**RPN**

Control Changes include RPN (Registered Parameter Numbers), which are extended para-

meters whose function is defined in the MIDI specification.

RPN can be used to change instrument parameters.

When using RPNs, first the RPN (Controller numbers 100 and 101; they can be sent in any

order) is transmitted to specify the parameter you wish to control. Then, Data Entry messa-

ges (Controller numbers 6 and 38) are used to set the value of the specified parameter.

Once a RPN parameter has been specified, all further Data Entry messages on that channel

are considered to apply to that specified parameter. In order to prevent accidents, when the

desired setting has been made for the parameter, it is recommended that RPN be set to

Null.

**NRPN**

Control change has an extension field called NRPN (non registered parameter number) in

which device-specific function can be defined.

The NRPN can be set without restriction on manufacturer or model. This means that the

same parameter number can be assigned different functions by some manufacturers.

Therefore, the device which receives this message may not operate as expected.

With NRPN or RPN, messages should be processed in the correct order. However, conven-

tional sequencer cannot assure the correct order of MIDI messages occurring at almost the

same time.

When using NRPNs, first the NRPN (Controller numbers 98 and 99; they can be sent in any

order) is transmitted to specify the parameter you wish to control. Then, Data Entry messa-

ges (Controller numbers 6 and 38) are used to set the value of the specified parameter.

Once a NRPN parameter has been specified, all further Data Entry messages on that chan-

nel are considered to apply to that specified parameter. In order to prevent accidents, when

the desired setting has been made for the parameter, it is recommended that RPN be set to

Null (RPN number=7FH/7FH).
