ABSTRACT:
An electronic musical instrument includes a performance operating member, a performance operation detection unit, a self vibration detection data forming unit, a tone generation control unit, and a tone signal generator. The performance operation detection unit forms performance operation detection data corresponding to an operation amount of the performance operating member. When the performance operation detection data of the performance operating member is obtained, the self vibration detection data forming unit forms self vibration detection data determined by a performance operation mounted based on previous performance operation detection data obtained by a previous performance operation of the performance operating member and by a first lapse time interval from when previous performance operation detection data were obtained until a present time. The tone generation control unit compares the performance operation detection data at the present time with the self vibration detection data, and forms, based on the comparison result, tone generation data representing whether or not tone generation is made. The tone signal generator performs a tone generation operation of a musical tone in response to the tone generation data.
