A pitch conversion part 4 converts the input pitch into a 1st output pitch suitable to the chord information inputted from a chord information supply part 2 prior to the inputted musical performance information when the musical performance information is inputted from a musical performance information supply part 1, and converts the input pitch into a 2nd output pitch matching new chord information when the new chord information is inputted from the chord information supply part 2 when the start of sounding of the input pitch is already indicated with the inputted musical performance information and a sound is being generated. <P>COPYRIGHT: (C)2004,JPO |
