OPEN ARCHITECTURE MUSIC SYNTHESIZER WITH DYNAMIC VOICE ALLOCATION

An architecture for a synthesizer of music or other sounds which comprises an input device which supplies real time input signals indicating selected voices, a voice program memory which stores voice programs for respective voices, and a sound processing module including an array of digital signal processors, which is coupled to the input device and the voice program memory, and responsive to real time input signals to execute a group of voice programs in the voice program memory to generate selective voices in real time. Resources coupled to the input device and the voice program memory dynamically assign voice programs for selected voices to the group of voice programs in response to the real time input signals. Further, resources are available for replacing a particular voice program in the group with a voice program for a selected voice in response to the real time input signals. The voice program memory includes a first memory which stores a plurality of voice programs, and a second memory which is coupled to the sound processing module and the first memory, which stores the group of voice programs for execution by the sound processing module. The resources for dynamically assigning a voice program to the group includes a system for transferring a selected voice program from the first memory to the second memory in real time. An audio output device, including a speaker, is coupled to the digital signal processor for producing sound in response to the sound data.
