**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 this instrument, RPN can be used to modify the following parameters.

Data transmission
This instrument can use exclusive messages to exchange many varieties of internal settings with
other devices. The model ID of the exclusive messages used by this instrument is 00H 00H 3CH.
Data Request 1 (RQ1)
This message requests the other device to transmit data. The address and size indicate the type
and amount of data that is requested.
When a Data Request message is received, if the device is in a state in which it is able to transmit
data, and if the address and size are appropriate, the requested data is transmitted as a Data Set 1
(DT1) message. If the conditions are not met, nothing is transmitted.
