* 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 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.

On the DP-900, RPN can be used to modify the following parameters.
