Gm System Off; System Realtime Message; Active Sensing; System Exclusive Message - Roland DP990F Implementation

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).
●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 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)

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

Status Data byte
F0H iiH, ddH, ......, eeH
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 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). After receiving this
message, this instrument will automatically be set to the proper condition for
correctly playing a GM score.
