Musical instrument pioneer Roger Linn (Linn Drum, Akai MPC) demonstrates his latest creation, the touch-pad based Linnstrument.



The prototype consists of a multi-touch, pressure-sensitive, high-resolution USB touch surface. 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. It is able to sense independent and simultaneous x (pitch), y (timbre) and z/pressure (expression) data from each finger within each 3/4″ square cell of the note grid. This permits independent control of the pitch/timbre/expression envelopes of each note in real time as you play, and a very high degree of solo expression without sacrificing polyphony and therefore the ability to produce both chords and highly expressive solos at the same time.
