<P>PROBLEM TO BE SOLVED: To control key scaling without losing a music stream nor unification. <P>SOLUTION: A CPU 1 performs arithmetic processing for key scaling by storing a key number input by playing a keyboard 9 through a key scanner 6 in an event ring buffer of a RAM 4, setting a parameter of sound generation for the input key number, selecting a plurality of past key numbers stored in the event ring buffer, and varying the input key number by the current playing based upon history information of a plurality of key numbers of past playing for which the set parameter of sound generation was selected. <P>COPYRIGHT: (C)2007,JPO&INPIT |
