Assigning RPN/NRPN Messages to a Knob, Fader, Button, Wheel, or Pedal
Oxygen 25 allows transmission of all three necessary MIDI CC messages for RPNs and NRPNs by simply moving a
knob or fader or wheel 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.
• 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, wheel, or fader to control an RPN/NRPN on a connected hardware or software device requires
four values to be specified.
• Assigning a button or the sustain pedal to control an RPN/NRPN on a connected hardware or software device
requires three values to be specified.
The following example assigns a manufacturer specific NRPN coarse (134) message to a control on your Oxygen 25
keyboard:
1. Press the Edit button.
2. Press the Select button or Control Select (Ctrl Sel) key.
3. Select a knob, fader, wheel, button or the sustain pedal as described earlier in this guide.
4. Press the Control Assign (Ctrl Asgn) key.
5. Enter 134 (NRPN Coarse) using the number keys.
6. Press the Data 1 key.
7. Enter 6 using the number keys (or the MIDI CC).
8. Press the Data 2 key.
9. Enter the value to be transmitted via MIDI CC 98 (LSB) using the number keys.
10. Press the Data 3 key.
11. Enter the value to be transmitted via MIDI CC 99 (MSB) using the number keys.
12. Press the Enter key.
Non-Volatile Memory
The Oxygen 25 keyboard features non-volatile memory, which allows for automatic saving of presets when the device
is powered off. The current controller and channel assignments are stored even if the Store function has not been
used. The Program, Bank LSB and Bank MSB data, Global Channel setting, and last used memory preset are also
stored.
Restoring the Factory Settings
Factory default settings can be restored by holding down the - and + buttons during power-up. At this point all
previously saved data will be erased.
