A waveform memory for storing data of musical tone waveforms can be mounted in and dismounted from an electronic musical instrument body. The waveform memory is thus replaceable, permitting the sounding of tones with various varieties. In addition, if musical tone waveform data corresponding to a tone designated for sounding is not stored in the memory, it is automatically loaded in the memory, thus permitting automatic sounding of tones to be requested. |
