Abstract
A global envelope is input by a user and stored in a global envelope memory. At the respective envelope-controlled sine wave generators are generated envelope functions of the respective orders by modifying the input global envelope. The envelopes of component wave signals of a plurality of orders are independently controlled by the envelope functions having the respective orders in the generators, and a musical tone signal is synthesized by combining the envelope-controlled component wave signals.
