Oxygen 88 | User Guide 33 |
Assigning RPN/NRPN messages to a Knob, Slider, Button, or Pedal
Oxygen 88 allows transmission of all three necessary MIDI CC messages for RPNs and NRPN's by simply moving a knob or slider or by pressing a button or 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 "10: MIDI Messages Defined" on page 34 for more information).
The Data 1 setting lets you specify which MIDI CC number is sent to alter values (usually: Coarse = CC 6; Fine =
CC38). 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.
