Abstract

PURPOSE: To reduce attenuation processing time by determining an attenuation rate subsequently on the basis of a detection by means of an attenuation rate detecting means and thereby carrying out a rapid attenuation process. CONSTITUTION: An arithmetic and control means 6A controls an arithmetic processing means 6B and a rapid attenuation processing means 6C based on musical sound information, key pressing/releasing information, and rapid attenuation demanding information, as well as on an envelope waveform signal and a target value arrival signal from the arithmetic processing means 6B, and rapid attenuation control information (target value, rate, etc., in a rapid attenuation) from the rapid attenuation processing means 6C; also, the control means 6A forms an envelope completion signal imparting to a musical sound producing and allocating device 3. In other words, on the basis of the attenuation rate at the point of time in starting a rapid attenuation process, a subsequent attenuation rate is determined. As a result, with a click sound increased or avoided, a sharp attenuation rate is set from the point of time in continuously processing rapid attenuation.
