodes, phase 0 on the first sample of the voice, no fade-in time. Both run on the FX worklet, the classes are in lfo.ts and tested in Node. - Deviation from the issue text, as in the plan: the Vibrato is a delay that swings, not playbackRate. A bus has no playbackRate, and the sound keeps its length. - The delay swings around a center taken from the start values. The center counts as the latency of the node, so a voice starts that much earlier and a Mix and a bus make up for it. - Known limit, in the node text and the wiki: a depth turned up or a rate turned down after the start asks for a delay below 0. The lower half of the swing then flattens. Finding: the first e2e run was red at the edge of a window. The phase is summed up, so the square flips one sample later than 2400 steps of 10/48000 suggest. The check keeps 10 samples away from the edges. Tests: - Unit lfo (new) 5, soundfx 53 (2 new), sound-library 102 (1 new), green. - Counter-checks, each turns one test red: the swing turned over (up and down swapped), the start time not passed to the worklet. - e2e 34 (melektaus-atx): ALL PASSED, 80 checks (1 new). Chrome offline: Tremolo square silent before its voice, then 0.5 and 0 for 50 ms each. Vibrato square at 5 Hz, 1 semitone: 1059.5 Hz and 940.5 Hz. - The gate runs once on the last commit of this series. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> |

Warm up or distort a sound with a Saturation node (#323)
A sound FX had no way to bend a sound. The Saturation node pushes it into a curve, from warmth to a hard distortion, on a voice or a bus. - Eight types, each a fixed curve made once: Soft (tanh), Cubic, Hard clip, Tube, Fuzz, Foldback, Sine fold and Rectify. The issue asked for as many as useful. - Drive (0 to 48 dB) is a gain in front of the curve. The curve spans 256 times full scale, so the drive glides like any gain. - Output and Auto-gain blend as on the Compressor. Auto-gain brings a sine at -12 dBFS back to the RMS it came in with. - Tone is a low-pass after the curve, 1 kHz at 0 to 20 kHz at 1, as recommended in the plan. A 10 Hz high-pass takes out the DC the lopsided types make. - Mix blends with the dry sound. The 4x oversampling is 192 samples late in Chrome, so the dry way is held back as far. The node counts as late by that much for voices, Mixes and buses. - A test hook gives e2e the auto-gain at a drive. Tests: - Unit saturation (new) 5, soundfx 51 (2 new), sound-library 101 (1 new), green. - Counter-checks, each turns tests red: no hold-back of the dry way (1), the level without auto-gain (2). - e2e 34 (melektaus-atx): ALL PASSED, 79 checks (1 new). Chrome offline: 192 samples late at 48 and at 44.1 kHz. Half dry at 1125 Hz 0.00 dB. A sine at -12 dBFS driven 24 dB into Soft comes out at 0.00 dB with full auto-gain. - The gate runs once on the last commit of this series. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> |

Tame the loudness with a Compressor and a Limiter node (#326)
A sound FX could not control dynamics. A Compressor squeezes the loudness together, and a Limiter keeps every peak below a line. Both work on a voice and on a bus, where they tame everything at once. - Compressor: DynamicsCompressorNode with Threshold, Ratio, Knee, Attack and Release, then Makeup and Auto-gain from 0 to 1. After the node the sound gets (1 - w) * makeup + w * A dB. A is what the curve takes off at 0 dBFS. - The node adds 0.6 of A by itself, as the spec says. That gain is taken back out, so 0 really means no makeup. - The knee shape is left to the browser by the spec. dynamics.ts ports Chromium's curve. It gives the gain Chrome was measured to add at four settings to three places. - Limiter: a class on the FX worklet with Threshold, Ceiling, Release and Auto-gain. It looks 5 ms ahead: the smallest gain of the window ahead, averaged over the window, then a release. No sample passes the lower of threshold and ceiling. Auto-gain raises it toward the ceiling. - Deviation from the plan in the issue: the Limiter has a Threshold as well. Without it Auto-gain has nothing to measure against. - Latency is made up on voices now too. A voice starts as much earlier as its stages are late (Compressor 6 ms, Limiter 5 ms). The other way of a Mix and the other layers of a note are held back to the latest, and a bus counts it into its latency. - A voice with a Limiter counts as ringing, so the worklet is stopped only after what it still holds is out. Tests: - Unit dynamics (new) 8, soundfx 49 (3 new), sound-library 100 (4 new), green. - Counter-checks, each turns tests red: no look-ahead in the Limiter (3), no taking back of the node's gain (1), a voice not started earlier (1), no stage latency on a bus (1), no hold-back in a Mix (1). - e2e 34 (melektaus-atx): ALL PASSED, 78 checks (1 new). Chrome offline: Compressor 288 samples late, Limiter 240. Full scale through -12 dB 4:1 hard knee: +0.19 dB with full auto-gain, -8.81 dB without. A sine at 2 through the Limiter at -6 dB peaks at -6.00 dB, with auto-gain 1 at -1.00 dB. - The gate runs once on the last commit of this series.

Move a sound left or right with a Pan node (#319)
A sound FX had no way to place a sound in the stereo field. The new Pan node does that on a voice, a bus and a track alike. - One input, Pan from -1 (left) to 1 (right), 0 by default. Behind it is a StereoPannerNode. A typed-in 0 leaves the node out, a pan fed from a parameter stays at any value. - It moves with Set sound FX parameters, and an Envelope can move it in an instrument. - As the issue decided, no pan from the position in Play sound and no width control for stereo sounds. Finding: the issue and the plan said a stereo sound gets a balance. Web Audio pans stereo differently: the side it goes to stays and the other side moves over into it. The node description and the wiki say so, the e2e check measures it. Tests: - Unit soundfx 46 (1 new), sound-library 97 (1 new), green. - Counter-check: a pan from a parameter at 0 left out, 1 test red. - e2e 34 (melektaus-atx): ALL PASSED, 77 checks (1 new). Chrome offline, a mono sine at 0.5 gives 0.5 / 0 at -1 and 0.354 / 0.354 at 0. A stereo one at 0.5 panned 0.5 gives 0.354 / 0.854. - The gate runs once on the last commit of this series.

