Abstract
Frequency information is stored in a tone coefficient memory and accumulated to obtain address information for reading out a musical sound from a musical waveshape memory by a musical sound generating circuit. Envelope information is stored in an envelope coefficient memory and accumulated to obtain address information for reading out an envelope waveshape from an envelope memory by an envelope generating circuit. An address counter performs address assignment for operating the musical sound generating circuit and the envelope generating circuit on a time-divided basis. The frequency information and the envelope information are respectively accumulated by a common accumulator on the time-divided basis. Further, attack and decay coefficients are stored in the envelope memory by higher and lower order bits of the same address, respectively, and the contents of the higher and lower order bits are selectively read out.
