Musical performance apparatus and musical performance program
First Claim
1. A musical performance apparatus comprising:
- waveform data storing portion storing a plurality of basic waveform data sets indicative of waveforms of a plurality of different tones corresponding to a plurality of different digital signals and containing frequency components included in a predetermined frequency band; and
reproducing portion that selects two or more tones from among the plurality of tones in accordance with a control signal for controlling an external apparatus, reads out the basic waveform data indicative of the selected tones from the waveform data storing portion, and reproduces a control tone that corresponds to the control signal,wherein the control tone includes a combination of the selected tones.

Abstract
The musical performance apparatus has a ROM 17cwhich 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.