Shape a sound with every filter type, a Q and a slope (#318)
The Filter node from #335 only knew low-pass, high-pass and band-pass and had a Resonance from 0 to 1. It now has every type Web Audio offers, a Q as a plain factor and a slope up to 48 dB per octave. - Types: low-pass, high-pass, band-pass, notch, low shelf, high shelf, peaking and all-pass. The cutoff row is now labelled Frequency, its key stays `cutoff`. - Q from 0.1 to 30, 0.707 by default, replaces Resonance. Web Audio takes the Q of a low- or high-pass in dB, so it is converted when the voice is wired. No project used the node. - Gain in dB is an input only for the shelves and the peak. It is a derived port, so the sound FX compiler now resolves derived ports. - Slope 12, 24 or 48 dB/oct runs 1, 2 or 4 filters in a row. They share one cutoff carried by a ConstantSource, only the last has the Q. Shelves, peak and all-pass hide the row. - The Chip Presets get the Q their resonance gave before. Mutate moves Q in octaves and gain by up to a dB. - bindStage in the instrument compiler binds every amount of a stage generically, so new stages need no case of their own there. Finding: FLAT_Q was in dB and the delay damping used it. It is a factor now, the damping takes it through passQ and is unchanged. Tests: - Unit envelope 13, sound-library 96 (2 new), chip-presets 14, soundfx 45, all green. - Counter-checks: the Q on every filter in a row, the gain row for every type. Each turns one test red. - e2e 34 (melektaus-atx): ALL PASSED, 76 checks (1 new). Chrome offline, 2 kHz through a low-pass at 1 kHz: -12.37 dB at 12 dB/oct, -49.5 dB at 48. A +6 dB peak gives 6.00 dB, a notch -124 dB. - The gate runs once on the last commit of this series. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> |

Route the tracks of a song through a graph (#350)
Every track of a song went straight into its output. Now the Song tab has a second view, Routing: a graph with a node per track and one Output, the links between them sends. A track can go into other tracks, into several at once, and a link has its own volume and the point of the track it taps. - The song asset has a graph like an instrument (SongTrack, SongOutput). heldSongGraph keeps it in step with the tracks on load and in SetSongCommand: a node per track named after it, one output, a new track and every track of an old song linked to the output. Links of gone tracks, doubled links and links closing a loop are dropped. - A link carries an optional send (volume in dB, tap). The inspector shows Volume and Mode for a picked link of a song: Post volume (Post pan), Pre volume (Post FX), Pre volume (Pre FX). SetSendCommand. - NodeDef has two new flags. `fixed` nodes are never added or deleted by hand. Links between `acyclic` nodes may not close a loop, checked in canConnect, dropTargetPort and ConnectCommand. - songBuses gives each track its sends instead of one `into`, and a bus `song:<song>:<track>:#items` for its own items. That bus is what solo closes on a track that only passes a soloed one on. - Mute and solo now act on the sends (trackGates). A muted track passes nothing on, on any tap. A soloed track is heard with what goes into it, through the tracks it goes through, their own items silent. Only sends on a way through a soloed track stay open, so a track going into it and into the output is heard through it only. - SoundLibrary: a bus has either `into` or sends. Each send is tap, delay, level, target. busLatency takes the latest way (arrivalOf), and each send is held back so all ways of a track arrive together (sendDelays). Taps are wired again whenever a chain comes or goes. - The Song tab has Timeline and Routing in its header. The routing uses GraphCanvas with an empty palette. A track linked nowhere shows "Goes nowhere". Delete takes links, never a track node. - Game playings route the same way, the output being the master of the playing. Decided without asking: a send ranges -60 to +12 dB like a track, default 0 dB Post. Mute closes the sends, the track's own level stays. Found on the way: the inspector built the Mode row with the send as it was when the rows were made. Setting Volume and then Mode wrote the old volume back. Both rows now read the current send when they change. Tests: - Unit song-routing (new): 13 green. Sound library: 4 new, 94 green. 11 counter-probes (loop on load, canConnect, solo, solo past the soloed track, mute, preFx latency, graph sync, delete guard, delays, taps, glide), each red. - Existing tests adjusted to the new bus names and send shape: song, bus-fx, song-play, graph registry, edge description. - e2e 65 on melektaus-atx: ALL PASSED, 43 checks (5 new). The first run caught the inspector bug. Counter-probe with the old closure: 2 FAILED. - Gate on melektaus-atx: typecheck, lint, format clean, 2 tests red (registry rule, edge shape), fixed and rerun locally: 56 green. - Not rerun after the per-send solo fix: e2e 65 and the gate.

