From the project's README ("Features"):
- Thirteen engines (below), each with its own factory presets; every factory sound has a category (BASS, LEAD, PAD, PLUCK, KEYS, DRUM, FX, OTHER) to browse by
- Four tracks, one synth part each with its own engine and sound (drums are the DRUM engine); 8 voices shared between them. ALGORITHM selects the track on every page
- Sequencer: 64 steps per track with chords, ties, accent, slide, per-step chance, velocity and ratchets (a step played 2, 3 or 4 times in its length); a piano roll of the steps, where KNOB 3 sets a note's length; a drum grid (white keys = steps, black keys = lanes); SEQ > DETAIL: the cursor step's chance, ratchet, nudge and velocity on the four knobs, drawn as lanes over the steps; automation: recording of knob moves per step (an automation icon marks the cards it drives); live loop recording with overdub; step recording at the cursor (REC on SEQ > STEP while stopped), one chord at a time or note by note (MENU > CHORD ENTRY ADD); divisions listed by length, 4 bars to 1/32; loading a sound never touches your patterns
- Timing: live recording keeps when you played each note, as a per-step NUDGE (1/16 of a step, half a step early to 7/16 late); the track's QUANTIZE decides what plays: ON (the default) every step on the grid, as always, OFF your own timing. Nudges can also be set by hand
- Parameter locks and the AUTOMATION list: hold a step on SEQ > STEP (or the drum grid) and turn a knob to set …
