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>
