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.

* When an Active Sensing message is received, the unit will begin monitoring the interval
at which MIDI messages are received. During monitoring, if more than 420 ms passes
without a message being received, the same processing will be done as when All Sound
Off, All Note Off, and Reset All Controllers messages are received. Then monitoring will
be halted.
