PROBLEM TO BE SOLVED: To perform the processing not making a reproducing musical sound signal unnatural and to perform the time base companding processing without delaying the sound generation start timing by providing a waveform forming means and a control means controlling so as to start the waveform formation by the waveform forming means from a waveform on a position of corresponding mark information. SOLUTION: A CPU 1 performs the whole control of a device such as the control of a digital signal processor(DSP) 8, the state detection processing of an operation piece group 6 and a keyboard 4. Then, when an operator inputs reproducing speed information showing a reproducing speed of the waveform data by a speed information input means, the time information showing the position of a waveform on the time base is generated by a time information generation means. When the time information arrives at the position of the mark information showing the position on the time base in the waveform data, the CPU 1 controls so as to start the waveform formation in a formant system by the waveform forming means from the waveform on the position of the answering mark information. |
