"The prototype consists of a multi-touch, pressure-sensitive, high-resolution USB touch surface from a company called TouchCo (details below).
A printed transparency containing the note names is attached to the top, and another clear sheet with each square cut out is attached above it in order to provide tactile feedback of the borders between notes.
An program written by a friend and fellow music/art/technology enthusiast named Tim Thompson translates the TouchCo's proprietary USB messages into TUIO messages sent over OSC.
A Max/MSP patch written by me and my wife Ingrid receives the TUIO/OSC messages, converts the x/y/z data into note locations, pitch, timbre and pressure data and synthesizes the sounds."
