Features
Front Panel
1. LED Screen: The Oxygen 25 features a 3-digit LED display providing visual information regarding current
operation, programing and controller status.
2. Function Buttons: The Oxygen 25 features function buttons for programming, access to settings and advanced
features.
DirectLink Operation: In Auto mode, < and > will scroll
through the tracks. See your specific DAW's DirectLink
documentation which can be downloaded at m-audio.com/directlink.
Standard Operation: The < and > buttons do not send MIDI. In performance mode they will cycle the currently
selected LCD parameter (Global Channel, Program, or Preset). In Edit Mode, they will cycle through the currently
selected editable control.
3. Fader: Sends different types of standard MIDI CC messages or advanced MIDI messages based on the
assigned parameter or the active preset. The fader can be individually assigned to a different MIDI parameter.
For DirectLink operation, please see the DirectLink User Guide available at m-audio.com/directlink.
4. Knobs: Sends different types of standard MIDI CC messages or advanced MIDI messages based on the
assigned parameter or the active preset. Each knob can be individually assigned to a different MIDI parameter.
For DirectLink operation, please see the DirectLink User Guide available at m-audio.com/directlink.
5. Pads: Press these velocity-sensitive pads to send Note On/Off and velocity data when performing. To change
the pad octave assignment, hold down the Shift and the + or - octave button. These changes affect all eight pads
globally. To transpose from the default pad assignments, hold down the Shift and Select button and press the +
or - octave buttons. To reset the pads to the default factory assignments, hold down the Shift and both octave
buttons. The pads will only send on MIDI channel 10.
6. Transport Buttons: These buttons send standard MIDI CC, MIDI note, MMC (MIDI Machine Control) or other
advanced MIDI messages based on the parameter they are assigned to, or the active preset. Each Transport
Button can be individually assigned to a different MIDI parameter.
DirectLink Operation: These buttons map to the Transport Buttons in supported DAW applications to control
playback, record, start/stop, as well as enabling (or disabling) of the loop function.
Standard Operation: These buttons send standard MIDI CC, MIDI note, MMC (MIDI Machine Control) or other
advanced MIDI messages based on the parameter they are assigned to, or the active preset. Each button can be
reassigned to control various parameters in your DAW, including the transport controls, by using your recording
application’s MIDI Learn function.
7. Velocity-Sensitive Keyboard: The velocity-sensitive keyboard is not only the primary method of sending Note
On/Off and velocity data when performing, it is also used to access extended programing functions listed along
its upper edge.
8. Octave Buttons: The Octave buttons are used to shift the keyboard’s octave range up or down in one octave
increments, extending the octave range of the pads or keys.
9. Pitch Bend Wheel: This wheel creates expressive changes in performances by raising and lowering pitch.
Rolling the Pitch Bend wheel upward will raise an instrument’s pitch whereas rolling it downward will lower the
pitch. The upper and lower pitch bend limit is determined by settings on your hardware or software synthesizer,
not by the Pitch Bend wheel on the Oxygen 25 keyboard itself. Typically, this can be either a half note or an
octave up/down. This wheel is spring mounted and will return to the center detent position when released. The
Pitch Bend wheel is an assignable controller capable of sending a variety of MIDI messages other than pitch
bend data.
