PURPOSE:To obtain a natural musical tone and eliminate a sound break by processing and outputting an input acoustic signal and an acoustic signal read out of a storage means according to stored algorithm. CONSTITUTION:A sound source 5 reads data on a waveform and an envelope out of a memory 6 for a sound source according to music information inputted from a CPU 2 and processes the data, and a digital musical tone signal is outputted from a SEND terminal to a DSP 7. Then the DSP 7 performs an effect process for the digital musical tone signal from the sound source 5 by a delay memory 8 by using a coefficient transferred from the CPU 2 and outputs a final output musical signal to a mixer 9 through an output I/F. The digital output musical tone signal from the mixer 9 is converted by a D/A converter 10 into an analog signal and a stereophonic output is obtained from left and right speakers 13L and 13R. Thus, a total effect process is performed in a sampling time to eliminate a break of the output sound, thereby obtaining the natural musical tone. |
