*A Note-on received immediately after a Portamento Control message will change
continuously in pitch, starting from the pitch of the Source Note Number.
* If a voice is already sounding for a note number identical to the Source Note Number,
this voice will continue sounding (i.e., legato) and will, when the next Note-on is
received, smoothly change to the pitch of that Note-on.
* The rate of the pitch change caused by Portamento Control is determined by the
Portamento Time value.

mm = upper byte (MSB) of parameter number specified by RPN

<<< RPN >>>
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.
