Compass Theremin

The Compass Theremin is a sensor-based music instrument which uses readings from your phone's gyroscope (compass sensor), to control the pitch of a synth oscillator.

Simply put - to play this instrument you hold your phone and turn it around in different directions, or alternatively hold it in one direction and turn around yourself.
It's as fun as it sounds and you'll get the hang of it very quickly.

You can choose between different scales, attack / release times, wave forms, and vibrato amounts.
