Wave your hand in front of the camera to play. Hand position
sets pitch (left ↔ right) and volume (up ↔ down).
How to play
Touch mode — drag on the pad: X
sets pitch (left = low, right = high), Y sets
volume (bottom = silent, top = loud). A
second finger adds vibrato (X = rate, Y = depth).
Air mode — wave your hand in front of the front
camera. Hand X = pitch, hand Y = volume. With two hands visible:
your right hand sets pitch (closer-to-camera = louder
like a real theremin antenna), your left hand adds
vibrato.
Pick a scale to snap pitches to a key — set it to
Continuous for true theremin glide.
Glide smooths big pitch jumps; turn it down for
snappy attacks, up for liquid swoops.