Mix sounds through buses and a master (#325)
Until now every sound went straight to the speakers. There was no point where all of them came together, so nothing could turn the music down against the effects, and a compressor or a shared echo over everything had nowhere to sit. The bus technique of #346 was there already, only the end of the chain was missing. - Bus asset (Audio): Volume, Sound FX and Into. Into is empty for the master and never offers the bus itself nor a bus that already goes into it. The list is worked out when the menu opens, so a change made meanwhile counts. A loop that is in a project anyway sends the buses on it into the master. - The master is no asset. Its volume and sound FX are two new rows under Master in Project settings, one undo step each. A project written before has 1 and none, which is how it sounded. - Sound, instrument, pattern and song have a row Bus, empty for the master. Play sound, Play note, Play pattern and Play song have an input bus: From the asset, Master or a bus. Inside a song or a pattern only the bus of the song or pattern counts. - Set bus volume (bus, volume, time, easing) and Bus volume. An empty bus is the master. The volume set holds for the whole run, across scenes, over that of the asset. GameRun resets it at start and end. Set sound FX parameters without a voice now reaches the sound FX of the bus picked in its new bus input. - SoundLibrary: the master is the bus "mix", each bus "mix:<id>". Every bus, the playing masters of #346 included, ends there, and only the master is heard. setMix sets them up once a context exists, so an editor nobody listened to opens no audio device. The same mix again changes nothing, which lets the editor hand it over on every change of the project. - The tabs play as the game does: Sound, Sound FX, Instrument, Pattern and Song tab through the bus of their asset and the master. - Pause game does nothing to the buses (the user's answer 4b). A game that wants quiet in its pause menu sets a bus volume itself. - Streaming long music files is #349, split off as asked. Finding on the way: the Into menu first worked from a list made when the inspector row was built. After another bus was sent into the open one, e2e 34 saw it still offered. It is now asked on open. The SoundLibrary tests expected voices to end at the destination. They now end in the master, which adds its input, level and pan to every wiring and two gains to every list. Those expectations are updated, nothing else in them changed. Tests: - Unit buses (new): 15 green. Ten counter-checks, each red on its own: loop check, bus picked, reset at run start, bus of Set sound FX parameters, master volume in the settings, and in SoundLibrary default into the master, voices into the master, run volume over the mix, no context before a play, a playing on its bus. - Unit sound-library: 90 green (5 new). Node catalog: 416 green (9 new cases). - e2e 34 (melektaus-atx): ALL PASSED, 75 checks (3 new). The voice of the Sound tab was heard on mix:<bus>, that bus into the other, that one at 0.5 into the master. Master volume 0.6 via the dialog, undo back to 1. - Gate (melektaus-atx): CHECK EXIT 0, 262 files, 4072 tests. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> |

Keep the frame rate up while painting a big tilemap (#347)
Painting on the 60x60 map of a project with fifty objects dropped the editor to 20 to 39 fps. A profile of a brush stroke showed four causes, none of them the brush itself. - Each frame of a stroke previews the model. The asset and hierarchy panels then built every row anew, so every label became a new text and a new upload to the GPU. One run spent 46 % of the main thread in those uploads. ListView.setItems now keeps a row whose item draws the same (sameListItem) and builds only the rows that changed. - The brush drew the whole scene on every pointer event, on top of the preview. Now the preview draws what the stroke changed, once a frame. The rectangle tool asks for one drawing a frame for its box. - An animated tile made the view draw in the tick and the preview drew it again in the same frame. animate now asks just before the frame is drawn and stays out when the view was drawn since the tick began. - layoutSymbols ran on every drawing and costs up to the cube of the symbols. SymbolLayoutMemo keeps the spots while no anchor moves. - A painted cell made the map read every "x,y" key again, and once more for each of the eight neighbours of every cell. layerCells reads a layer once per content into an index by place. layerTiles and the blocking cells take their neighbours from there (neighboursIn). parseCellKey reads a key without split, with the same results. The test hook sceneRedraws counts how often the scene view was drawn. Not done: a painted cell still works out the tiles and blocking cells of the whole map again, so that part grows with the map. Tests: - Brush stroke on a copy of the project (stein2, Chrome): 20 to 39 fps before, 47.5 after, 55 to 57 without painting. Labels drawn again during the stroke 2012 before, none after. Scene drawings per frame 1.32 before, 1 after. - One painted cell, headless: 28 to 16 ms on 60x60, 109 to 49 ms on the same map doubled to 120x120. - frame-preview: 2 new, red with the old pointer redraw. - tilemap: 3 new (key reading, index, refresh), list-ping 1 new, symbol-layout 1 new. 5 single reversals turned each red. - e2e 39,40 (melektaus-atx): ALL PASSED, 107 checks (1 new, a fast stroke: 6 drawings in 6 frames, no label drawn again). With the row reuse and the pointer redraw reverted it fails: 24 drawings in 3 frames, and the panels draw their labels again. - Gate (melektaus-atx): CHECK EXIT 0, 260 files, 4038 tests.

Play a sound backwards with a Reverse switch on the asset (#321)
A sound asset can now play its stretch backwards. The switch sits on the asset, so every way the sound is heard plays it reversed: Play sound, a song item, an instrument's Sample and a Pitch in a sound FX. There is no Reverse node in the sound FX graph. The user dropped it, because playing backwards needs the whole sound in advance, which a bus or a Chip does not have. - The cut gets a `reverse` flag, stored as the asset property `reverse` (default off). The cut name ends in `~reverse` when it is on, so a reversed sound over the whole file is a cut of its own. - The handles keep marking the same part of the file. The reversed copy is made once, like any cut, and the fades follow what is heard: Fade in ramps at the end handle, Fade out at the start handle. - The Sound tab has a toggle with a left-pointing play triangle. Its playhead runs from right to left, and the wave draws the ramps at the edges they now belong to. The inspector has a Reverse row. - The icon is a tab header icon (`HEADER_ICON_SVG`, next to the snap magnet), not a top bar icon. The first gate run had it in the top bar set, and the test that fixes that set went red. - A song item draws the waveform of a reversed sound backwards. Lengths stay as they are. - The header label reads "Fade in" instead of "Fade in (ms)" and the fade fields are 8 px narrower. With the new button the readout was cut to "0.03 s of 0..." at 1280 px, now it shows in full. The inspector keeps the unit. Tests: - Unit sounds 22, sound-library 85 (1 new each). Counter-checks: without turning the samples round, without moving the fade in to the end, and without mirroring the peaks, all red. - e2e 34: ALL PASSED, 72 checks (2 new). The reversed stretch starts with the last samples of the forward one, and the playhead ran 0.75, 0.60, 0.45, 0.30, 0.15 over the whole file. - Gate: first run red, 1 of 4031 (the top bar icon list). After moving the icon, CHECK EXIT 0, 260 files, 4031 tests. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> |

