Index Theremin

Theremin is a tiny instrument you play with thin air. Hold up one finger in front of your phone: raise it for higher notes, move it sideways to play louder. That's it, you're playing. Make a fist to stop. A SOUND FOR EVERY MOOD • Theremin: the classic eerie wail • Dusk: a dark, slow, melancholic synth • Aura: an airy, voice-like pad • Glass: a soft, bell-like shimmer • 8-Bit: a video-game square wave ALWAYS IN TUNE Auto-Tune snaps you to a scale (major, minor, pentatonic or every note) in any key. Hard for the robot effect, Smooth for a gentle glide. PLAY A DUET Turn on Duet Mode and each hand becomes its own instrument, with its own sound and settings. MORE TO PLAY WITH • Reverb and Pulse effects • Volume and octave for each hand • Make a fist to mute without hiding your hand • Portrait or landscape, iPhone and iPad PRIVATE BY DESIGN Hand tracking happens entirely on your device. Nothing is recorded, uploaded or collected.
