Abstract

We describe the design, implementation, and evaluation with musical applications of force sensitive multi-touch arrays 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. We have developed two pad systems, one with 24 pads and a second with 2 arrays of 16 pads each. 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. Our experiments with the pad arrays demonstrate that we can efficiently deal with large numbers of audio encoded gesture channels - 72 for the 24 pad array and 96 for the two 16 pad arrays.
