Abstract
Plural channels of tone generation capable of selectively generating plural kinds of waveshape signals are provided. A waveshape signal to be selected in each of the channels is designated in accordance with the tone pitch or tone range of a tone to be generated and waveshape signals which differ from each other between the channels are respectively generated. The different waveshape signals of the respective channels are weighted by scaling parameters according to the tone pitch. A circuit capable of providing the waveshape signal with amplitude envelopes which differ from each other between the channels is further provided and selection between imparting of such envelopes and weighting in accordance with the scaling parameter is made in response to a tone color. A plurality of tone synthesis systems having the tone synthesis function described may be provided and tone signals obtained in the respective systems may be added together.
