PROBLEM TO BE SOLVED: To avoid an influence of chattering while suppressing a delay of tone control by easy processing.SOLUTION: Each switch sw of an operation sensor 21 generates an on/off-event according to the reciprocating operation of a performance operator 1. In a reciprocating process where the performance operator 1 is displaced from an initial position to a pressing position and returns, an event generation order is determined as A ON →B ON →C ON →C OFF →B OFF →A OFF. Event data ev are stored in a RAM 7 in an order of generation in a time series. When the event type K of the latest event is C ON and the event data ev whose note data Note are the same as those of the latest event exists in an ev register, a performance signal of the note-on corresponding to the latest event (C ON) is generated as long as an event type K of the event data ev immediately before the latest event (C ON) is "B ON". |
