3.8.3 Assigning RPN/NRPN Messages to a Fader or Encoder

Many of today’s synthesizers and music applications can receive and process RPN and NRPN MIDI messages to allow control of an array of useful settings and features. However, RPN/NRPN messages are different from most other MIDI data as they consist of two or more MIDI messages that have to be sent in sequence.Traditionally, you would have to send multiple MIDI messages manually and one by one in order to change a single RPN/NRPN setting on your synthesizer or music software.This can turn into a difficult and lengthy procedure with many MIDI controllers.

The Axiom simplifies this procedure by combining commonly used RPN/NRPN messages and making them accessible just as if they were an extended set of standard MIDI controllers. In addition to the common MIDI controllers 0 -127, the Axiom lets you access RPN/NRPN features through additional controller numbers 128 through 156.The amount of additional MIDI controller numbers depends on the controller type (rotary encoder, fader, pad, etc.). Lists of supported RPN/NRPN messages and the associated extended MIDI controller numbers (sorted by controller type) can be found in Appendices D, E, F and G.

Once assigned to one of your Axiom’s controls, complete multi-part RPN/NRPN messages will be transmitted simply by moving a fader or using an encoder or one of the Axiom’s other controls.

Assigning your Axiom’s faders or encoders to send RPN or NRPN messages is done in the same fashion as assigning a regular MIDI controller.

To assign RPN or NRPN numbers:

49- and 61-note versions:

<Select the control to edit.

<Press the Ctrl Assign button.

<Enter the desired RPN or NRPN number using the numeric keypad.

<The Data 2 button can be used to define the RPN LSB value, while the RPN MSB can be defined using the Data 3 button. This process is detailed in section 3.8.1.

25-note version:

<Select the control to edit.

<Press the Advanced button.

<Press the Ctrl Assign key.

<Enter the desired RPN or NRPN number using the numeric keypad.

<Press the Enter key to confirm.

<Press the Advanced button.

<The Data 2 key can be used to define the RPN LSB value, while the RPN MSB can be defined using the Data 3 key. This process is detailed in section 3.8.1.

You will find that most data sheets for those devices that make use of NRPNs give the MSB and LSB values that you should enter with Data 3 and Data 2 (see Appendix B3 for Roland/XG defined NRPN messages). Some manuals however may only give you the hex values. The Axiom requires you to enter the decimal value. You can convert hexadecimal values to decimal using the table in Appendix H.

For a detailed description of RPN/NRPN data see section 5.2.
