PROBLEM TO BE SOLVED: To prevent incongruous sense due to an attack sound in retrigger processing of an automatic accompanying device. SOLUTION: A ch is set in 1 (S420), and when the ch is turned on (S421: YES), a sound is erased (S422). The note data are read in from a note data storage memory, and its pitch is converted according to a set code (S423), and the key number of the note data is updated S424). When the tone color of the note data is an attenuated sound (S425: YES), the velocity of the note data is re-written to a value multiplying the velocity by 0.7 (S426), and the generation of a waveform signal corresponding to the note data is instructed to a sound source 28 (S427). Since the intensity is weakened by the velocity change (S426) when the tone color is the attenuated sound, the matter that the incongruous sense is sensed because of the attack sound of the attenuated sound is eliminated. |
