- We present the prototype of a hybrid instrument, which uses two contact microphones to sonify the gestures of a player on a generic surface, while a gesture localization algorithm controls the pitch of the sonified output depending on the position of the gestures. To achieve the gesture localization we use a novel approach combining attack parametrization and template matching across the two microphone channels. With this method we can correctly localize 80 $\pm$ 9 % of the percussive gestures. The user can assign determined pitches to specific positions and change the pitch palette in real time. The tactile feedback characteristic of every surface opens a set of new playing strategies and possibilities specific to any chosen object. The advantages of such a system are the affordable production, flexibility of concert location, object-specific musical instruments, portability, and easy setup.
