How it works.

Picks the note in the scheme.

Top is high, bottom is low. Spans the octaves.

Velocity. Pale speaks softly.

Opens the lowpass. Vivid rings brighter.

Noise percussion. B&W images map by brightness instead.

Seven diatonic colours. C D E F G A B. Folk, bright, plain.

Twelve chromatic colours by circle of fifths. Richer, stranger.

Painting sounds the note as you touch the canvas. Clicking a palette swatch sounds it too. The mapping teaches itself.

Play / stop.

Undo. Add Shift to redo.

Eyedropper. Picks the colour at the cursor from the painting.

Click any number in the control bar (bpm, brush, trans, loops) and type directly. Arrow keys nudge by step.
