Each of the touchpads supports a three dimensional representation of musical material: two spatial dimensions plus a force measurement we typically use to control dynamics. Our system uses 24 pads laid out in a ?brick wall? style array that fits nicely under the two hands. We emphasize the treatment of gestures as sub-sampled audio signals. This tight coupling of gesture with audio provides for a high degree of control intimacy. %8 07/06/2007
