Abstract
In a multi-access local area network, a plurality of stations employing a predetermined protocol (e.g., a protocol based on a CSMA/CD system) are linked together by a bus. In order to transmit MIDI data in the multi-access local area network, another station employing a certain protocol which is suitable for transmitting the MIDI data is further provided and is designed to perform a frequency modulation by a unit of word. The protocol employed by another station defines a specific frame form which is based on a start-stop system. The specific frame form contains a sequence of a preamble, a start bit, a data portion and a stop bit. An optimum bit pattern which is suitable for the transmission of the MIDI data is selected for the preamble.
