MIDI data words are supplied to a data transmitter of a music data transmitting system at irregular intervals; when the data transmitter receives each of the MIDI data words, the data transmitter checks the status byte to see whether or not the status byte contains a data nibble identical with a synchronous data nibble, replaces the data nibble with another data nibble with positive answer for producing a quasi MIDI data word, supplements synchronous data nibble or nibbles between the quasi MIDI data words, and modulates a data stream containing the quasi MIDI data words and the synchronous data nibbles for synchronously transmitting the modulated signal to a data receiver of the music data transmitting system at high transfer efficiency; when the modulated signal reaches the data receiver, the data receiver demodulates the received signal, eliminates the synchronous data nibbles from the data stream, and converts the quasi MIDI data words to the MIDI data words.
