摘要： Left- and right-hand keystroke windows X.sub.L and X.sub.H are decided in accordance with the positions of player's left and right hands pressing keys. When the number of pressed keys in either one of the windows X.sub.L and X.sub.H are larger than a predetermined value, that window is decided to be used as a chord identifying window, and on the basis of a combination of pressed keys in the chord identifying window, an accompaniment chord is decided for automatic accompaniment.

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.
