The NRPN (Non Registerd Parameter Number) message allows an extended

be used to modify sound parameters etc.
To use these messages, you must rst use NRPN messages (Controller
number 98 and 99, their order does not matter) to specify the
parameter to be controlled, and then use Data Entry messages to
specify the value of the specied parameter. Once an NRPN parameters

will modify the value of that parameter. To prevent accidents, it is
recomended that you set RPN Null (RPN Number = 7FH/7FH) when you have
nished setting the value of the desired parameter.

<<< RPN >>>
Control Changes include RPN (Registered Parameter Numbers), which are
extended.
When using RPNs, rst 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.
