摘要： The musical performance apparatus has a ROM 17c which stores sample values obtained by sampling a plurality of tones corresponding to a plurality of digital signals each having a different bit pattern so that the sample values of waveforms of the tones will correspond to sampling periods. In the ROM 17c, the sample values are stored in association with addresses. The musical performance apparatus also has a computer portion 17 and a tone generation circuit 15 which select one or more tones from the plurality of tones in accordance with musical score data SD formed of a plurality of bits, read out waveform data indicative of the selected tones from the ROM 17c, and reproduce the selected tones. The plurality of tones are formed of frequency components included in a certain high frequency band.