Show what the song plays around a pattern as ghost notes (#339)
A bass line is written against the chords it goes with. Until now the piano roll showed only the pattern itself, so writing a part to fit the rest of a song meant switching between the Pattern and the Song tab. - A double-click on a pattern item remembers song, item and the round clicked into for that pattern. The place lives in the session, not in the project, and goes by the item's id, so moving the item moves the ghost notes along. - Opened from the Assets panel, the pattern shows the item of the last double-click. Without one, a pattern that lies in exactly one item of all the songs shows that item's first round. - Ghost notes are the pattern items of the other tracks all along the song, and on the own track the items before and after and the other rounds of the item. The round edited itself does not count. Sound items have no notes. - A ghost note sits on the row it sounds with: its own transpose, less the transpose of the item the pattern was opened from. - The roll draws them grey, without an edge, under the notes. Resting on one names its track and its pattern. - The header has a Ghosts switch, on by default, and names where they come from, e.g. "Tune · Bass · bar 5". - The time axis pans back to the start of the song, with bar and grid lines before the pattern. Fit still frames only the pattern. - A click or a paste outside the pattern no longer lands. Before, only the time left of bar 1 was closed, notes could still be drawn past the end, where they are kept but never played. - The rounds of a pattern item are now worked out in one place, itemNotes() in song.ts, which songSequence() and the ghost notes share. Tests: - Unit ghosts (new): 5 green. Counter-check with the round edited not left out and the own transpose not taken off: 2 red. - Unit piano-roll: 1 new (pan back to the song, lines before bar 1). Counter-check without the song's start: red. - e2e 65 (melektaus-atx): ALL PASSED - 38 checks (3 new). The first run was red on the tooltip check: the ghost note it rested on lay a fifth up, outside the rows Fit frames. The test now uses a tone. - e2e 64 (melektaus-atx): ALL PASSED - 30 checks. - Gate (melektaus-atx): CHECK EXIT 0, 260 files, 4027 tests. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> |

Send a track, a pattern item or a whole song through a sound FX (#346)
A sound FX could only be put on a single sound. Now a track, a pattern item, a Play pattern and a Play song send everything they play through one chain of it, as an insert in a DAW. A Play note gets one of its own. - Track: an FX box in the head next to M and S opens a menu of the project's sound FX, and the track's inspector has the row too. Order: items, track FX, volume, pan. - Pattern item: Sound FX in its inspector. Its notes play on a bus of their own into the track's bus. - Play pattern and Play song take fx and fx params. The chain sits on the master of the playing, after the tracks and before the level and the fades. Set sound FX parameters reaches it by the playback. - Play note takes fx and fx params next to the instrument's params. The FX parameters go by "fx:" so the two sets stay apart. Set sound FX parameters on a note changes a name both have in both. - A Pitch on a bus is a new PitchShifter: the phase vocoder of the PitchPlayer, fed while it plays. It cannot look ahead and is exactly one frame late at every pitch, 2048 samples. - That latency is made up. The other way of a Mix is held back by a delay of the same length. Every note and clip starts as much earlier as the buses it passes are late. The scheduler plans that much further ahead, and the first note waits that much after Play. - The Song tab waits for the chains before it plays and lets its buses go a moment after Stop. A playing in a game lets them go after its echoes and what the shifters still hold. - songBuses moved to its own file. Kept in song.ts it pulled the FX compiler into the node registry through an import cycle. Decisions of the user: one chain for the whole (1a), FX everywhere asked for (2a), Set sound FX parameters on playbacks (3a), and a pitch shifter of its own with exact latency compensation for a Pitch on a bus. Tests: - Unit pitch-shifter (new): 11 green. At 0 semitones the output is the input 2048 samples later, off by at most 1.2e-7. - Unit sound-library: 84 green, 8 new. Counter-checks (no early start, no Mix delay, chain made every time, tune misses the master) each turned their test red. - Unit bus-fx (new): 6 green, 4 counter-checks red. Scheduler ahead: 1 new, its counter-check red. - e2e 65 (melektaus-atx): ALL PASSED, 35 checks, 4 new, first run. Chrome at 44.1 kHz: the bus was 0.046440 s late, the note started exactly that much early. Offline the shifter moved 1 kHz to 2000 Hz and passed a click 2048 samples later. - Gate (melektaus-atx): CHECK EXIT 0, 259 files, 4021 tests.

