Tilt Theremin is a musical app for the Android platform. Using different sensors, it lets you play melodies in the air, like the original Theremin.
This new version introduces 4 new effects: Echo, Phaser, Chorus and Reverb. Proper support for the gyroscope sensor is also in place, making it possible to use two axis instead of just one. The gyroscope sensor is supported on most devices running Android 2.3+.
The full version ($1.49) has 6 different sounds, 7 octaves and adjustable settings for all effects. (Google Play | SlideME)
The free Demo version has only 2 sounds and 2 octaves and can not adjust settings of effects. (Google Play | SlideME)
