1. A system for providing visual music (VM) synthesis, the system comprising: a VM synthesizer having a controllable VM instrument construct comprising: a plurality of synthesizer control inputs coupled with control module outputs of a plurality of parameter control modules comprising a set of emitter parameter controls and a set of particle parameter controls; and a plurality of parameter stack outputs synthesized as a function of the synthesizer control inputs, each parameter stack output defining a particle system having a respective particle emitter that is defined according to the emitter parameter controls and emits a respective plurality of particles defined according to the particle parameter controls; a particle system processor comprising: a plurality of parallel particle engines, each coupled with at least one of the parameter stack outputs, and having a particle supersystem output that characterizes the parameter stack outputs as a particle definition; and a memory manager coupled with the plurality of parallel particle engines and having a memory layout output indicating assignments of respective portions of the particle definition to memory blocks of a graphics processor.
