Performance

The followind table shows some tests. Frames per second (fps) refers to frames captured and processed in a second.

Hardware	Overclock	Speed
Raspberry Pi 2 B	no overclock	14 fps
Raspberry Pi B	no overclock	1.8 fps
Raspberry Pi B	overclock set to High	2.2 fps

Clearly, Raspberry Pi 2 is recommended for this application, since 2 fps makes Air Piano hardly usable in a music playout.
