DrumSequencer (VST3/AU)

Demo version here: DrumSequencer Demo

DrumSequencer is a stochastic MIDI drum sequencer that generates evolving rhythmic patterns through probability, euclidean distribution, and controlled randomness. It runs as a VST3 plugin on Windows and macOS. DrumSequencer outputs MIDI only. You need a drum instrument (sampler, drum machine plugin) on a separate track to hear sound.

Ten independent drum tracks, each with its own density, timing, direction, and expression controls. Instead of programming every hit by hand, you define rhythmic rules - then let the sequencer surprise you.

Every parameter is automatable and responds in real time - tweak density, shift, fill, or swing while the pattern plays and hear it change instantly.

Mutate lets the pattern evolve on its own: notes drift to new positions cycle after cycle while the overall density stays locked. The result is a rhythm that breathes without losing its shape.

Save your patterns as presets, export and import full banks, and preview any track's sound with a single click.

Enjoy making music!
