Interchange format of voice data in music file

摘要

A music apparatus has a data storage, a controller and a sound generator for reproducing a music sound and a voice sound. The data storage stores a music data file containing a music part and a voice part, the music part containing a sequence of music generation events effective to instruct generation of the music sound, the voice part containing voice reproduction sequence data composed of a combination of voice reproduction event data and duration data, the voice reproduction event data instructing reproduction of a sequence of voice events, the duration data specifying a timing of effecting a voice event in terms of a duration time measured from another voice event preceding to the voice event. The controller reads out the music data file from the data storage. The sound generator operates based on the music part contained in the read music data file for generating the music sound representative of the sequence of the music events, and operates based on the voice part contained in the read music data file for generating the voice sound representative of the sequence of the vice events, thereby mixing and outputting the music sound and the voice sound.
