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> (p. 13). 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 HP-337, 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.
*
Data entry LSB (llH) is ignored.

**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 MSB and RPN 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 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 4. "Examples of actual MIDI
messages" <Example 4> (p. 13).
On the HP-337, RPN can be used to modify the following parameters.

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 messages will not be received on bank numbers 129-
16384 (the value of Control Number 0 is other than 0 (00H)).

The resulting effect is determined by System Exclusive messages. With the initial
