Portamento (Controller number 65)
Status 2nd bytes
BnH 41H
n = MIDI channel number: 0H-FH (ch.1-ch.16)
vv = Control value: 00H-7FH (0-127) 0-63 = OFF, 64-127 = ON
* Not received when Rx.PORTAMENTO = OFF. (Initial value is ON)
Sostenuto (Controller number 66)
Status 2nd bytes
BnH 42H
n = MIDI channel number: 0H-FH (ch.1-ch.16)
vv = Control value: 00H-7FH (0-127) 0-63 = OFF, 64-127 = ON
* Not received when Rx.SOSTENUTO = OFF. (Initial value is ON)
* Not Received in Keyboard Part.
Soft (Controller number 67)
Status 2nd bytes
BnH 43H
n = MIDI channel number: 0H-FH (ch.1-ch.16)
vv = Control value: 00H-7FH (0-127) 0-63 = OFF, 64-127 = ON
* Not received when Rx.SOFT = OFF. (Initial value is ON)
* Not Received in Keyboard Part.
Portamento control (Controller number 84)
Status 2nd bytes
BnH 54H
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
BnH 5DH
n = MIDI channel number: 0H-FH (ch.1-ch.16)
vv = Control value: 00H-7FH (0-127), Initial Value = 00H (0)

NRPN MSB/LSB (Controller number 98, 99)
Status 2nd bytes
BnH 63H
BnH 62H
n = MIDI channel number: 0H-FH (ch.1-ch.16)
mm = upper byte of the parameter number specified by NRPN
ll = lower byte of the parameter number specified by NRPN
* 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.
* Not Received in Keyboard Part.
**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. 12). 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 the AT-S, NRPN can be used to modify the following parameters.
