Portamento Control (Controller Number 84)

Status

2nd byte

3rd byte

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.

Eff ect 1 (Reverb Send Level) (Controller Number 91)

Status

2nd bytes

3rd byte

BnH 5BH vvH

n = MIDI channel number:

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

vv = Control value :

00H-7FH (0-127), Initial Value = 28H (40)

* This message adjusts the Reverb Send Level of each Part.

Eff ect 3 (Chorus Send Level) (Controller Number 93)

Status

2nd byte

3rd byte

BnH 5DH vvH

n = MIDI channel number:

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

vv = Control value:

00H-7FH (0-127), Initial Value = 00H (0)

* This message adjusts the Chorus Send Level of each Part.

NRPN MSB/LSB (Controller Number 98, 99)

Status

2nd byte

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 specifi ed by NRPN

ll = lower byte (LSB) of the parameter number specifi ed 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 fi rst 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 specifi ed parameter. Once an NRPN parameter has been

specifi ed, 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 fi nished setting the value of the desired

parameter. Refer to Section 4. Supplementary material “Examples of actual MIDI

messages” <Example 4>. On the GS devices, Data entry LSB (llH) of NRPN (contrpller

number 38) is ignored, so it is no problem to send Data entry MSB (mmH) only

without Data entry LSB (controller number 6).

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 diff erent GS devices, “relative change” parameters may sometimes

diff er 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.
