Show a Delay node as a device with its echoes over time (#393)
After the Chip, the Envelope, the Reverb and the one-knob devices, the Delay is drawn as a device of its own size too. Its screen shows what time, feedback, damping, wet and ping-pong make of a sound, and a light runs over the echoes at the beat they come at. - DelayPanel: a 680x280 plate in the Compressor's brushed aluminium, now exported as ALUMINIUM. A screen, levers for Sync and Ping-pong, knobs for Time, Feedback, Damping and Wet, and an Echo lamp. - The screen draws the sound as a white bar and each echo as a bar one step later. A bar is as tall as the echo is loud, evenly in dB to -60. It turns from warm white to rust as the damping takes the highs. With ping-pong the bars alternate above and below, the first left. - At most 24 bars are drawn, and the screen says how many more are heard. Under it stand the step and the end of the tail, above it where the highs of the first echo end. - The running light: DelayFace.tick returns true while the node is in the picture, so the editor keeps drawing, as for the Particles tab. The light goes round the span in real time, a bar glows as it is passed, and the lamp blinks with every echo but not with the sound. - On beats the screen counts at 120 BPM, as the tempo of the voice is not known in the graph. The time knob then names the note, dotted and triplet ones included. In seconds, 2 s and up reads "2 s max". - delayView holds the rules apart from the drawing: layout, tapers, echoTrain, echoCutoff for k rounds of the Butterworth low-pass, sweepAt and the texts. At wet 0 the rest is drawn faint. - delayEchoes in the core counts the echoes heard. The tail of a voice and the screen use it both. DELAY_ROWS, DELAY_SYNC and PING_PONG are exported. - Knob.reformat writes the number anew when its format changes, here when Sync switches between seconds and beats. - The test hook __gm.delay.panel returns knobs, levers, idle settings, the echoes drawn, the texts and where the light is. - Instrument presets give the Delay 4 columns. Echo Lead and Bell use one. In the picture of Echo Lead nothing overlaps. Found on the way: a node with a face draws no setting rows. The e2e check of a bypassed Delay (#354) read "Bypass: true" from them. It now checks the faded node and the stages heard, as before. Tests: - Unit delay-view: 17 tests, new. Counter-check: the first ping-pong echo on the right turns the side test red. - e2e 34 (melektaus-atx): 136 checks, 1 new. - Gate (melektaus-atx): 288 files, 4416 tests. - Pictures looked at: default, ping-pong, beats with damping, 83 echoes at 50 ms, wet 0, and the preset Echo Lead.

Show Pitch and Mix nodes as one-knob devices in green and blue (#390)
The Gain has been a small device with one big knob since #384. The Pitch and the Mix are just as much a single number, so they now look and work the same way. The Mix also gets a lever for its curve, which until now was only a row in the inspector. - GainPanel and GainFace become KnobPanel and KnobFace. Each node is described by a KnobDevice: its plate, its row, how the knob turns, and an optional lever. The Gain looks as before. - Pitch: a green 160x160 plate with a bipolar knob for Semitones. 0 stands straight up and taper 2 puts an octave at 43 % of each half, so small steps near 0 are easy and the full +-64 is still there. - Mix: a blue 180x200 plate, the lever on top and the knob below. The knob has A and B engraved at the ends of its turn. The lever reads "crossfade" down and "both at center" up with its lamp lit. A flip is one undo step. - A wired Semitones or Mix greys the knob, as for the Gain. - The instrument presets give Pitch and Mix two columns. In the graph they are 281 and 261 units wide, more than one column of 240. - The test hooks __gm.pitch.panel and __gm.mix.panel return the same shape as __gm.gain.panel, plus the lever. Tests: - Unit hardware-view: 15 tests, 3 new (Pitch turn, lever above the knob and ends on the Mix plate). Counter-check: taper 1 turns the Pitch test red. - e2e 34 (melektaus-atx): 134 checks, 1 new. - Gate (melektaus-atx, together with #391): 287 files, 4397 tests. - Pictures looked at: Gain, Pitch and Mix in a row, Pitch at -24.5, Mix with both curves, the Bell preset without overlaps.

