About Epicycle: MIDI Sequencer

Epicycle is a MIDI sequencer for iPhone and iPad. Every rhythm is a Euclidean ring, and each track's parameters generate its pattern.

MIDI OUT, CLOCK AND EXPORT A one-time lifetime unlock adds live MIDI out, MIDI clock in and out, and .mid export, so you can drive and sync external…
