Method and apparatus for automatically producing alterable rhythm accompaniment using conversion tables

摘要

A rhythm pattern memory having rhythm patterns stored therein, the rhythm patterns being composed of pattern data corresponding to the types of percussion instruments, and a conversion table memory having a plurality of conversion tables for altering sound data each representative of a desired percussion instrument sound to sound data representative of an other percussion instrument sound are provided. A desired percussion instrument sound data in the rhythm pattern selected from the rhythm pattern memory by a rhythm pattern selector is altered to a desired percussion sound data according to the conversion table selected from the conversion table memory by the conversion table selector, and the resulting percussion sound data is converted by a sound source to the corresponding percussion sound signal to be output.
