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
data. (Do not insert two or more mode setting messages in a single song.)
"GM System On" uses Universal Non-realtime Message format. "GS Reset" uses Roland
system Exclusive format "Data Set 1 (DT1)."
GM1 System On
This is a command message that resets the internal settings of the unit to the General MIDI 1
initial state. After receiving this message, the SC-8820 will automatically be set to the proper
condition for correctly playing a General MIDI score.
