A generator that writes like a drummer. Then a pro sequencer to shape it.
You already own a drum library. What you don’t have is a drummer who writes a solid first take in any of 31 genres, and an editor deep enough to make it yours.

Built for people who edit.
Every part of the groove is yours to change, down to a single hit.
A new take every press
Generate rewrites every lane in the style. Undo brings the last take back, and the dice on a lane rewrites just that part.
Per-step everything
Velocity, offset, ratchets, probability and conditions per step, plus pitch, level and pan.
Groove templates
Straight, triplet, shuffle, two-step / UK garage, dotted, laid back and pushed.
Keep your drum plugin
MIDI-only mode with MIDI out per lane: let Drummer-1 write and Battery, XO, Groove Agent or your sampler play.
1 to 12 lanes
Size the kit to the track. Each lane has its own drive, punch, EQ, filter and ducking, and the Finish stage makes the kit sound mixed and mastered.
Straight into the session
Drag into your DAW or export WAV, MIDI, per-lane stems and loop-ready audio. Locks to your DAW’s playhead, and everything saves with your session.
