Live performance
Live stage
Play with your hands, not a timeline.
Start audio and camera, then use a single hand to perform. The built-in synth plays in-browser, and an external MIDI output can receive note and control data too.

No gesture
Waiting to start.
Gesture map
Five moves, one instrument.
The page reads broad hand poses instead of tiny finger choreography, so it stays readable in a normal webcam setup.
Fist
Stops notes, freezes playback, and sends all notes off to MIDI.
Point
Maps left-to-right position to notes in the current scale.
Pinch
Changes filter brightness, output energy, and MIDI control messages.
Peace sign
Cycles through scales so you can shift mood mid-performance.
