Abstract

PURPOSE: To generate the musical tone sounds, to which the aging of the harmonic construction is imparted, by dividing the one cycle waveform of a key depression tone into a plurality of blocks thereby to control the rising and breaking amplitude and curve of the waveform of each block.
CONSTITUTION: In response to the counted step signals of a tone clock frequency control circuit 2 according to the key depression tone code from a tone input code register 1, the one cycle of the musical sound waveform corresponding to the tone is divided by a waveform synchronous counting circuit into a plurality of blocks so that the waveform codes of each block are fed through a decoder 4 thereby to address a program designating unit 5. This unit 5 generates the coefficient value including the up and down for the waveform amplitude control of each block thereby to impress it upon a multiplying circuit 6. On the other hand, the circuit 6 is supplied from an envelope counter 7 with an envelope coefficient according to the time laspe of the key depression and to the volume code. As a result, the circuit 6, an adder 8 and a summing device 9 simultaneously generate the musical sounds of different waveforms, and the chords to which the aging change of the harmonic construction are effectively imparted can be generated with the use of a simple construction.
