Clockworks vs Epicycle

Clockworks turns rhythm into geometry. Build polyrhythms by layering rotating shapes on a clockface — each shape's sides become evenly-spaced beats, so a triangle and a pentagon played together weave intricate cross-rhythms with zero math. • Layer multiple shapes, each its own voice • 10 instruments — sampled piano, e-piano, guitars, plus synth keys, organ, marimba, vibes and more • Built-in drum kits with a step sequencer • Dozens of scales across many categories for instant melodic results • Scene-based arrangement to evolve your loop over time • Pro FX: 3-band EQ and BPM-synced echo • Export to MIDI, audio (WAV), or sheet music PDF No theory required — just add shapes and listen.

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.
