VE-GS Pro MIDI Implementation
1
The VE-GS Pro implements additional functionality and parameters over and above the
SC-88, which itself was an expansion of the GS sound source format. These functions and
parameters are marked by a [Pro] symbol. If MIDI messages marked by a [Pro] symbol are
transmitted to another GS format sound source or to the SC-88, those messages may not
be recognized. Also, functions and parameters which were added to the SC-88 over and
above previous GS format sound sources are marked by an [88] symbol.
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.
* The velocity values of Note Off messages are ignored.
● Note on
Status 2nd byte 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 byte 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) [88]
Status 2nd byte 3rd byte
BnH 00H mmH
BnH 20H llH
n = MIDI channel number : 0H-FH (ch.1-ch.16)
mm = Bank number MSB : 00H-7FH (GS Variation number 0 - 127), Initial Value
= 00H
ll = Bank number LSB : 00H - 03H (MAP), Initial Value = 00H
* Not received when Rx.BANK SELECT = OFF. "Rx.BANK SELECT" is set to OFF by "Turn
General MIDI System On," and set to ON by "GS RESET." (Power-on default value is ON.)
* When Rx.BANK SELECT LSB = OFF, Bank number LSB 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.
* The VE-GS Pro recognizes the Bank Select LSB (Controller number 32) as a flag for
switching between the Native MAP,SC-88MAP and the SC-55MAP. With a Bank Select
LSB of 00H, the map selected by the front panel MAP button will be selected. With a LSB
of 01H, the SC-55MAP will be selected. With a LSB of 02H, the SC-88MAP will be selected. With a LSB of 03H, the Native MAP will be selected.
* The lower byte of the Bank Select message (controller number 32) may not be recognized
by some models of GS instrument.
❍ Modulation (Controller number 1)
Status 2nd byte 3rd byte
BnH 01H vvH
n = MIDI channel number : 0H-FH (ch.1-ch.16)
vv = Modulation depth : 00H-7FH (0-127)
* Not received when Rx.MODULATION = OFF. (Initial value is ON)
* The resulting effect is determined by System Exclusive messages. With the initial settings, this is Pitch Modulation Depth.
❍ Portamento Time (Controller number 5)
Status 2nd byte 3rd byte
BnH 05H vvH
n = MIDI channel number : 0H-FH (ch.1-ch.16)
vv = Portamento Time : 00H-7FH (0-127), Initial value = 00H (0)
* This adjusts the rate of pitch change when Portamento is ON or when using the
Portamento Control. A value of 0 results in the fastest change.
❍ Data Entry (Controller number 6, 38)
Status 2nd byte 3rd byte
BnH 06H mmH
BnH 26H llH
n = MIDI channel number : 0H-FH (ch.1-ch.16)

BnH 54H kkH
n = MIDI channel number : 0H-FH (ch.1-ch.16)
kk = source note number : 00H-7FH (0-127)
* A Note-on received immediately after a Portamento Control message will change continuously in pitch, starting from the pitch of the Source Note Number.
* If a voice is already sounding for a note number identical to the Source Note Number, this
voice will continue sounding (i.e., legato) and will, when the next Note-on is received,
smoothly change to the pitch of that Note-on.
* The rate of the pitch change caused by Portamento Control is determined by the
Portamento Time value.

* NRPN can be received when Rx.NRPN = ON. "Rx.NRPN" is set to OFF by power-on
reset or by receiving "Turn General MIDI System On," and it is set to ON by "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. On the VE-GS Pro, NRPN messages can be used to modify
sound parameters etc.
To use these messages, you must first use NRPN messages (Controller number 98 and
99, their order does not matter) 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 5. Supplementary material "Examples of actual MIDI messages"
<Example 4> (page 123). On the VE-GS Pro, Data entry LSB (Controller number 38) of
NRPN is ignored, so it is no problem to send Data entry MSB (Controller number 6) only
(without Data entry LSB).
On the VE-GS Pro, NRPN can be used to modify the following parameters.

