Abstract
Data representing a pitch is extracted from an input waveform signal and a musical tone having a corresponding tone pitch is generated. By chromatically designating a tone pitch, a musical tone having a tone pitch of a semitone unit is generated from a sound source circuit at the starting of the input waveform signal. After tone generation is started, in the system for updating a tone pitch having an interval of less than a semitone interval, a musical tone is generated in accordance with various performances. Therefore, a musical interval after tone generation is started can be clearly recognized, thus obtaining an excellent musical performance effect.
