Control Changes include RPN (Registered Parameter Numbers), which are extended.
When using RPNs, first RPN (Controller numbers 100 and 101; they can be sent in any order) should be sent in order to select the
parameter, then Data Entry (Controller numbers 6 and 38) should be sent to set the value. Once RPN messages are received, Data Entry
messages that is received at the same MIDI channel after that are recognized as changing toward the value of the RPN messages. In order
not to make any mistakes, transmitting RPN Null is recommended after setting parameters you need.
This device receives the following RPNs.
RPN Data entry
