Kit
Every track runs a different pattern algorithm. Turn the knobs and the rhythm reshapes itself — you steer patterns rather than draw them.

Chaos injects random flips across all tracks without changing the underlying pattern, so pull it back and the rhythm returns. Mutate makes a permanent small change. Set different lengths for polymetric drift.

Built-in synth for previewing without hardware, alongside MIDI out. Kit in the transport bar sets every track's voice at once; each track can then be changed on its own. Pitched voices play the track's note.

Quadrivium

Six algorithmic rhythm generators driving hardware over Web MIDI, with a circular polyrhythm display.
MIDI out needs Web MIDI over HTTPS or localhost. The built-in preview synth works anywhere.
