<P>PROBLEM TO BE SOLVED: To specify the pitch of a note to be made to output from a sound source according to the operation of an electronic wind instrument. <P>SOLUTION: A table including a pair of binary data indicating an operator ought to be on, an operator ought to be off and an operator which may be either of them as different bit patterns is prepared and the binary data pairs of the table are sequentially collated based on the binary data obtained by detecting the state of each operator so that the pitch of the note is thereby unequivocally specified. <P>COPYRIGHT: (C)2007,JPO&INPIT |
