Grainulator
Grainulator turns any audio into a playable instrument. Granular synthesis breaks sound into tiny grains that can be stretched, scattered, pitched, and layered in real time. Touch the grain cloud to shape your sound — every parameter is designed to be performed, not configured.
Core Systems
Grain Cloud Engine
128 simultaneous grains per voice, 8 voices. Up to 1,024 grains in real time with independent pitch, position, density, and spread control.
Multi-Touch Control Surface
Touch the grain cloud directly. Drag to scrub position, pinch to control density, two-finger rotate for spread. Every gesture maps to sound.
Kinetic Parameters
Momentum, spring-loaded returns, and gravity zones. Parameters don't just move — they respond with physics that make digital controls feel analog.
Modulation Matrix
Route any source to any destination. LFOs, envelopes, velocity, aftertouch, and external MIDI all available as modulation sources.
Built-in Effects
Reverb, delay, filter, and saturation — tuned for granular textures. Each effect designed to complement the grain engine.
Visual Feedback
See every grain. The visualization isn't decoration — it's a control surface. Understand your sound structure at a glance.
Three Layers
From first touch to full control.
Play
Load and perform
Load any audio file and start sculpting immediately. The main controls — position, grain size, pitch, density — are front and center. Touch the cloud, hear the result. No manual required.
Shape
Modulate and refine
Expanded parameters, modulation routing, and built-in effects. Assign LFOs, draw envelopes, route velocity to grain density. For when you know what you want and need precise control.
