Abstract
In executing a music performance on the basis of supplied performance data, a feeling of swing can be imparted to the performance by delaying tone-generation start time of a tone, based on the performance data, at each predetermined beat such as upbeat. In this case, if an original tone-generation end time of the tone to be delayed is ahead of tone-generation start time of a next tone, control is executed to automatically change a duration of the tone in such a manner that actual tone-generation end time of the delayed note comes ahead of the tone-generation start time of the next tone. In this manner, the delay control can be properly executed on staccato performance data without losing characteristics of staccato. If, on the other hand, the original tone-generation end time of the tone to be delayed is behind the tone-generation start time of the next tone, control is executed to automatically change the duration of the tone in such a manner that the actual tone-generation end time of the delayed tone comes behind the tone-generation start time of the next tone. In this manner, the delay control can be properly executed on legato performance data without losing characteristics of legato.
