1. Section 1. Receive data
■ Channel Voice Messages
● Note off
Status 2nd byte 3rd byte
8nH kkH vvH
9nH kkH 00H
n = MIDI channel number: 0H-FH (ch.1-ch.16)
kk = note number: 00H-7FH (0-127)
vv = note off velocity: 00H-7FH (0-127)
* For Drum Parts, these messages are received when Rx.NOTE OFF = ON for each Instrument.
● Note on
Status 2nd bytes 3rd byte
9nH kkH vvH
n = MIDI channel number: 0H-FH (ch.1-ch.16)
kk = note number: 00H-7FH (0-127)
vv = note on velocity: 01H-7FH (1-127)
* Not received when Rx.NOTE MESSAGE = OFF. (Initial value is ON)
* For Drum Parts, not received when Rx.NOTE ON = OFF for each Instrument.
● Polyphonic Key Pressure
Status 2nd bytes 3rd byte
AnH kkH vvH
n = MIDI channel number: 0H-FH (ch.1-ch.16)
kk = note number: 00H-7FH (0-127)
vv = key pressure: 00H-7FH (0-127)
* Not received when Rx.POLY PRESSURE (PAf) = OFF. (Initial value is ON)
* The resulting effect is determined by System Exclusive messages. With the initial settings,
there will be no effect.
● Control Change
* When Rx.CONTROL CHANGE = OFF, all control change messages except for Channel Mode
messages will be ignored.
* The value specified by a Control Change message will not be reset even by a Program Change,
etc.
❍ Bank Select (Controller number 0, 32)
Status 2nd bytes 3rd byte
BnH 00H mmH
BnH 20H llH
n = MIDI channel number: 0H-FH (ch.1-ch.16)
mm, ll = Bank number: 00H, 00H-7FH, 7FH (bank.1-bank.16384),
Initial Value = 00 00H (bank.1)
* Not received when Rx.BANK SELECT = OFF.
* “Rx.BANK SELECT” is set to OFF by “GM1 System On,” and Bank Select message will be ignored.
* “Rx.BANK SELECT” is set to ON by “GM2 System On.”
* “Rx.BANK SELECT” is set to ON by power-on Reset or by receiving “GS RESET.”
* When Rx.BANK SELECT LSB = OFF, Bank number LSB (llH) will be handled as 00H regardless of
the received value. However, when sending Bank Select messages, you have to send both the
MSB (mmH) and LSB (llH, the value should be 00H) together.
* Bank Select processing will be suspended until a Program Change message is received.
* The GS format “Variation number” is the value of the Bank Select MSB (Controller number 0)
expressed in decimal.
* Some other GS devices do not recognize the Bank Select LSB (Controller number 32).

❍ NRPN MSB/LSB (Controller number 98, 99)
Status 2nd bytes 3rd byte
BnH 63H mmH
BnH 62H llH
n = MIDI channel number:0H-FH (ch.1-ch.16)
mm = upper byte (MSB) of the parameter number specified by NRPN
ll = lower byte (LSB) of the parameter number specified by NRPN
* Rx.NRPN is set to OFF by power-on reset or by receiving “GM1 System On” or “GM2 System
On,” and NRPN message will be ignored. NRPN message will be received when Rx.NRPN = ON,
or by receiving “GS RESET.”
* The value set by NRPN will not be reset even if Program Change or Reset All Controllers is
received.
**NRPN**
The NRPN (Non Registered Parameter Number) message allows an extended range of control
changes to be used.
To use these messages, you must first use NRPN MSB and NRPN LSB messages to specify the
parameter to be controlled, and then use Data Entry messages to specify the value of the specified
parameter. Once an NRPN parameter has been specified, all Data Entry messages received on that
channel will modify the value of that parameter. To prevent accidents, it is recommended that you
set RPN Null (RPN Number = 7FH/7FH) when you have finished setting the value of the desired
parameter. Refer to Section 4. Supplementary material “Examples of actual MIDI messages”
<Example 4> (p. 14). On the GS devices, Data entry LSB (llH) of NRPN is ignored, so it is no problem
to send Data entry MSB (mmH) only (without Data entry LSB).
On this instrument, NRPN can be used to modify the following parameters.

* Parameters marked “relative change” will change relatively to the preset value(40H). Even
among different GS devices, “relative change” parameters may sometimes differ in the way the
sound changes or in the range of change.
* Parameters marked “absolute change” will be set to the absolute value of the parameter,
regardless of the preset value.
* Data entry LSB (llH) is ignored.
❍ RPN MSB/LSB (Controller number 100, 101)
Status 2nd bytes 3rd byte

BnH 64H llH
n = MIDI channel number: 0H-FH (ch.1-ch.16)
mm = upper byte (MSB) of parameter number specified by RPN
ll = lower byte (LSB) of parameter number specified by RPN
* Not received when Rx.RPN = OFF. (Initial value is ON)
* The value specified by RPN will not be reset even by messages such as Program Change or
Reset All Controller.
**RPN**
The RPN (Registered Parameter Number) messages are expanded control changes, and each
function of an RPN is described by the MIDI Standard.
To use these messages, you must first use RPN MSB and RPN LSB messages to specify the
parameter to be controlled, and then use Data Entry messages to specify the value of the specified
parameter. Once an RPN parameter has been specified, all Data Entry messages received on that
channel will modify the value of that parameter. To prevent accidents, it is recommended that you
set RPN Null (RPN Number = 7FH/7FH) when you have finished setting the value of the desired
parameter.Refer to Section 4. “Examples of actual MIDI messages” <Example 4> (p. 14).
On this instrument, RPN can be used to modify the following parameters.

Non-realtime Messages (7EH) and Universal Realtime Messages (7FH).

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.

This instrument can receive the various parameters using System Exclusive messages.
The exclusive message of GS format data has a model ID of 42H and a device ID of 10H (17), and it
is common to all the GS devices.

This map indicates address, size, Data (range), Parameter, Description, and Default Value of parameters which can be transferred using and “Data set 1 (DT1).”
All the numbers of address, size, Data, and Default Value are indicated in 7-bit Hexadecimal-form.
■ Address Block map
An outlined address map of the Exclusive Communication is as follows;
Address (H) Block

There are two ways in which GS data is transmitted: Individual Parameter Transmission in which individual parameters are transmitted one by one, and Bulk Dump Transmission in which a large amount of
data is transmitted at once.

■ Individual Parameters
Individual Parameter Transmission transmits data (or requests data) for one parameter as one exclusive message (one packet of “F0 ..... F7”).
In Individual Parameter Transmission, you must use the Address and Size listed in the following “Parameter Address Map.” Addresses marked at “#” cannot be used as starting addresses.
