Deep Control.
Endless Textures.

Multiple Playheads

Create multiple independent granular playheads, each with its own set of parameters and modulatable filter.

Modulation Matrix

Virtually every parameter can be modulated—including LFOs modulating other LFOs for complex, evolving motion.

Multi-Touch Performance

Use the 3-finger 2D touch pad to control up to 6 assignable parameters simultaneously for expressive real-time manipulation.

Per-Head Filters

Each playhead has its own modulatable filter, giving you granular control over the tonal character of every grain stream.

Re-routable Effects

A flexible effects section with re-routable signal flow lets you sculpt your sound and create evolving granular landscapes.

Scale Support

Built-in scale support keeps your granular explorations musically coherent and playable.
