Setup
Connecting Your Keyboard
1. Plug the USB cable provided with your Oxygen 25 to a free USB port on your computer.
2. Plug the other end of the USB cable into the USB input on the Oxygen 25.
The single USB cable not only powers the keyboard but also sends MIDI data to and from your computer system. If
you intend to use your Oxygen 25 with a USB hub, make sure the USB hub uses an external power supply. Using a
passive USB hub which does not use a power supply may not provide enough power if other devices are connected
to the hub. We do not recommend connecting an audio interface to the same USB hub as the Oxygen 25.
You can also use Oxygen 25 with your iPad Camera Connection Kit to control supported music creation apps.
The iPad Camera Connection Kit is available from the Apple Store.

DirectLink Installations
Rather than assigning parameters one by one, DirectLink automatically maps Oxygen 25’s controls to many of the
most frequently used digital audio workstation (DAW) features and settings. When used with a supported DAW, you
can control the transport, mixing controls (faders and panning) and virtual instrument or signal processing plug-in
parameters. You can also switch between DirectLink and custom MIDI operation on the fly to match your particular
needs.
To enable DirectLink with your Oxygen 25, you may need to install some additional software, including the DirectLink
"personality" for your specific DAW. Visit m-audio.com/directlink for a current list of DAWs that support DirectLink
and to download any necessary profiles.
Getting Started
Connect the Oxygen 25 to your computer and then open your software. In your software’s Preferences, Options, or
Device Set-Up menu, select Oxygen 25.
For further information about configuring your software to receive MIDI data from your Oxygen 25, and using software
instruments with the application, refer to the documentation provided with that product.

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
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.

10. Modulation Wheel: This wheel is used to add expression to performances by changing the intensity of certain
effects. By default, most synthesizers assign this wheel to control vibrato (change in intonation) or tremolo
(change in volume) although it is usually possible to reassign the function of this wheel through the instrument’s
control panel. Rolling the Modulation Wheel upward will increase the modulation effect, while rolling downward
will reduce the effect. The Modulation Wheel is an assignable controller capable of sending a variety of MIDI
messages other than Modulation data.
11. Control Button (C10): This mapable button can be assigned to send Note, CC, and other MIDI messages.
For DirectLink operation, please see the DirectLink User Guide available at m-audio.com/directlink.
Rear Panel
1. USB Port: The USB 2.0 port (backward-compatible with USB 1.1) delivers
power to the keyboard and transmits MIDI data when connected to a
computer.
2. Sustain Pedal Input: This input accepts a momentary-contact foot pedal
(not included). When pressed, this pedal will sustain the sound you are
playing without having to keep your fingers pressing down on the keys. The sustain pedal input can be assigned
to send Note, CC, and other MIDI messages.
NOTE: The polarity of the sustain pedal is determined by the keyboard upon startup. When an Oxygen 25
keyboard is powering up, the sustain pedal is assumed to be in the "up" (Off) position. It is important that the
sustain pedal is not pressed during startup, otherwise the pedal will reverse its operation, and notes will sustain
when the pedal is not pressed.
3. On/Off Switch: Use this switch to power the device on or off. When this switch is set to the “on” position,
Oxygen 25 is powered through the USB connection to your computer.
4. Kensington Lock Connector: This connector is compatible with standard laptop-style Kensington security
cables for theft protection.
