Air Accordion
This is an experiment inspired by the chromatic button accordion's compact keyboard layout and the Leap Motion Controller.
The chromatic button layout works surprisingly well on the computer keyboard, and gives the keyboardist a far greater range than standard mappings imitating piano keyboards.
The Leap Motion Controller allows music to be played through hand motion, allowing accurate volume control calculated for every virtual reed. There are five reed banks designed to give an authentic tremolo and harmonics.
Made originally by @benzguo. Leap-Enabled by @ehrlicp and @binxed.
