ElectroKraft has introduced the Sonar*Axe, an “experimental sci-fi MIDI controller using a sonar sensor to detect hand position (generating notes), and a photocell to generate changes in note octave.”

The Sonar*Axe can be used to control any MIDI-compatible device.

ElectroKraft specializes in machines “designed to alter, change and morph the standard canned sounds of any midi drum machine, synth or keyboard. They are alternative midi controllers, using things like photocells and sonar sensors instead of keys or buttons, giving them a very Theremin-like functionality.”
