ABSTRACT:
A music play apparatus has a data supply unit for providing performance data and initialization data associated to a desired music piece, and a sound source unit for reproducing the music piece according to the performance data and the initialization data. The data supply unit has a sequencer device that time-sequentially processes a plurality of performance data according to a predetermined order of music pieces, and a transmitter device that transmits each of the processed performance data. The transmitter device is operative when transmitting the performance data of a preceding music piece to interlace the initialization data of a succeeding music piece into the performance data of the preceding music piece by multiplexing operation. The sound source unit has a receiver device that successively receives the performance data in the predetermined order. The receiver device operates when receiving the performance data of the preceding music piece to separate therefrom the initialization data of the succeeding music piece by demultiplexing operation. A memory device temporarily stores the separated initialization data of the succeeding music piece while the preceding music piece is being reproduced. A tone generator device is customized to the succeeding music piece by the stored initialization data immediately after the reproduction of the preceding music piece is finished, and then readily starts the reproduction of the succeeding music piece according to the performance data thereof which is fed from the receiver device to thereby ensure substantially non-interruptive reproduction of the preceding music piece and the succeeding music piece.
