ABSTRACT:
A waveform generating apparatus for generating waveforms which can be suitably employed in electronic musical instruments. The waveform generating apparatus calculates and generates regenerated sample data of a regenerated waveform having a desired pitch in synchronization with a constant regeneration sampling interval based on basic sample data which are sampled from a basic waveform by a predetermined basic sampling interval. The apparatus includes a phase generator, an operation mode control circuit and an interpolating circuit. The phase generator generates phase data which designates a phase of basic waveform. The operation mode control circuit supplies a calculation designating data. The interpolating circuit calculates regenerated sample data on the basis of basic sample data and phase data. Wherein, the method of the interpolation which is performed by the interpolating circuit is altered in response to calculation designating data. Thus, waveform can be regenerated accurately and with high fidelity over a wide range of pitches.
