PURPOSE:To make it possible to synthesize also a musical instrument sound of a holding system such as a violin in a musical tone synthesizer capable of approximating the physical structure of an acoustic instrument by an electronic circuit. CONSTITUTION:An input data generation part 110 inputs input data corresponding to a bow speed or the like obtained at the time of bowing a string to the 1st filter part 120, respective delay equipments 142, 152 in delay parts 140, 150 corresponding to respective strings feed back and input feedback data corresponding to the oscillation of respective strings to the 1st filter part 120 and the filter part 120 calculates the 1st driving data based upon the input data, the feedback data and a parameter generated from the 1st parameter generation part 130. A residual data adding part 190 adds the 1st driving data to previously stored residual data and inputs the added result to the delay part 140 corresponding to the string as the 2nd driving data. Repeat of the operation makes it possible to attain interference operation of the bow and the strings and synthesize violin sounds. |
