Abstract
In a wave generator for an electronic musical instrument, a plurality of sampling values of a musical tone waveform having a given envelope are simultaneously carried out in a time division system according to the musical tone waveform calculation sequence which can be varied as required; more specifically, calculation for generating a musical tone waveform is carried out while advancing phase, the envelope given to the musical tone waveform is divided into plural segments whose time intervals can be changed as desired, and phase increment values are set for the segments thus obtained while increment values are set for the phase increment values, respectively, these values being accumulated to carry out the calculation of the musical tone waveform, whereby the musical tone waveform and its envelope are varied intricately to produce musical tones rich in natural feeling.
