DIVA - Sound generation

Rather than using conventional sound synthesis methods the physical modeling techniques of musical instruments (model-based sound synthesis) are used in DIVA system. The basic idea in physical modeling is to imitate the sound production mechanism of an acoustic musical instrument. This approach produces automatically sound that resembles that of the real instruments. The DIVA sound synthesis module consists of several physical instrument models that are controlled with standard MIDI interface. Currently implemented instruments are guitar, bass and flute which are synthesized in a single workstation in real time. Remaining instruments needed, in particular percussion sounds are generated with standard MIDI-compatible synthesizers that is connected in to the same workstation. The synthesised sound is delivered to the auralization module through an optical ADAT interface.
