This paper discusses the Jam-O-Drum multi-player musical controller and its adaptation into a gaming controller interface known as the Jam-O-Whirl. The Jam-O-World project positioned these two controller devices in a dedicated projection environment that enabled novice players to participate in immersive musical gaming experiences. Players' actions, detected via embedded sensors in an integrated tabletop surface, control game play, real-time computer graphics and musical interaction. Jam-O-World requires physical and social interaction as well as collaboration among players.

In this paper we describe the digital emulation of a optical photosonic instrument. First we briefly describe the optical instrument which is the basis of this emulation. Then we give a musical description of the instrument implementation and its musical use and we conclude with the "duo" possibility of such an emulation.
