Monoleap

Monoleap is a new musical instrument for the iPAD, capable of playing monophonic sounds with rich expression, without having to look at the screen.
Monoleap lets you play anywhere on the screen using custom fingering patterns, while controlling the instrument expression using vertical and horizontal hand movements. It comes with a built in sound, but is designed to be used as a MIDI controller for playing your favorite software or hardware instruments.
