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. TWO FINGERS, TWO JOBS Raise two fingers and your hand switches to a second sound, or turns into a controller for an effect: sweep a Wah, stretch an Echo, speed up a Vibrato. Six effects to play with: Reverb, Pulse, Echo, Wah, Vibrato and Crunch. SAVE YOUR SETUP Presets keep every sound and effect on both hands. Start from one of six, from Classic to Conductor, where one hand plays and the other shapes the sound. MORE TO PLAY WITH • Note Guides show where every note sits on the screen • Volume and octave for each hand • Make a fist to mute without hiding your hand • Portrait or landscape, iPhone and iPad • Works with VoiceOver, Voice Control and Larger Text PRIVATE BY DESIGN Hand tracking happens entirely on your device.
