Pinchi is the result of a research experiment that looks into to possible connections between gesture control and sound modulation. It is probably best described as a digital granular theremin. It utilizes the pinch gesture and enables the user to hold and sculpt sound in mid-air, which provides unusual sound design capabilities.

The sound recording is activated by placing both palms above the Leap Motion. This enables three seconds of recording. The recorded sound can be sweeped through by moving the hand horizontally. The distance between the thumb and the pointing finger determines the grain size. The pitch can be changed by moving the hand up and down, while depth controls the low-pass filter.

The software is written entirely with MAX/Msp and Jitter. ManosOsc is used for OSC communication.
