Data byte Status
F0H iiH, ddH, ......,eeH F7H
F0H: System Exclusive Message status
ii = ID number: an ID number (manufacturer ID) to indicate the manufacturer whose
Exclusive message this is. Roland’s manufacturer ID is 41H.
ID numbers 7EH and 7FH are extensions of the MIDI standard; Universal Non-realtime
Messages (7EH) and Universal Realtime Messages (7FH).

System Exclusive messages related to mode settings
These messages are used to initialize a device to GS or General MIDI mode, or change the
operating mode. When creating performance data, a “GM1 System On” message should be
inserted at the beginning of a General MIDI 1 score, a “GM2 System On” message at the
beginning of a General MIDI 2 score, and a “GS Reset” message at the beginning of a GS
music data. Each song should contain only one mode message as appropriate for the type of
