Getting started

From the project's README ("Playing it"):

Every page has the same layout: a header (page, track, pattern, tempo, play/stop), the body, and the knob bar. The knob bar shows what KNOB1–4 do on the current page, always in the same four colors. It starts on SCOPE (the HOME page), where the keys play the selected track.

Control What it does
SELECT Choose the track (1–9).
PRESETS Choose the pattern (1–40). While playing, the one you stop on plays when the current one ends.
ALGORITHM Set the tempo.
PLAY Start or stop.
REC Record what you play into the pattern.
SAVE Save the song. If it's playing, it saves when you stop (saving pauses the sound).
SEL Show the next page of knobs. On PATTERN with a synth track: toggle slide on a step.
ARP On PATTERN: set the ratchet of the step under the cursor.
ENV Clear the pattern. It asks first: OCT+ clears, OCT- cancels.
…
