Gestures: Doodles to Music

The first sequencer in the Sequins suite. Draw shapes to generate evolving polyrhythmic MIDI patterns using prime number phasing. Transform visual gestures into complex musical textures with simple drawings.

More innovative sequencers coming soon...

Prime Number Phasing

Each shape loops at prime lengths (3, 5, 7, 11) creating evolving polyrhythmic patterns that never quite repeat.

No downloads, no installations. Connect directly to your DAW via Web MIDI API from any modern browser.

16 MIDI Channels

Layer up to 16 independent channels, each with unique patterns and instrument assignments.

60+ World Scales

Quantize to scales from around the world. From major pentatonic to Hungarian minor, find your sound.

Intuitive Gesture Mapping

Draw to create. Shape complexity becomes rhythm, position becomes pitch, drawing speed becomes velocity.
