Screen: hold a key to grow a note (longer hold = bigger, longer-lived; higher on the key = louder), drag across keys to strum, drag the shape to spin it, tap it to play up the scale. Keys A–K and Q–I play too.

Headset: poke the floating keys (faster poke = louder); pinch the shape to pick it up and move it, let go mid-twist to spin it; quick-pinch inside it for a note; pinch a note to pluck it out and throw it; fingertips knock notes around. Pinch the bar under the keyboard to move it. Controllers: point + trigger, grip to grab.

MIDI CC in: 0 shape · 1 spin · 7 volume · 12 reverb · 64 hold · 69 spin lock.
