Abstract
Abstract Disclosed is a karaoke authoring apparatus for mixing or authoring karaoke music data based on an electronic music sound source. The invention can analyze chronologically, in a sound reproduction block, the musical performance data expressed by a code such as MIDI code and has a pre-inserted event code, and will generate an interrupt in a timer circuit at a time interval based on the tempo instruction on the code. The invention can also acquire, as an individual file at the timing of the event code, an integrated value given by the timer circuit in accordance with the type of event, and combine and arrange these files in chronological order to calculate a time difference between consecutive event codes, for producing time data. The authored data allows color turning of the words of the music, page turning, presentation of the title of the music and a video image update which is performed accurately to the timing as planned, in synchronism with the musical performance.
