Apparatus audio-visually modelling a musical instrument

摘要

In a music and graphic apparatus, a performance input device provides performance information effective to control generation of a music sound. A timbre input device provides timbre information effective to specify a timbre of the music sound. A sound source is operative based on the timbre information to simulate an acoustic instrument capable of creating the specified timbre. The sound source is responsive to the performance information to generate the music sound as if voiced by the acoustic instrument with the specified timbre. A model image generator generates a model image 50,54 graphically representing at least a part of the acoustic instrument. A dynamic image generator is operative according to the performance information for generating a dynamic image graphically representing an operation (51,52,53,54) of the acoustic instrument. A graphic synthesizer composes the model image and the dynamic image with each other so as to dynamically model the operation of the acoustic instrument in synchronization to the generation of the music sound.
