PURPOSE:To obtain musical tone data according to a performing method and to facilitate the proper use of the musical tone by adding wave form data which are reset or not reset according to the performing method to driving wave form data. CONSTITUTION:A musical tone synthesizer is composed by adding an adding means 201 consisting of an adder to add driving wave form data issued from a memory 21 to wave form data, and a reset means 202 consisting of an one- shot circuit 13 to send out value 1 for time corresponding to the word length M of a shift register 24 when sound starting information Kon becomes the value 1, an AND gate 14 to input the output signal and reset flag of the circuit 13 and to send out the reset flag when the information Kon is the value 1, and an AND gate 12 reset the data sent out from an adder 28 when the output signal of the gate 14 is zero in value. Thus desired musical tone data can be obtained. |
