●All Notes O (Controller Number 123)

Status 2nd byte 3rd byte
BnH 7BH 00H
n = MIDI channel number: 0H-FH (ch.1-ch.16)
* When All Notes O is received, all notes on the corresponding channel will be
turned o . However if Hold 1 or Sostenuto is ON, the sound will be continued until
these are turned o .

●OMNI OFF (Controller Number 124)

Status 2nd byte 3rd byte
BnH 7CH 00H
n = MIDI channel number: 0H-FH (ch.1-ch.16)
* The same processing will be carried out as when All Notes O is received.

●OMNI ON (Controller Number 125)

Status 2nd byte 3rd byte
BnH 7DH 00H
n = MIDI channel number: 0H-FH (ch.1-ch.16)
* OMNI ON is only recognized as “All notes o ”; the Mode doesn’t change (OMNI OFF
remains).

●MONO (Controller Number 126)

Status 2nd byte 3rd byte
BnH 7EH mmH
n = MIDI channel number: 0H-FH (ch.1-ch.16)
mm = mono number : 00H-10H (0-16)
* The same processing will be carried out as when All Sounds O and All Notes O is
received, and the corresponding channel will be set to Mode 4 (M = 1) regardless of
the value of “mono number.”

●POLY (Controller Number 127)

Status 2nd byte 3rd byte
BnH 7FH 00H
n = MIDI channel number: 0H-FH (ch.1-ch.16)
* The same processing will be carried out as when All Sounds O and All Notes O is
received, and the corresponding channel will be set to Mode 3.
■System Realtime Message

●Active Sensing

Status
FEH
* When Active Sensing is received, the unit will begin monitoring the intervals of
all further messages. While monitoring, if the interval between messages exceeds
420 ms, the same processing will be carried out as when All Sounds O , All Notes
O and Reset All Controllers are received, and message interval monitoring will be
halted.
■System Exclusive Message
Status 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).
dd,...,ee = data: 00H-7FH (0-127)
F7H: EOX (End Of Exclusive)
The System Exclusive Messages received by this instrument are; messages related to
mode settings, Universal Realtime System Exclusive messages, Universal Non-
realtime System Exclusive messages and Data Set (DT1).

●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 initial state (General MIDI System-Level 1).
Status Data byte Status
F0H 7EH, 7FH, 09H, 01H F7H
Byte Explanation
F0H Exclusive status
7EH ID number (Universal Non-realtime Message)
7FH Device ID (Broadcast)
09H Sub ID#1 (General MIDI Message)
01H Sub ID#2 (General MIDI 1 On)
F7H EOX (End Of Exclusive)
* When this message is received, Rx. BANK SELECT will be OFF and Rx. NRPN will be
OFF.
* There must be an interval of at least 50 ms between this message and the next.

❍ GM2 System On

This is a command message that resets the internal settings of the unit to the General
MIDI initial state (General MIDI System-Level 2).
Status Data byte Status
F0H 7EH 7FH 09H 03H F7H
Byte Explanation
F0H Exclusive status
7EH ID number (Universal Non-realtime Message)
7FH Device ID (Broadcast)
09H Sub ID#1 (General MIDI Message)
03H Sub ID#2 (General MIDI 2 On)
F7H EOX (End Of Exclusive)
* When this message is received, this instrument will be able to receive the messages
speci ed by General MIDI 2, and use the General MIDI 2 soundmap.
* There must be an interval of at least 50 ms between this message and the next.
