Sequence is a euclidean pattern generator with sample playback and MIDI.
The circular patterns of notes in Sequence are generated by an algorithm created by Eric Bjorklund. Originally developed for timing sequences on spallation neutron source accelerators, the musical potential of the algorithm was first recognized by Godfried Toussaint, a researcher interested in musical geometry at McGill University.
The algorithm finds the most ideal temporal distribution of pulses given a number of steps, giving a recognizable performance of western and African rhythms when input with odd and even pulses and steps. In summary, it makes great polyrhythmic techno.
Sequence 1.0 features a collection of about 30 samples for your techno pleasure. The app also sports MIDI output to pipe to your favorite iOS sampler, DAW, or hardware device.
On the roadmap for version 2.0, we'd like to introduce Audiobus support, functions for recording sessions, and the ability to import your own samples. We'll also probably add OSC and support the iPhone 5 screen.
