I love strange applications like this one!
Compass Synthe is a cutting-edge musical instrument using sensors of iPhone. Sounds are allocated to 360 degrees.
Let’s perform Compass Synthe by swinging your iPhone vertically and horizontally. You may need some exercises to perform Compass Synthe perfectly.
However, there is no doubt that you can have fun with this new age musical instrument. Also, marvellous sounds may be created when few people perform this app together.
The app is free.
