4Pockets Audio shared this sneak preview of Euclidean Sequencer For iOS, described as an alternative incarnation of the classic step sequencer.
It is based on Euclidean rhythms, developed by computer scientist Godfried Toussaint in 2004. Euclidean rhythms have their roots in Greek mathematician Euclid’s algorithm, which involves using the greatest common divisor of two numbers to place hits in a sequence as evenly as possible across a set timing divisions.
You don’t have to worry about the math – you can just use Euclidean Sequencer to generate complex musical sequences.
You can define up to 4 Euclidean rhythm parts, each part is referred to as a band. The bands are labelled A-D and colour coded RED, ORANGE, GREEN and CYAN. Together these 4 bands create a pattern, and you can create up to 16 seperate patterns per song patch.
Since each band can specify its own note sequence and output MIDI channel, you can create some quite sophisticated rythms patterns, driving 4 seperate instruments at once. Even better you can seamlessly switch patterns to create even longer evolving sequences. Patterns follow a specified key, scale, or defined chord.
You can also use MIDI input to automatically make note sequences conform to the currently playing chords, remotely enable bands and seamlessly switch patterns.
Details 0n pricing and availability are still to be announced.
