IPC: G10H1/24
Filed: 1995-05-31
Abstract: PURPOSE: To prevent the occurrence of a noise in an output signal when a signal processing parameter and a signal processing program are revised by adding an envelope signal generation means generating an envelope signal changing facing to 0 or 1. CONSTITUTION: Respective parameter values are not inputted directly to multipliers 52, 54, but are connected through envelope generators 70, 71. Then, the envelope signal changing facing to 0 or 1 is generated according to a set envelope parameter, and by multiplying an output signal of a signal processing means by the generated envelope signal, an output signal level is controlled. Thus, for instance, when a signal processing parameter is revised, first of all, the envelope parameter is revised, and the output level of the signal processing means is made zero while spending a prescribed time so as to cause no noise. Then, the signal processing parameter is revised, and thereafter, the envelope parameter is revised, and the output level is returned to an original level while spending the time.
