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.
