Abstract
A karaoke apparatus is constructed to reproduce a karaoke music piece according to karaoke data composed of setup data and performance data. The karaoke apparatus utilizes a pair of sound source devices each of which is initialized according to the setup data and is then operated to reproduce the karaoke music piece according to the performance data so that the sound source devices can be alternately operated with each other to successively reproduce a plurality of karaoke music pieces. In the karaoke apparatus, a first control device operates when one of the sound source devices reproduces a preceding one of the karaoke music pieces for providing the other of the sound source devices with setup data contained in karaoke data corresponding to a succeeding one of the karaoke music pieces so as to initialize the other sound source device before the one sound source device finishes reproduction of the preceding karaoke music piece. Further, a second control device operates when the one sound source device finishes the reproduction of the preceding karaoke music piece for providing the other sound source device with performance data of the succeeding karaoke music piece so as to operate the other sound source device to reproduce the succeeding karaoke music piece immediately after the one sound source device finishes the reproduction of the preceding karaoke music piece.
