This BA Thesis project describes the development of an improvisation system and user interface to electronically augment the jazz piano performance through the use of a motion capture device, the Myo armband. This device sends via bluetooth its inertial data along with detected poses of the hand. The improvisation system consists in a series of gestures mapped to sonic events and efects, recalled by the performer with the only use of his hand’s movements.

Some of the software devices built for this system were clip and loop players, samplers, parameter controllers, Theremin-like synths and freeze devices. The whole work was programmed by the author in Max/MSP environment and Ableton Live.
