## Ther Description
Ther-i-phone allows you to play your device like a musical instrument. Touch the screen and drag to play, and move - rotate, turn, spin or accelerate - your device to change the sound in real-time!

Your device's sensors, and the position on the screen where your finger is, can be used to control different aspects of the sound - you can set up what controls what.  Want vibrato only if you're facing north?  You can do that.

It has two oscillators, whose pitch, waveform, vibrato, volume, and whether it uses a chromatic scale or continuous pitch, can be mapped to any sensor Ther-i-phone supports, including pitch, yaw, roll, heading, device acceleration, as well as left-to-right and up-and-down finger position.

It includes several built-in preset configurations, and has the ability to save your own presets.

Use it to make music, for weird sound effects, or as a stealthy way to produce odd sounds at unexpected times, at the touch of a finger!
