Designer Omer Yosha has come up with a prototype for a high tech piano that makes the player seem more like a conductor than a mere pianist, commanding sound with the skilled positioning of the hands.
Unlike the imaginary Air Guitar, the AirPiano is a tangible, sophisticated piece of technology as you can see in the video below.
The instrument is elegantly designed and features a virtual matrix of faders and keys that correlate with MIDI instructions. These instructions are fed to and interpreted by software including the high-end Ableton LIVE.
The prototype consists of up to 24 keys / 8 faders and transfers data via USB. There is no sustain pedal as this too can be controlled with the hands simply by holding your position over the surface.
