ABSTRACT: In this paper, we present the sound synthesis machine. The machine is a pa signed specifically for the task of generating mu the physical behavior of musical instruments. and easily scalable, offering much higher perfor would be possible using commercially available machines demonstrate that single chip system mance to simulate ensembles of instruments. system includes a special purpose communical chip unit.
