**NRPN**
The NRPN (Non Registered Parameter Number) message allows an extended range of
control changes to be used, letting you use control functions which are not defined in the
MIDI Specification.
NRPNs provide a great deal of freedom, and can be used with any manufacturer’s devices.
As a result, any particular parameter number can easily mean one thing when used for a
certain device, and mean something completely different on another device. Note that RPNs
and NRPNs require that a multiple number of messages be processed in the correct order.
However, a majority of the sequencers currently on the market cannot always be relied on
to consistently send messages in the proper order if the messages are located at almost
exactly the same point in time.
On the GS instruments, NRPN can be used to modify the following parameters. The range
of values for relative change parameters will be different with certain models.
Please see the explanation that follows the chart.

* 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.
