All Notes Off (Controller Number 123)

Status

2nd byte

3rd byte

BnH 7BH 00H

n = MIDI channel number:

0H-FH (ch.1-ch.16)

* When All Notes Off is received, all notes on the corresponding channel will be

turned off . However if Hold 1 or Sostenuto is ON, the sound will be continued until

these are turned off .

3rd byte

BnH 7CH 00H

* The same processing will be carried out as when All Notes Off is received.

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 off ”; the Mode doesn’t change (OMNI OFF

remains).

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 Off and All Notes Off 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 Off and All Notes Off 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 Off , All Notes

Off and Reset All Controllers are received, and message interval monitoring will be

halted.

System Exclusive Message

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:

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).
