Sound 8 app for iPhone and iPad

Sound 8 is an eight track sound looper controlled via touch and accelerometer.
Circles, which represent tracks, can bounce off the screen edges and float in ”zero-gravity”.
Positions (x = volume, y = pitch) are controlled via touch and the accelerometer, or can be assigned randomly. Furthermore, each tracks Pan can be adjusted individually.

Sound 8 comes with eight included sounds and allows for importing sound files directly on the device via a download link or from a Mac or PC using iTunes File sharing.
