Grain Engine
A real grain scheduler, not a delay in disguise.
- Up to 16 grains per voice, with size, density and window shape
- Spread for position and pan, separate pitch jitter
- Freeze and reverse playback
- In tune at any sample rate
Grain Sources
Ready-to-play material, built in.
- 13 sources: sine pad, vocal, saw stack, glass, bell, plucked string, wood, FM sweep, noise and more
- Sine Pad, Vocal AEIOU, Saw Stack and Glass evolve along the buffer: Position changes the sound
- All tonal sources tuned to the same note
Playable Clouds
Granular that behaves like an instrument.
- 8-voice polyphony with filter, two LFOs and a mod matrix
- Poly, mono and legato modes with pitch bend
- LFOs, chorus, delay and pump sync to tempo
Step Sequencer
Write lines on a piano roll, not with sliders.
- Piano-roll grid from C2 to C5: tap to place notes, drag to draw
- Per-step gate, slide, accent, probability and ratchet
- Swing and four play directions
- 40 ready-made sequences, plus your own
Arpeggiator & XY Pad
Built to be played, not just programmed.
- Arpeggiator with 11 patterns, 16-step rhythm mask, swing and velocity modes
- XY pad drives any two parameters — grain position included — with bypass
- Master clock: host-locked in your DAW, tap tempo standalone
FX Rack
Seven effects on board.

A sound library that grows with you.
