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

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 23922ee was red on the memory check of the stream:
the tab's renderer grew by 94 MB with nothing decoded. Play mode
made garbage of its own and was read before a collection. Both
readings in play now come after one, and the check compares the
growth streamed with the growth decoded (3.7 MB against 59.8 MB).
- The ratio handle sat on the right edge of the picture, where a
widget's hit area ends. The curve is inset by the grab radius.
Tests:
- Gate (melektaus-atx): 282 files, 4338 tests (17 new)
- e2e 34 (melektaus-atx): ALL PASSED, 116 checks (6 new)
- Counter-checks: an inverted ratio search, stop() letting go of
every node and a drag without its least step each fail exactly
their test.
- Looked at the tab in a screenshot: a blip at -4.4 dB came out at
-16.7 dB, the gap tinted, the threshold line at -24.
