ABSTRACT:
A musical tone-generating method and apparatus therefor are provided. Musical tones are generated by reading waveform data from a waveform table at a predetermined sampling frequency and carrying out arithmetic operations on the waveform data read from the waveform table to generate musical tone waveform samples, by the use of a processing unit. A first sampling frequency or a second sampling frequency lower than the first sampling frequency is selected as the predetermined sampling frequency. Interpolation of the waveform data read from the waveform table is effected by a second interpolation method which is lower in accuracy than a first interpolation method employed when the first sampling frequency is used, or alternatively the interpolation is inhibited, when the second sampling frequency is selected as the predetermined sampling frequency.
