PURPOSE:To synthesize a musical sound while reproducing the feature of a musical sound generation source by resetting the delay in a filter for reflected wave arithmetic when a musical sound which is different from the sound source for a last musical sound is outputted and not resetting the delay when the same musical sound is outputted. CONSTITUTION:A reflection coefficient supply part 200 resets unit delay devices 161 - 163 to zero when an input reset mode signal (e) is ON (High). When the input reset mode signal (e) is OFF (Low), on the other hand, the unit delay devices 161 - 163 keep on holding their values. A driving part 120, a conversion part 121, a key-ON processing part 123, and unit delay devices 161 - 163 and multipliers 171 - 174 of a delay part 220 synthesize a musical sound corresponding to a reference clock, so progressive wave pressure qo is outputted from a terminal 190 as the musical sound which is affected by a reflected wave differing with a pitch. Further, reflected wave pressure qi which is outputted from a terminal 191 is inputted to the conversion part 121. |
