ABSTRACT:
An electronic musical instrument has a waveform memory and a tone generator. The waveform memory has a plurality of storage areas, each of which is capable of storing a fixed bit-width data. In the case where the bit-width of the waveform data corresponding to a musical tone waveform is different from the bit-width of the data which can be stored in each storage area, the whole waveform data corresponding to the musical tone waveform are stored in the waveform memory so as not to allow the generation of empty areas which store no data. The waveform data may be divided if necessary and the divided parts of the waveform data are stored in some storage areas of the waveform memory. The tone generator reads out the data corresponding to a desired musical tone which is to be generated and which are stored in the waveform memory, and determines the waveform data from the read out data based on the bit-width of the waveform data of the desired musical tone, and generates the musical tone based on the determined waveform data.
