PROBLEM TO BE SOLVED: To make it possible to execute sound recording waveform processing and reproducing waveform processing without complexing device constitution so much by loading a first or second prescribed program on a signal processing circuit (DSP) and parallel performing both of the sound recording waveform processing and the reproducing waveform processing. SOLUTION: The signal processing circuit 205 performs individually signal processing for the musical sound waveform data from a mixer 204 at every channel to return again the processed result to the mixer 204. At this time, the circuit 205 obtains the delayed data by using a delay memory 111 at need. The function of the signal processing circuit 205 is controlled by a loaded microprogram, and performs the signal processing such as waveform processing or effect giving, etc., at the time of sampling and resampling. Then, the signal processing circuit 205 performs the signal processing for the musical sound waveform supplied from a waveform memory 109 to sound record the result, and supplies an output performed with the signal processing of the musical waveform supplied from the waveform memory 109 to an external sound system. |
