Generative Sequence & Logic

Yeast

MIDI pattern utility for generating motion, variation, and new musical ideas. A professional playground for generative logic.

Tab 01 / Play

Interactive Arpeggiation

Lock sequences to grid divisions and explore global arpeggiation patterns.

Latch mode and intuitive performance controls make it easy to find new rhythmic ideas. Fine-tune your gate times and velocity patterns for expressive MIDI generation.
