ll: 00H - 7FH (0 - 100 cents), 100/128 Cent/Value
7FH 7FH --- --- RPN null
Set condition where RPN and NRPN are unspecified. The
data entry messages after set RPN null will be ignored. (No
Data entry messages are required after RPN null). Settings
already made will not change.

EnH llH mmH
n = MIDI channel number: 0H - FH (ch.1 - 16)
mm, ll = Pitch Bend value: 00 00H - 40 00H - 7F 7FH (-8192 - 0 - +8191)
* Not transmitted when System: P.Bend TxRx = OFF. (Initial value is ON)
■System Realtime Messages
●Timing Clock
Status
F8H
* Not transmitted when System: Clock Tx = OFF. (Initial value is ON)
●Song/Style Start
Status
FAH
* Not transmitted when System: StartStop Tx = OFF. (Initial value is ON)
* This message is transmitted when the internal song/style player is started.
●Song Continue
Status
FBH
* Not transmitted when System: StartStop Tx = OFF. (Initial value is ON)
* This message is transmitted when the internal song player is started not from the
beginning.
* Transmitted only in Song Mode.
●Song/Style Stop
Status
FCH
* Not transmitted when System: StartStop Tx = OFF. (Initial value is ON)
* This message is transmitted when the internal song/style player is stopped.
●Active Sensing
Status
FEH
* This message is transmitted constantly at intervals of approximately 250 msec.
■System Common Message
●Song Position Pointer
Status 2nd byte 3rd byte
F2H llH hhH
ll = song position LSB: 00H - 7FH
hh = song position MSB: 00H - 7FH
* Not transmitted when System: SongPos TxRx = OFF. (Initial value is ON)
* Transmitted only in Song Mode.
■System Exclusive Messages
●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)”.
