ABSTRACT:
A music processing system that processes music events includes a performance supervisor and a graph object. The graph object defines an ordered graph of music event processors, through which music events are routed. The graph object has a graph interface with methods allowing an application to insert and remove event processors in the graph. In addition, the graph interface has a method that can be called to update a music event data structure that represents the music event. This updating consists up supplying an identification of a music event processor that is next to receive the music event. Each event processor has a processor interface, which includes an initialization method and a process event method for performing the actual processing of a music event. Each processor supports one of a plurality of delivery timing modes, and also supports a subset of available event types. When inserting a music event processor in a graph, an application program can specify which instrument channel the event processor is to act upon.