* Parameters marked "relative change" will change relative 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.
* It is not possible to simultaneously use both Chorus Send Level and Delay Send Level on
a single Drum Instrument.

* 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 (Controller number 100 and 101, their order
does not matter) to specify the parameter to be controlled, and then use Data Entry messages (Controller number 6, 38) 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 5. "Examples of actual MIDI messages" <Example 4> (page 123).
On the VE-GS Pro, RPN can be used to modify the following parameters.

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 the VE-GS Pro are; messages related to
mode settings, Universal Realtime System Exclusive messages, Data Requests (RQ1),
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 "Turn General MIDI System On" message should be inserted at the beginning of a General MIDI score, and a "GS Reset" message at the beginning of music files for GS. In the case of data for the SC-88 and for the
VE-GS Pro, we recommend that "System Mode Set" be placed at the beginning of the song
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.)
"Turn General MIDI System On" use Universal Non-realtime Message format. "System
Mode Set" and "GS Reset" use Roland system exclusive format "Data Set 1 (DT1)."
❍ Turn General MIDI System On
This is a command message that resets the internal settings of the VE-GS Pro to the
General MIDI initial state (General MIDI System-Level 1). After receiving this message the
VE-GS Pro, will automatically be set to the proper condition for correctly playing a General
MIDI score.

* There must be an interval of at least 50 ms between this message and the next message.
❍ GS reset
GS Reset is a command message that resets the internal settings of a device to the GS initial state. This message appears at the beginning of music files for GS, and a GS device
that receives this message will automatically be set to the proper state to correctly playback
music files for GS. If the VE-GS Pro is in MODE-1 (single module mode) all 32 Parts will be
initialized. If in MODE-2 (double module mode), only the corresponding 16 Parts will be initialized. In MODE-2 if the receiving MIDI connector for each Part has been changed, this
may affect playback from the other MIDI connector. In this case, first perform initialization
(page 73) before using this command.

● Data transmission
The VE-GS Pro can use Exclusive messages to transmit internal settings to other devices.
There are two types of Exclusive data transmission; Individual Parameter Transmission
(page 113) in which single parameters are transmitted one by one, and Bulk Dump
Transmission (page 121) in which a large amount of data is transmitted at once.
The exclusive message used when transmitting music files for GS format has a model ID of
42H and a device ID of 10H.
❍ Request data 1 RQ1 (11H)
This message requests the other device to send data. The Address and Size determine the
type and amount of data to be sent. There are two types of request; Individual Parameter
Request which requests data for an individual parameter, and Bulk Dump Request which
requests a large amount of data at once. In either case, the "Data Request 1 (RQ1)" message format is used, and the Address and Size included in the message determine the type
and amount of data that is desired.
For Individual Parameter Request, refer to "3. Individual Parameter Transmission" (page
113).
For Bulk Dump Request, refer to "4. Bulk Dump" (page 121).
When a Data Request message is received, if the device is ready to transmit data and if the
address and size are appropriate, the requested data will be transmitted as a "Data Set 1
(DT1)" message. If not, nothing will be transmitted.

There are two ways in which GS data is transmitted: Individual Parameter Transmission
(Section 3 page 113) in which individual parameters are transmitted one by one, and Bulk
Dump Transmission (Section 4 page 121) in which a large amount of data is transmitted at
once.

Section 3. Individual Parameter Transmission
(Model ID=42H)
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.
■ Address Block map
The Address map for Individual Parameter Transmission is as follows.
<Model ID = 42H>
● Port-A
* The blocks displayed in gray cannot be accessed in Mode-1 (Single Module Mode).
* Blocks listed as "#A" are parameter blocks which are common to the entire device in
Mode-1, and valid only for Parts A01 - A16 in Mode-2 (Double Module Mode).
● Port-B
* The blocks displayed in gray cannot be accessed in Mode-1 (Single Module Mode).
* Blocks listed as "#B" are parameter blocks which are common to the entire device in
Mode-1, and valid only for Parts B01 - B16 in Mode-2 (Double Module Mode).
