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. Layer rings of different lengths for polymeter, and hear them on the built-in sound engine with no external gear. EUCLIDEAN RINGS Each track is a ring, and you can run up to eight at once. A track's pattern follows from its parameters, so you see the rhythm as a shape. POLYMETER Give tracks different lengths and they play together. Loop-lock protects one track's pattern while you change the others. SCENES Save pattern states as scenes and launch them with quantize. FREE TO PLAY Epicycle is free to download. The full sound engine and every creative feature are free, up to eight tracks, with no time limit. 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 hardware and apps. Requires iOS 18 or later. VoiceOver is supported.
