Trigger and transpose your patterns in real time.

Matrix Polynator is a polyphonic step sequencer VST3/AU plugin for Mac and Windows, inspired by the legendary Matrix Sequencer from Propellerhead (Reason). Matrix Polynator turns any MIDI keyboard into a live performance instrument — draw your pattern once, then play it in any key, any time.

Record melodies and chords, one step at the time.

Every step can hold a full chord. Draw notes with your mouse or record from your midi keyboard one step at a time, no BPM stress. Each note or chord you play becomes the next step. Simple as that.

Few controls. Endless results.

8 patterns across 4 banks (32 in total). Switch mid-performance — your pattern waits for the next step, beat, or bar before switching. Copy it to a new slot, hit Random for subtle variations, combine with live transposition and every pattern becomes something new every time.

Automate Gate, Rate and Shuffle

Every parameter you need, fully automatable from your DAW. Shape your pattern over time — tighten the gate, shift the groove, push the shuffle. Set it and let it evolve.
