Abstract:
1. A data communication apparatus that transmits MIDI data to a data receiving apparatus having a processing section that processes MIDI data at the rate of a reference clock according to MIDI Standards, via a communication path which has a higher transfer rate than the rate of the reference clock according to MIDI Standards, comprising: a data generating device that generates MIDI data at a higher rate than the rate of the reference clock according to MIDI Standards, and outputs the generated MIDI data; an output controller that has a clock generator generating a clock at the rate of the reference clock according to MIDI Standards, and controls time intervals at which the generated MIDI data is outputted from said data generating device, based on the clock generated by said clock generator; and a transmission device that transmits the outputted MIDI data to the communication path having the higher transfer rate than the rate of the reference clock according to MIDI Standards; wherein when outputting the MIDI data periodically by said data generating device is interrupted, and then resumed, said output controller controls said data generating device to immediately output first MIDI data to be output after interruption of outputting the MIDI data without being based on the clock generated by said clock generator.
