Abstract
PURPOSE: To obtain an effective timbre, by providing a musical tone waveform indication means to indicate the rise and fall of the waveform in each block by + or - of integer times of control value of the sound volume control means.
CONSTITUTION: Differential coefficient value and +, - indication signals specified in each block address by a waveform program specifying part 5 are outputted sequentially in synchronism with the block address signal from a decoder 4 and are supplied into a multiplication circuit 6. In this multiplication circuit 6 is supplied a control value of a sound volume curve making counter 7 which digitally controls the sound volume controlling to increase or decrease the performance sound volume along with the time elapse from the time of operation of performance key. Finally, the control values are multiplied in synchronism with the block address according to the differential coefficient value and the +, - indications of the waveform program specifying part 5.
