We describe a unique MIDI-based spatial sound system featuring a network-driven bank of four RSS-10s (Roland Sound Space Processors) driving an eight-transducer circumferential speaker array in a" 3D Theater", enabling a three-dimensional dynamic musical space. Sound sources can be choreographed by adding dynamic positional gestures to standard MIDI files. Our sequencing system interprets such files, partitioning their data into two streams: one for MIDI tonal events, sent to synthesizers, and the other for positional data, sent simultaneously to sound spatializers, clients in a multimodal musical control of sound spatialization, synchronizable with stereographic 3D contents, for spatializing music to give real presence to an audience.
