We describe the design, implementation, and evaluation with real musical use of a force sensitive multi-touch array of touchpads. 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.
