Abstract

PURPOSE: To change the harmonic overtone structure of musical tones with time by using a waveform indicating means and a digital control means.
CONSTITUTION: A sound volume control part II and a frequency control part I which corresponds to the frequency sounds of operating keys are connected to the musical tone waveform forming part III consisting of a waveform indicating part 9, waveform output control part 10, addition-substraction control part 11, addition- subtraction part 12 and comparator part 13. As a result, the outputs of a step address counter part 4 and amplitude value indicating and counting part 8 are inputted to the comparator part 13, waveform output control part 10 and addition- substraction control part 11 and at the same time the outputs of a state memory part 5 are inputted to the waveform output control part 10, then the reference waveforms indicated by the waveform indicating part 9 are gradually deformed in the respective periods of increase, transform and decrease, whereby the intended object is achieved.