Swirl and comb a sound with a Phaser and a Flanger node (#341)
sfxr's "phaser" is a comb filter, the sound plus a copy delayed by up to 2.9 ms. That is a flanger, not the phaser a guitarist knows. Both effects come in as nodes of their own, so each name fits its sound and sfxr is covered in full. Both run on the FX worklet like the Bitcrusher, because a feedback loop in Web Audio costs a render quantum per round. - Phaser: first-order allpasses (Stages 2, 4, 6, 8, 12) around Frequency, moved by a sine LFO Depth octaves wide at Rate Hz, with Feedback and Mix. An Envelope can move Frequency and Mix. - Flanger: a delay line of Offset ms. Sweep moves it on in ms/s from the start of the voice, an LFO adds up to Depth ms. As in sfxr the delay is mirrored at 0, and it never goes past 20 ms. Feedback comes back exactly one delay later. An Envelope can move Offset and Mix. - Mix 0 leaves the sound as it is, 1 is half sound and half copy. The notches are deepest there and the peaks stay at the sound's level. sfxr adds both at full, so its sound comes out 6 dB louder. - The Flanger's processor gets the start of its voice and begins the sweep on that sample. stageNodes takes it as a new argument `at`. - Explosion gets a Flanger in one draw out of two, with sfxr's offset and sweep and no LFO. Offset is offset^2 * 2.89 ms, Sweep is ramp^2 * 125 ms/s, signed so the direction holds. - Randomize draws a Flanger's offset and sweep like sfxr. Its LFO and feedback and all of a Phaser are drawn within bounds of their own. Mix and Stages stay, as a Bitcrusher's Mix does. Mutate moves them too, and a 0 stays 0. - New instrument preset Phased Pad: saw, Envelope, low-pass, Phaser of six stages. The other 14 are unchanged. - The Bitcrusher's worklet setup is now shared with both nodes (workletNodes), its behaviour is unchanged. Tests: - Unit phaser (new): 8 green. Counter-check with clamping at 0 instead of mirroring and a flipped allpass coefficient: 3 red. - Unit soundfx, sound-library, chip-presets: 45 / 76 / 14 green. Counter-checks: start time not passed on, phaser frequency eased linearly, sweep sign dropped, Phaser left out of Mutate, each red. - Unit core, viewport, graph: 179 files, 2979 tests green. - e2e 34 (melektaus-atx): ALL PASSED, 70 checks (1 new), first run. Chrome offline: 1 kHz notch RMS 0.0000 with two stages, 0.5657 with four. Flanger echo after 48 samples, swept echo at 533/534. About 47 Phasers (12 stages) or 63 Flangers fill the audio thread. - Gate (melektaus-atx): CHECK EXIT 0, 257 files, 3991 tests. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> |

Fade a sound's start and end apart, each along its own curve (#345)
A cut sound had one edge fade for both ends, always a straight ramp. Now its start and its end each have a fade of their own, and each fade has a curve of its own. - Fade in (ms) and Fade out (ms) replace Edge fade (ms), 5 ms each by default. Like before they apply only to an edge inside the file. - Fade in curve and Fade out curve each offer Linear (the default), Equal power, S-curve, Exponential and Logarithmic. A fade out runs its curve backwards. - The Sound tab's header has a field and a curve dropdown per edge. Each dropdown shows its curve as a small picture, rising or falling, and names it in its tooltip. With two named dropdowns the header was too wide at 1280 px and cut off the readout on the right. - The inspector shows the same four rows, the curves by name. - The wave draws each ramp in its curve rather than as a line. - A cut plays by <file>#<start>~<end>~<fadeIn>~<fadeOut>~<curveIn>~<curveOut>. - No migration, as asked in the issue: the old fade key is no longer read, so saved sounds start with 5 ms each and Linear on both. Tests: - Unit sounds, sound-library: 96 tests - Counter-check (fade out along the fade in's curve): 1 red - e2e 34 (melektaus-atx): ALL PASSED - 69 checks - Gate (melektaus-atx): CHECK EXIT 0, 256 files, 3978 tests Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> |

Give each account its own folder of uploaded files to delete (#344)
Uploaded images, fonts and sounds belonged to nobody. Every account saw every file in the pickers, and only an administrator could delete one, through the API alone. Now every account uploads into a folder of its own, sees its own files and nobody's, and can delete a file of its own that no project uses. - Files are stored as data/<kind>/<folder>/<sha256>.<ext>, and the folder is part of asset.file. A name without a folder belongs to nobody. - The folder is a random 12-character name kept in users.json and given with the first upload. Renaming an account moves no file, and a released game's URLs carry no account name. - The list shows the caller's own files and nobody's. An administrator sees all, each with owner and deletable. - DELETE takes the name with its folder. It answers 403 unless the file is the caller's or the caller is an administrator, and 409 while a project, snapshot or release of any account names it (FileUsage). The 409 names the caller's own projects only. - The pickers have a Delete button. The first press asks, the second deletes, and a refusal shows the server's reason. - A deleted account's folder stays and only administrators see it. - tools/migrate-file-owners.php moved every used file into the folder of the account using it (a copy each for two accounts) and rewrote projects, snapshots and releases. A project's revision goes up, so an open editor gets a conflict instead of saving old names back. - Font families are named after the hash alone, so a folder never ends up in a CSS family name. Run on stein2 on 2026-10-07, backup in /root/config-backup-20261007/data-before-344: 25 files used, 27 copies, 8 projects, 53 snapshots and 1 release rewritten, 30 unused files stay nobody's. Afterwards all 600 references resolve to a file in their owner's folder. Found while building: the Delete button cut its new label to "Del…" because a button does not measure itself again on a new text. The picker now lays its button row out again. Tests: - PHP files.test.php (new): 46 checks, counter-check 3 red - Unit core + editor: 220 files, 3403 tests - e2e 34 (melektaus-atx): ALL PASSED - 67 checks (2 new) - Gate (melektaus-atx): CHECK EXIT 0, 256 files, 3977 tests Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> |

Play tunes on 14 instrument presets next to the sfxr sounds (#329)
The Preset menu only had sfxr's effects: each a fixed pitch on every key that dies away by itself. Now its top half holds instruments to play melodies, basses and drums on. - Instruments: Square Lead, Pulse Lead, Echo Lead, Octave Arp, Synth Brass, Detuned Saws, String Pad, Organ, Flute, Bell, Pluck, Triangle Bass, Pluck Bass and Drum Kit. A line in the menu parts them from the seven effects below. - Their Chips follow the note, and all but Bell, Pluck and the drums hold it while the key is held. - They come out the same every time they are picked. Randomize and Mutate make a variant, as before. - They use what the graph already has: two Chips through a Mix for Detuned Saws, String Pad, Organ, Flute and Bell, an Envelope on a Filter's cutoff for Brass, Pluck and Pluck Bass, a Pitch for the detune and the octave, a Delay for Echo Lead and Bell. - Drum Kit uses single notes 36 to 46: kick, snare, closed and open hat on their General MIDI keys, each ending by itself. - A small Sketch helper lays the nodes on a grid. The sfxr presets use it too and come out as before. - Numbers keep to the steps of their rows. Pulse Lead's duty is 0.13, not 0.125, because the field rounds to 0.01. Tests: - Unit chip-presets: 12 green (5 new). Every instrument compiles without a problem, doubles its frequency an octave up, holds unless struck and is the same on every pick. The drum kit sounds on exactly 36, 38, 42 and 46. Countercheck with Follow note forced off: red. - e2e 34 (CI image on stein2, melektaus-atx was off): ALL PASSED, 65 checks (1 new). A first run had the scheduler's looped-bar check red by 10 ticks between two clock reads, which the presets do not touch; the second run was green. - Gate (stein2): CHECK EXIT 0, 256 files, 3974 tests.

