AirPiano - The AirPiano is a musical device that is played by moving your hands above it in the air. The AirPiano is a virtual matrix of keys and faders, each assigned with MIDI messages and ready to be triggered. The length of a triggered note is equivalent to the time a hand is placed on the corresponding virtual key. This is also confirmed by LED feedback.
At the moment the AirPiano is only a prototype, so there is no word on when it will go into production and how much it will cost.
