Abstract
A karaoke apparatus operates in response to a song request for sounding an automatic accompaniment mixed with a singing voice to produce a karaoke performance involving an additional effect. The karaoke apparatus is supplied with a composite song data containing an accompaniment event data and an additional effect event data. A multimedia sequencer time-sequentially processes the supplied composite song data to synchronously feed a train of the accompaniment event data and another train of the additional effect event data in parallel manner with one another. A tone generator operates based on the fed accompaniment event data for generating an automatic accompaniment so as to produce a karaoke performance. An additional effect equipment is controlled by the fed additional effect event data for imparting an additional effect to the karaoke performance in matching with time-sequential progression thereof.
