Vibrato Depth (Controller Number 77)
Status
2nd byte
3rd byte
BnH 4DH vvH
n = MIDI channel number:
0H–FH (ch.1–ch.16)
vv = Vibrato Depth Value (relative change):
00H–7FH(-64–0–+63),
Initial Value = 40H (no change)
* Not received when Rx. Vibrato Depth = OFF. (Initial value is ON)
* Some Tones will not exhibit any change.

Vibrato Delay (Controller Number 78)
Status
2nd byte
3rd byte
BnH 4EH vvH
n = MIDI channel number:
0H–FH (ch.1–ch.16)
vv = Vibrato Delay value (relative change): 00H–7FH(-64–0–+63),
Initial value=40H (no change)
* Not received when Rx. Vibrato Delay = OFF. (Initial value is ON)
* Some Tones will not exhibit any change.

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.

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.

Effect 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 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>. On the GS devices, Data entry LSB (llH) of NRPN (controller
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.
