Assigning RPN/NRPN messages to a Knob, Slider, Button, or Pedal
Oxygen Series keyboards allow transmission of all three necessary MIDI CC messages for RPNs and NRPNs by
simply moving a knob or slider or by pressing a button or the sustain pedal.
The "Control Assign" setting allows assignment for control of the RPN Coarse (132) and RPN Fine (133), as well
as NRPN Coarse (134) and NRPN Fine (135) parameters (see Section 10 - MIDI Messages Defined and
Appendices A & B for more information).
The Data 1 setting lets you specify which MIDI CC number is sent to alter values (usually: Coarse=CC 6; Fine=CC
38). The Data 2 setting defines what value is sent for LSB (RPN: CC 100, NRPN: CC 98) while the Data 3 setting
defines which value is sent for MSB (RPN: CC 101, NRPN: CC 99). Together, the LSB and MSB values specify the
RPN/NRPN parameter to be edited.
Assigning a knob to control an RPN/NRPN on a connected hardware or software device requires four values to be
specified.
The following example assigns a manufacturer specific NRPN coarse (134) message to a control on your Oxygen
keyboard:
1. Select a Knob or Slider as described earlier in this guide
2. Press the Advanced button
3. Press the Control Assign key
4. Enter 134 (NRPN Coarse) using the number keys (see Appendices B and F)
5. Press the Enter key
6. Press the Advanced button
7. Press the Data 1 key
8. Enter 6 using the number keys (or the MIDI CC number for value changes as required by your device)
9. Press the Advanced button
10. Press the Data 2 key
11. Enter the value to be transmitted via MIDI CC 98 (LSB) using the number keys
12. Press the Enter key
13. Press the Advanced button
14. Press the Data 3 key
15. Enter the value to be transmitted via MIDI CC 99 (MSB) using the number keys
16. Press the Enter key
See Section 10 - MIDI Messaged Defined for an in-depth explanation of RPN/NRPN MIDI messages and their usage.
