Euclid Fill
Euclidean trig fill: pattern length, pulses, and rotation.
A Euclidean fill for sample trigs. Hold a TRACK key and press PAGE, and a window opens (title and target tracks, STEPS, PULSE, ROT, and a live pattern bar). YES writes the rhythm onto the held tracks' sample-trig mask.
This edits sequencer trigs; it is not the DSP EUCLID effect, which modulates filter or amplitude. It leaves PROJECT > CONTROL > SEQUENCER alone, so it coexists with SCALE QUANTIZER.
Access
Hold a TRACK key and press PAGE. Targets are the track keys held when the
window opened; with none held, the current audio track. TRACK + PAGE again
closes it, as does NO. FUNC + PAGE (SCALE SETUP) and PAGE alone stay stock.
Not in an official remix; build the test remix euclid-fill.
Hardware: cursory testing on Sam's MKII (owner report, 16 Oct 2026).
Operation
- STEPS is the pattern length (with PER TRACK, the first target track's length). It is shown, not edited.
- PULSE defaults to 5 and ROT to 0; they are not saved.
- YES writes the Euclidean trigs on the targets, NO closes.
Controls
| Control | Does |
|---|---|
| TRACK + PAGE | open / close |
| UP / DOWN | move the cursor between PULSE and ROT |
| LEFT / RIGHT | step the focused value by 1 |
| A | PULSE |
| B | ROT |
| LEVEL | turn the focused value |
| YES | write the trigs on the targets |
| NO | close |
Status: on hardware: cursory testing on Sam's MKII (owner report, 16 Oct 2026); builds and boots under the port; fill math gated in verify_euclid_fill.
Module facts (developers)
TRACK + PAGE: Euclidean sample-trig fill (STEPS=pattern len / PULSE / ROT; A/B knobs).
