What n001se does
- Four FM drum tracks play kick, snare, hat, perc, click or metal sounds, and a fifth track runs a 303-style acid line.
- Patterns are rolled at random within limits you set, with drums one to eight bars and acid one to four.
- Evolve keeps moving steps as the loops go round, and Deviance makes every hit sound slightly different.
- Black keys mute tracks, step through bars, roll a new pattern or sound, and undo up to twelve moves.
- Each track has reverb and delay sends, a moving filter and drive, while Chaos brings beat repeat and reverse.
