<P>PROBLEM TO BE SOLVED: To change volume balance between a plurality of musical sound signals according to operation of a volume control operator. <P>SOLUTION: Musical sound signal creation sections 17a to 17h create a plurality of sequences of musical sound signals according to performance operation of an upper keyboard 11, a lower keyboard 12 and a foot keyboard 13. Volume characteristic converting sections 30a to 30h foot convert a pressing amount of an expression pedal 14 to a plurality of volume control values with different conversion characteristics respectively. Multiplication sections M1 to M8 independently control volume change characteristics of the plurality of sequences of musical sound signals for operation of the expression pedal 14, by multiplying the plurality of sequences of musical sound signals by the plurality of volume control values respectively. <P>COPYRIGHT: (C)2008,JPO&INPIT |
