Status 2nd byte 3rd byte
BnH 63H mmH
BnH 62H llH
n = MIDI channel number:0H – FH (Ch.1 – 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. On the SC-8850, 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 (Controller number 6) 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 244). On the SC-8850, 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 SC-8850, 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.
* It is not possible to simultaneously use both Chorus Send Level and Delay Send Level on
a single Drum Instrument.
* Data entry LSB (llH) is ignored.

Status 2nd byte 3rd byte
BnH 65H mmH
BnH 64H llH
n = MIDI channel number: 0H – FH (Ch.1 – 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.
* 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 110, 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 244).
On the SC-8850, RPN can be used to modify the following parameters.

Set condition where RPN and NRPN are unspecified. The
data entry messages after set RPN null will be ignored. (No
Data entry messages are required after RPN null).
Settings already made will not change.

●Program Change
Status 2nd byte
CnH ppH
n = MIDI channel number: 0H – FH (Ch.1 – 16)
pp = Program number: 00H – 7FH (prog.1 – prog.128)
* Not received when Rx.PROGRAM CHANGE = OFF. (Initial value is ON)
* After a Program Change message is received, the sound will change beginning with the
next Note-on. Voices already sounding when the Program Change message was
received will not be affected.
* For Drum Parts, Program Change message will not be received on upper byte of the
bank numbers (the value of Control Number 0 is other than 0 (00H)).
●Channel Pressure
Status 2nd byte
DnH vvH
n = MIDI channel number: 0H – FH (Ch.1 – 16)
vv = Channel Pressure: 00H – 7FH (0 – 127)
* Not received when Rx.CH PRESSURE (CAf) = OFF. (Initial value is ON)
* The resulting effect is determined by System Exclusive messages. With the initial
settings there will be no effect.