Make an 8-bit sound with a Preset, Randomize or Mutate (#329)
A Chip could play a sound, but finding a good one meant typing a dozen numbers. sfxr's buttons do that in one click: a kind of sound drawn anew every time, a wild draw, or a small nudge. The Instrument tab now has the same, and plays the result at once. - Preset menu with Pickup, Laser, Explosion, Powerup, Hit, Jump and Blip. It puts a new graph in place of the instrument's, as one undo step: Notes for all 128 notes, Chip, Envelope, Filter, Bitcrusher, Output. The Chip keeps its own frequency with follow note off, so every key plays the same effect, and sustain 0 ends it by itself. - The presets are sfxr's generators, worked out into Hz, semitones and seconds with sfxr's own formulas, in chipPresets.ts. sfxr's envelope holds and falls in a line, ours falls quick at first. So the decay is three times sfxr's hold and fall. - Randomize draws every number of the Chips, Envelopes, Filters and Bitcrushers anew, as sfxr's randomizer does. Waves, filter types, the Bitcrusher's mix and an Envelope's from and to stay. - Mutate moves each of those numbers a little, one in two. A 0 stays 0, so nothing that was off comes on. - An input fed by an edge is left alone by both. Both are grey while the graph has none of those nodes. - Audition, off by default as in the Pattern tab, plays the note last played again 150 ms after a change to the graph rests. - Preset, Randomize and Mutate always play that note, for up to 2 s. - ReplaceGraphCommand swaps nodes and edges and keeps groups and notes. - The info on the right of the header kept 220 px and was cut off with the four new buttons. 140 px still fit "No sound picked". Not done: punch, filter sweeps and the phaser of sfxr (#341). Tests: - Unit chip-presets (new) 7. Counter-check: a wrong Hz formula and fed inputs not left alone turn 3 of them red. Unit tests of the instrument tab, graph commands and sound FX nodes: 49 files, 851 green. - e2e 34 (melektaus-atx): ALL PASSED, 64 checks (4 new): Preset, Randomize and Mutate, Audition, three undos back to the Sample. - Screenshot with a Laser preset: the header fits at 1280 px, the chain is fitted, the Chip is a saw with its duty grey. - Gate (melektaus-atx): CHECK EXIT 0, 256 files, 3969 tests.

Make 8-bit sounds without a file with a Chip node in instruments (#329)
An instrument could only play sound files so far. The Chip makes the sound of a note itself, the way old game consoles and sfxr did: a raw wave and what its frequency does over the note. A laser, a jump or a pickup is now an instrument and ends by itself. - Chip node with wave (square, triangle, saw, sine, noise and the periodic noise of the NES), follow note, frequency, duty, duty sweep, slide, delta slide, min frequency, vibrato, arpeggio and repeat. It counts in Hz, semitones and seconds, not sfxr's 0 to 1. - It runs as a third processor in the FX worklet. The math is a plain class, ChipPlayer, tested in Node. Every sample is worked out 8 times and averaged, as sfxr does. - Frequency and duty are AudioParams, so an Envelope can move them and a parameter can tune them while the note plays. A Pitch behind a Chip moves its frequency directly, without the phase vocoder. - Below its min frequency a Chip ends and tells the page. Without the worklet it is silent and its note ends at once. - An Envelope with sustain 0 now ends its note once the decay is over, for every source under it, Samples too. Before, a note with duration 0 ran on silently until a Stop sound. - A note made of Chips alone needs no file. playNote and the wait for the bytes no longer drop it for having none. - Inputs that do nothing as things stand are grey in the inspector. idleParams is told which inputs are connected, so a connected one always counts. The credit names sfxr (Tomas Pettersson, MIT) and jsfxr, which turned out to be public domain, not MIT as the plan in #329 said. Tests: - Unit chip (new) 12, sound-library +4. All of tests/core, tests/viewport, tests/editor/graph and tests/editor/inspector: 178 files, 2953 green. - Counter-checks: semitones read as /24 turn 4 chip tests red. Without the sustain rule and the file check 4 library tests fail. - e2e 34 (melektaus-atx): ALL PASSED, 60 checks (2 new). Offline in Chrome a square at 220 Hz plus 12 semitones and duty 0.25 gave 329 periods in 0.75 s, up 0.249. 64 noise voices for 2 s rendered in 2.0 s, about 63 at once. Live a 0.2 s note with sustain 0 was gone after 0.26 s. - Gate (melektaus-atx): CHECK EXIT 0, 255 files, 3962 tests. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> |

Crush a sound to fewer bits and a lower rate with a Bitcrusher (#322)
A new effect for sound FX and instruments makes a sound rough like an
old console. It rounds the sound to fewer steps and holds it at a lower
sample rate, and all three of its numbers move while the sound plays.
- Bitcrusher node with bits (1 to 16, not only whole), rate (100 Hz to
48 kHz, sample-and-hold) and mix. A mix typed in at 0 leaves it out.
- It runs on the audio thread as a second processor next to the pitch
player. The module is now fxWorklet.ts and the test hook is called
fxWorkletUrl.
- A play that needs the worklet waits for it, for a Pitch or a
Bitcrusher alike. Without the worklet the sound goes through as is.
- Bits and mix move in what they hold, the rate in octaves. An
Envelope can move all three in an instrument.
- A stage that runs on the worklet is stopped with its voice, like the
drivers of an Envelope or a Mix.
- The math is a plain class, Crusher, so it is tested in Node.

