MIDI CC, Note On/Off, and Program/Bank Change messages are sent on a specific MIDI Channel.  The controls on most Oxygen Presets default to follow the Global Channel, which is Channel 1 by default.   The Channel Assign function (CHAN ASGN) assigns a Knob, Slider, Button or the Sustain Pedal jack to a specific MIDI channel.

1. Move or press to select a control.
2. Press the Advanced button
3. Press the Channel Assign key - the LED display will show the currently assigned MIDI channel for the active control (for example "c.0.2.")
4. Enter the new MIDI channel number using the number keys
5. Press the Enter key

When assigned to channel "0", the control (Knob, Slider, Button or Sustain Pedal jack) will transmit on the Global MIDI Channel.   After programming your device, please refer to this article to store your changes to memory.
