This paper will describe the design and implementation of PadMaster a real-time improvisation environment running under the NextStep operating system. The system currently uses the Mathews/Boie Radio Drum as a three dimensional controller for interaction with the performer. Pad- Master splits the surface of the drum into virtual programmable pads which can be grouped into scenes so that the behavior of the surface can be subtly or drastically altered during the performance.
