<P>PROBLEM TO BE SOLVED: To allow even a player having no knowledge about a chord and a rhythm to play suitable automatic accompaniment music. <P>SOLUTION: An automatic accompaniment music data including sounding timing of a musical tone to be sounded is stored in a ROM 22. A CPU 21 calculates time difference between operation timing of a keyboard 11 and the reference timing stored in the ROM 22, and controls the sounding timing of the musical tone in the automatic accompaniment music, which is set for the automatic accompaniment data beforehand, based on the calculated time difference. A sound source section 26 generates a musical tone data of the musical tone of an automatic accompaniment pattern in which the sounding timing is controlled, according to instruction of the CPU 21. <P>COPYRIGHT: (C)2010,JPO&INPIT |
