Version 2.0 for iOS
You use the built-in motion sensor by rotating or accelerating your device. The default configuration applies these manipulations to specific musical elements as shown below:
- A rotation around the X-axis controls the tempo
- A rotation around the Y-axis is applied to the velocity
- A general acceleration affects the articulation
See the figure below to learn more about the coordinate system of the iPad.

The built-in controller can be turned on or off. If you are a left-hander you might want to reverse the rotation around the Y-axis by touching the hand symbol.
Consider using a gamepad if you are looking for an improved control of your musical performance.
