Sequence (2013)

Sequence is the first euclidean sequencer for iOS/iPhone. The circular patterns are visualized in a unique geometric form, extending into sound as layered rhythms. Sequence lets players mix up to 8 of these patterns, creating intense polyrhythmic tracks perfect for electronic or experimental music. The app comes complete with 30 classic gamelan and drum samples and supports virtual MIDI for increased control. Attributed mostly to free giveaways, the app has attracted ~15,000 downloads and sees ~2,000 weekly sessions.

Sequence was originally conceived as as a piece for The Machine Orchestra. In this form, Sequence was a structured improv for six human performers and 48 musical actuators. The 2011 premiere was performed by me, Perry R. Cook, Jim Murphy, Mo Zareei, Colin Honigman, and Owen Vallis.