Show an Envelope node as a device with its ADSR curve (#388)
The Compressor, the Gain and the Chip are devices in the graph. The Envelope was still a list of rows, and its shape was left to the imagination of whoever read the numbers. - The node is a plate of 520x280 in pale sea green. Its inputs are on the left, out and value on the right. - A dark screen draws the curve over a note in amber. A letter sits above each stage, its time below it, and the sustain in percent above its line. - The time on the screen is squeezed. Each stage is as wide as the root of its seconds, at least 3 %, and the hold has a fixed fifth. So 5 ms of attack still shows beside a release of 3 s. - The falls use SETTLE, as the player does. With sustain 0 there is no hold and no release, and the screen says NOTE ENDS. - Attack, Decay, Sustain and Release are chrome knobs. The times use taper 4, so 5 ms sits an eighth of the way and 1 s not quite half. - From and To have no range a knob could turn through. They are NumberFields on the plate, typed in or scrubbed. - The decay at sustain 1 and From/To while nothing takes value are faded. While a link takes value, the bezel says what it moves between, as VALUE 400 TO 3500. The UI font has no arrow. - Instrument presets give an Envelope 3 columns of 240. - Test hook __gm.envelope.panel(nodeId). Tests: - Unit envelope-view: 6 new tests for the plate, the knob turn, the idle settings and the curve. A linear decay turns two of them red. - e2e 34 (atx): 1 new check on the Laser preset (device between its ports, curve ends with the decay, decay knob and scrubbed To field each one undo step). - Probe pictures on stein2: Synth Brass preset, pad, pluck, organ and an Envelope whose value moves a Chip. - Gate (atx): CHECK EXIT 0, 286 files, 4383 tests. The first run was red on the font test (#214) for an arrow in the bezel text. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> |

Show a Chip node as a device with its wave and its pitch (#386)
The Chip had eleven numbers in rows and nothing that showed what they do to a note. Its node is now a device of one size like the Compressor's, and two screens draw the wave and the pitch from the settings, worked right in the instrument graph. - ChipPanel is 840x280 in the warm grey of a handheld console. A button per wave, the "follow note" lever and a chrome knob per number, grouped Oscillator, Slide, Vibrato, Arpeggio and Repeat. - The wave screen draws two periods as loud as the Chip plays them, a square at its duty. toneValue and periodicSteps come out of chip.ts, so the screen and the worklet share one formula. - The pitch screen draws what slide, delta slide, vibrato, arpeggio and repeat make of the pitch over a note. It ends where the note falls below "min frequency" and starts from A4 while the Chip follows the note. - Idle settings are faded, wired ones greyed and locked, as the rows were. Every change is one undo step. - Knobs take a bipolar range: 0 straight up, the taper bends each half. Slide, delta slide, duty sweep and arpeggio use it. - The Compressor's auto-gain lever is now a Lever with a name of its own, which the Chip uses for "follow note". - Presets give a Chip five columns, as a Filter has four since #385. Found on the way: - With the Chip this wide the Laser preset is about 3060 units. In a 1280 px window Fit stops at the least zoom of 0.25 and cuts the Notes node off. The zoom limit is left as it is. Tests: - Unit: chip-view (9 new), knob (1 new), chip, chip-presets and hardware-view, 53 green - e2e 34 on melektaus-atx: ALL PASSED, 131 checks (1 new). The first run was red on the check itself: a Laser's "min frequency" can lie above A4, and the screen then rightly says the note ends at once. - Gate on melektaus-atx: CHECK EXIT 0, 285 files, 4377 tests - Counter-check: a square drawn with its duty mirrored turns the wave test red Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> |

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> |

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).

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> |

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> |

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.
