PROBLEM TO BE SOLVED: To suppress the generation of a noise by eliminating a variation in the sound volume of a musical sound emitted in a mixed manner as for a musical sound generation technology for simulating a sounding mechanism of an electrical organ of a drawbar system.SOLUTION: Waveform data by sine wave synthesis are copied to generate copy waveform data 305 of #0 to #78 for each of a plurality of pitches. Each OSC 401 of #0 to #78 repeats an operation to generate pitch waveform data by reading waveform sample data in each waveform data of #0 to #78 in parallel by aligning phases among a plurality of pitches at a reading speed corresponding to each pitch regardless of the presence/absence of an instruction of performance. Each EG 402 of #0 to #78 applies strength change characteristics to each pitch waveform data generated by each OSC 401 of #0 to #78, and sounds out the pitch waveform data when a performance instruction to designate each pitch is generated. An MIXER 403 mixes each pitch waveform data sounded out by each EG 402, and outputs the pitch waveform data as musical sound waveform data 404.SELECTED DRAWING: Figure 4 |