Cut a sound to a stretch of its file in its own Sound tab (#343)
A sound asset now opens in a tab that shows its file as a waveform. Two handles set where the sound starts and ends in the file, and that stretch is the sample: Play sound, a song item and an instrument's Sample all play it and nothing else. The file itself is never changed. - The asset has three new rows: Start (s), End (s) and Edge fade (ms). End 0 is the end of the file, the fade is 10 ms by default. Older assets have no values and play the whole file as before. - Every way of playing asks playedSoundOf() for a name instead of the file: the file, or <file>#<start>~<end>~<fade> for a cut. - SoundLibrary makes the cut from the decoded file the first time that name plays and ramps each edge inside the file over the fade. Length and peaks of a cut are read from the file without a copy. - Cut buffers can be made again at any time, so the library lets the oldest go past 64 Mi samples. A voice holds its buffers itself. - The tab draws min/max per pixel from 256-sample block peaks, and the samples as a line when zoomed in far. Wheel zooms, the middle button pans, as in the music tabs. Wave, cut and ruler sit under a mask, so a handle panned out of view does not draw over the panels beside. - Dragging a handle moves that edge, dragging elsewhere spans a new stretch. One drag is one undo step for both edges. Whole file puts the handles back, Play or Space plays the stretch with a playhead. - The inspector preview and the Sound FX preview play the cut too, and the song lanes draw and repeat it. Tests: - Unit: sounds 20, wave-view 8 (new), sound-library 68, plus 258 in the touched areas (instrument, song, pattern, inspector, tabs) - e2e 34 on melektaus-atx: ALL PASSED, 57 checks (7 new) - Gate on melektaus-atx: CHECK EXIT 0, 253 files, 3936 tests Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> |

Record a take from the microphone in the Song tab (#342)
A song could only be filled with sounds that were made somewhere else. Record plays the song from the cursor and takes the input meanwhile, so a part played along lands on the bar it was played to. - An audio worklet takes the input's samples on the clock the song plays on. Each run carries the frame it was taken at, so the take is cut where the song was heard to start. The output's and the input's latency are taken off, as far as the browser reports them. - The take goes up as mono 16-bit WAV. Sound, a new track "Recording" under the track clicked last and the item at the cursor are one undo step. The sound is named "Song – Take 1", 2, 3 and so on. - While recording the take grows red with its waveform on its track, and a meter beside the input dropdown shows the level. The lanes take no edits then, only a middle-drag pans. - The loop is not used while recording. The song plays once through and on past its end until Stop, Play or Space keep the take. Esc throws it away and nothing goes up. - Echo cancelling, noise suppression and auto gain are off, nothing is played back. The input picked is kept in localStorage. - A take stops by itself at the size a sound may have. A failed upload offers Retry, Download WAV and Discard. - The API takes sounds up to 256 MB and bodies of the same size. nginx and PHP were raised to match outside the repo (body 256m, upload and post 256M, memory_limit 512M). - The pure rules (cut, cap, WAV header, name, track) live in core/music/take.ts. The scheduler tells where it started on the audio clock. - The e2e browser gets chromium's fake microphone and skips the permission prompt. Each run leaves its take in the sound store. Found on the way: - The header was too full with the new widgets and cut the track and item count on the right. Input dropdown and meter are narrower now. Tests: - Unit take.test.ts: 7 new, svg-icons adjusted to 8 toolbar icons - e2e 65 (melektaus-atx): ALL PASSED – 31 checks (+4) - Gate (melektaus-atx): CHECK EXIT 0, 252 files, 3923 tests - Probe on stein2: a 3 s take of the test tone, peak 32767, 285100 bytes, waveform seen in the screenshot Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> |

Size notes by either end and pan before bar one in music tabs
A round of small fixes to the Pattern and Song tabs: what the ruler and a pan do in both, and a few things the tabs carried that were in the way. - A middle-drag can take bar 1 up to half the grid or lanes in. The time before it is drawn dark on the ruler, the grid and the lanes. Nothing lands there: a click draws no note, a drop shows no frame. - A press or drag on the ruler puts the start on the nearest grid line, no longer on the one before the pointer. - A new song has one track instead of four. The "+ Track" row under the heads is gone, a head's menu adds tracks above or below. A song still keeps at least one, so that menu is always there. - A note can be sized by its left end too: the start goes to the nearest grid line and the end stays put, never before tick 0. - An end of a note under the pointer lights up and shows a resize cursor, as on an item of the Song tab. Tests: - Unit: piano-roll, song-edit, song, song-play 52 tests. Two new cases for the left end and the pan, the song fixtures add their tracks themselves now. - e2e 64+65 on melektaus-atx: ALL PASSED - 50 checks (+2). e2e 65 adds its tracks through the head's menu and clicks the ruler three quarters into a bar, which only the nearest line passes. - Gate on melektaus-atx: 251 files, 3909 tests, CHECK EXIT 0. - A probe shot of the piano roll panned in: the time before bar 1 dark, the left end of a note lit.

