The classic orchestra has a diminishing role in society, while hard-disc recorded music plays a predominant role today. A simple to use pointer interface in 2D for producing music is presented as a means for playing in a social situation. The sounds of the music are produced by a low-level synthesizer, and the music is produced by simple gestures that are repeated easily. The gestures include left-to-right and right-to-left motion shapes for spectral envelope and temporal envelope of the sounds, with optional backwards motion for the addition of noise; downward motion for note onset and several other manipulation gestures. The initial position controls which parameter is being affected, the notes intensity is controlled by the downward gesture speed, and a sequence is finalized instantly with one upward gesture. The synthesis employs a novel interface structure, the multiple musical gesture interface. The actual control mechanism is a color sensitive camera that by filtering out certain colors can identify the movements of a laser pointer. The gestures of the pointer control either sound, note or timbre parameters depending on the angle of incidence of the light. Several synthesis methods are presented and the control mechanisms are integrated into the multiple musical gesture interface. This enables a number of performers to interact on the same interface, either by each playing the same musical instruments simultaneously, or by performing a number of potentially different instruments on the same interface.
