The Resource-Instance Model of Music Representation

Traditional software synthesis systems, such as Music V, utilize an instance model of computation in which each note instantiates a new copy of an instrument. An alternative is the resource model, exemplified by MIDI "mono mode", in which multiple updates can modify a sound continuously, and where multiple notes share a single instrument. We have developed a unified, general model for describing combinations of instances and resources. Our model is a hierarchy in which resource-instances at one level generate output which is combined to form updates to the next level. The model can express complex system configurations in a natural way.