Zoom with the wheel and set the loop on its own strip in music tabs
The ruler of the Pattern and Song tabs did two things with one drag,
and the wheel did three things with Alt and Shift. Both now do one
thing each, and the Song tab gets a few edits it was missing.
- The ruler has a loop strip along its top. A drag there sets the
loop, a press or drag below it moves only where playing starts.
- The wheel only zooms: the time over the grid, lanes and ruler, the
rows over the keys, the tracks over their heads. Alt and Shift no
longer change it. A middle-drag still pans.
- Tracks can be zoomed from 28 to 160 px. Below 46 px a head shows
only its name, M and S. An old saved view gets the old height.
- A click on nothing in the lanes picks the song itself.
- A right-click on an item opens a menu with Delete instead of
deleting it. The inspector has no delete buttons any more.
- A sound item goes up to +12 dB, a track up to +12 dB. A pattern
item stays at 0 dB, since a note is held to unity.
- An end of an item under the pointer lights up and shows a resize
cursor. A long item marks every point where it starts over.
- The Pattern tab has an Audition switch in its header, off at first.
Only with it on does a note sound when drawn, grabbed or moved.
The keys down the left sound either way.
- A looped sound item draws every round alike. Each round is drawn
from its own start, and each column shows the loudest part of the
sound it covers instead of one sampled bucket.
- A song is at least one bar long instead of four. An empty song
fits that bar across, and Play song ends after the last item.
- The ghost notes held back in #334 got their own issue, #339.

Play and stop a song from a behavior in the game #336
A song could only be heard in its tab. Now a game plays it through Play song and ends it through Stop song, with its tracks as they are set. A playing pattern or song also no longer undoes the pause of the toolbar. - Play song plays from the start of the song and then round the loop of its ruler, so an intro is heard once. Without loop it plays once to its end. Inputs are song, volume, fade in, loop (on by default) and detached (off by default). It gives out playback. - Stop song stops one song, every song for none, or one playback by its number, over its fade out. Stop sound with no sound named stops songs too. Stop pattern with no pattern named stops only patterns. - Songs play side by side, as patterns do. They are owned like a sound, so leaving the scene ends one unless it is detached. Pause game and the time scale leave the music alone. - Each playing is heard through a master of its own, silent until its first note. The fades move it, and a song's tracks sit inside it on buses of their own. They go once the playing and its voices have. - Notes and clips are struck the same way in the editor and the game (strikeNote, playClip). What a sequence needs comes from one place (core/music/needs). Findings: - Reading the audio clock resumed a suspended context. A playing pattern read it every 25 ms and so undid the toolbar's pause. The library now leaves a context alone while the toolbar holds it. - A pattern played once to its end asked the list of playings about its voices, and that list asked the pattern again. Once its last voice was gone this ran until the stack overflowed. The scheduler of a playing now asks only after voices. - e2e 64 reads the playings through __gm.sound.playbacks() now. Tests: - song-play.test.ts (new): 8 tests, node catalog +8 cases - sound-library.test.ts: 66 tests, 4 new - e2e 64 (melektaus-atx): 23 of 23 checks passed - e2e 65 (melektaus-atx): ALL PASSED, 22 checks (+4) - Gate (melektaus-atx): CHECK EXIT 0, 251 files, 3903 tests - Counter-checks: the old way of asking after voices, a clock read that wakes a held context, and a start after a fade out began each fail 1 test Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> |

Lay patterns and sounds out on tracks and play them as a song #334
Patterns could only be heard one at a time, in their own tab or from a behavior. A song lays patterns and sounds out on tracks along one time axis and plays them through the scheduler of #332, the third piece of the music tools of #330. - New asset type song under the heading Songs, with four empty tracks, 120 BPM in 4/4 and a grid of a bar. Tempo, meter and grid are rows in the inspector. Tracks, items and the loop are the asset's data, held to their rules on load and in every command. - A track has a name, volume, pan, mute and solo. Each is heard on a bus of its own, so a change reaches what is sounding at once. - A pattern item repeats its pattern for as long as it is, with a transpose and another instrument if wanted. A sound item plays its sound as a clip at its own speed, round and round, through a sound FX if wanted. Both have a volume on top of their track's. - Cut back at the left end or split, an item starts as far into what it plays as the cut is: ticks into a pattern, seconds into a sound. - The tab shows the heads with M, S, volume and pan, the ruler of the Pattern tab and the items, a pattern with its notes, a sound with its waveform, a missing asset red. Patterns and sounds are dragged in from the Assets panel. Body, right and left end move, lengthen and cut back, Alt leaves the grid. Ctrl+C/V/D/A, Ctrl+E splits where playing starts, Delete, arrows. A double-click opens a pattern item in its tab. - What is picked is a new selection of its own, so the inspector shows the item or the track, with a button to delete it. - The scheduler plans clips beside notes. Where the playhead starts or jumps back inside a clip, it is taken up that far into its sound. A clip fades out at the end of its item or of the loop. - The editor plays one piece at a time: a pattern started stops the song and the other way round. - The rules are pure functions in core/music/song, editor/song/ songView and songEdit. Findings: - The suites of |

Play and stop a pattern from a behavior in the game #336
A pattern could only be heard in its tab. Songs come with #334, and only then can #336 play them in a game. Until then a game plays a single pattern, looped or once, through two new nodes. - Play pattern plays the whole pattern through its instrument at its own tempo. The loop on the ruler is only for editing. Inputs are pattern, volume, loop (on by default) and detached. It gives out playback, 0 where there is no instrument or no note. - Stop pattern stops one pattern, every pattern for none, or one playback by its number. Let ring lets notes with an Envelope fall away in their release. - A playing is numbered and owned like a voice. Destroying the object, Stop sound with nothing named and the end of the run stop it. Stop sound with a voice takes a playback too. - Each playing runs on a scheduler of its own (core/music/playbacks). It waits for its files first, and a stop that came earlier wins. - The scheduler has an end for a sequence that does not loop. It stops waking there and is done once its last notes are. - The worker clock moved to viewport/wake.ts, so SoundLibrary can use it without importing music.ts. Tests: - pattern-play.test.ts (new): 8 tests, node catalog +7 cases - e2e 64 (melektaus-atx): ALL PASSED, 23 checks (+3) - Gate (melektaus-atx): CHECK EXIT 0, 248 files, 3854 tests - Counter-checks: no end in the scheduler, and no owner for the playing, each fail 1 test Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> |
