M-Audio Oxygen MK5 25｜25-Key USB MIDI Keyboard Controller with Smart Chord, Smart Scale, and Auto-Mapping Control
A USB MIDI keyboard controller that balances composition, pad input, and DAW workflow efficiency
The M-Audio Oxygen MK5 25 is a USB MIDI keyboard controller from M-Audio. It features a 25-key full-size velocity-sensitive keybed, along with Smart Chord, Smart Scale, a built-in arpeggiator, two banks of 8 velocity-sensitive pads, and 8 assignable knobs, enabling users to complete arranging, rhythm input, and DAW control more quickly. For creators who need to balance performance, production, and mixing in a limited desktop space, this is a highly integrated MIDI keyboard solution.
Compared with entry-level controllers that only offer keyboard input, the M-Audio Oxygen MK5 25 delivers a more complete DAW controller workflow through auto-mapped DAW control, Note Repeat, smart performance assistance, and real-time parameter feedback on the display. Compared with other compact controllers in its class, its strength lies in combining playing, beat-making, plug-in control, and basic mixing operations into a single device.
Suitable For：Desktop music production, beat making, MIDI composition input, home recording studios, live performance control
Who should buy the M-Audio Oxygen MK5 25?
Who Should Buy
Creators just starting with computer-based composition who want one controller for playing, drumming, and basic DAW operation
Home-recording musicians with limited desktop space who want a 25-key size while still keeping knobs, pads, and fader control
Beatmakers or electronic music producers who value Note Repeat, the arpeggiator, and a workflow for quickly controlling virtual instrument parameters
Arrangers who already use DAW software and want to reduce mouse use while improving recording, mixing, and arranging efficiency
Who Should NOT Buy
Users focused on full two-hand piano performance who need a range of 49 keys or more; 25 keys may not be enough
Advanced studio users who already have a complete large MIDI control system and do not need an additional small desktop controller
Users who only want to learn piano and do not plan to work with DAWs, virtual instruments, or MIDI composition workflows
M-Audio Oxygen MK5 25 Core Technologies and Features
25-key full-size velocity-sensitive keybed: Delivers a playing feel closer to a full keyboard, balancing melody input, harmony arranging, and basic performance control, ideal for desktop production environments.
Smart Chord function: Trigger full chords with a single key, supporting Major, Minor, and voicing settings. It also includes Custom Mode, allowing users to define chord structures and apply them to all keys.
Smart Scale function: Restricts the keybed to a selected scale, preventing out-of-scale notes, and supports more than 15 scale variations, making it especially useful for beginner composition and improvisation.
Built-in arpeggiator: Offers Type, Octave, Gate, and Swing controls, and can run in sync with the internal keyboard clock or the DAW clock to quickly create groove and motion.
2 banks of 8 velocity-sensitive pads: A total of 16 switchable trigger assignments, suitable for drum input, sample triggering, clip control, and rhythm programming, with Note Repeat to speed up beat production.
Note Repeat rhythm repeat: Automatically repeats the selected note division on the pads, supporting Momentary and Latch modes, making it easy to create common Trap, Hip Hop, and electronic rhythm patterns.
8 assignable knobs: Can be mapped to virtual instrument and effects parameters such as filters, resonance, envelopes, effect depth, and send levels, improving real-time sound shaping efficiency.
1 assignable fader: Can be used for volume, expression, mixing, or custom MIDI CC control, retaining practical linear control on a compact controller.
Auto-mapped DAW control: Built-in presets and DAW button layouts can automatically map to transport, fader, pan, record arm, solo, mute, select, and other controls in most mainstream DAWs.
Mainstream DAW compatibility: Supports major music production platforms such as Ableton, Pro Tools, MPC Beats, Cubase, Logic, and Studio One, reducing setup barriers.
Virtual instrument preset integration: Provides preset control mappings for the included Mini Grand and Hybrid 3, allowing direct access to commonly used parameters during creation.
Transport control buttons: Directly control DAW play, stop, record, and other functions, reducing time spent switching between keyboard and mouse.
Display for real-time feedback: Quickly check current parameters and operating status for more intuitive live adjustments.
Ergonomic Pitch / Mod wheel design: Suitable for pitch bends, vibrato, and expressive performance, especially important for synth leads, bass, and tonal expression.
Sustain pedal input: Provides 1/4" sustain pedal connectivity, helpful for piano performance and more natural expression control.
Smart Chord performance assistance
Press one key to trigger a full chord, greatly speeding up harmony sketching, arrangement trials, and idea capture.
Supports Major, Minor, and different voicing settings, allowing fuller harmonic layers with one hand.
Custom Mode lets users manually enter chord structures such as 1-b3-5-b7, after which each key can be automatically applied based on the root note.
Especially suitable for EDM, Lo-fi, Hip Hop, pop arranging, and creators without a formal keyboard background.
Smart Scale composition safeguard
When enabled, it only outputs notes within the selected scale, effectively avoiding wrong notes and improving the success rate of improvisation recording.
Supports more than 15 scale variations, suitable for different creative directions from pop and jazz to electronic music.
Parameters can be adjusted directly on the keyboard without frequently returning to the software screen, keeping the creative flow uninterrupted.
Especially useful for beginners and producers who need to quickly produce demos.
Built-in arpeggiator and rhythm generation control
The built-in arpeggiator automatically cycles through pressed chords or notes in sequence, quickly creating groove and melodic motion.
Provides Type, Octave, Gate, and Swing controls for fine-tuning rhythm density, length, and feel.
Can sync to the internal keyboard clock or the DAW clock for easy integration into arrangement projects.
Supports Latch and Momentary modes, suitable for different workflows in live performance and composition.
16-pad triggering and Note Repeat beat-making workflow
The two banks of 8 velocity-sensitive pads can be switched as needed, balancing drum performance, sample triggering, and clip control.
The pads are velocity-sensitive, allowing more natural drum dynamics and more humanized rhythm programming.
Note Repeat can continuously repeat the selected note division, quickly creating hi-hat rolls, trap fills, and electronic rhythm variations.
Offers both Momentary and Latch modes, suitable for both live performance and loop-trigger workflows.
8 assignable knobs and 1 assignable fader control architecture
The 8 knobs can be custom-mapped to plug-in and virtual instrument parameters, ideal for filter, effect depth, and synth tone adjustments.
The 1 fader can be used for volume, expression, or any MIDI CC control, making it practical for mixing and automation recording.
Allows users to perform more tactile real-time sound control without relying entirely on the mouse.
Especially suitable for electronic music, scoring, and live performance workflows that involve adjusting parameters while recording.
DAW auto-mapping and transport control workflow
The controller can automatically map to common functions in most mainstream DAWs, reducing tedious MIDI Learn and manual setup time.
It can control common mixing and recording functions such as Transport, Pan, Record Arm, Solo, Mute, and Select.
Simply select the corresponding DAW on the keyboard and complete the basic preference settings to get started quickly.
For users who need efficient movement from inspiration to recording to rough mixing, it significantly reduces workflow interruptions.
Display and performance control details
The built-in display provides real-time parameter feedback, making it easy to confirm the current mode and control values.
The Pitch and Modulation wheels use an ergonomic layout to improve operational stability during live performance.
