M-Audio Oxygen line of portable MIDI controller keyboards
February 13, 2006
For the travelling synth musician/composer, the M-Audio range of Oxygen keyboards provide a versatile range of MIDI control options, good looks and portability, in value for money packages.
They’ve just redesigned the baby of the range - the 25-key Oxygen 8 version 2, which features a 2-octave full-size velocity (not aftertouch) sensitive synth-action keyboard, 8 fully-MIDI assignable controller knobs, 6 transport buttons, LCD display, 5 dedicated function buttons, and two fully assignable data wheels set top-left of the machine. It can be powered directly from an active USB port, and weighs in at only 4 pounds.
Full specification is available here.
The 4-octave Oxygen 49 builds on the compact 8, providing 8 input knobs, 9 sliders, 15 assignable buttons, 2 data wheels, and a sustain pedal input. The data wheels have been moved to the left-hand side of the keyboard.
Full specification is available here.
The top-of-range 5-octave Oxygen 61 is virtually identical to the Oxygen 49, simply sporting an additional octave.
Full specification is available here.
All three keyboards come with a free copy of Ableton Live Lite 4 and will connect to PC and Mac without problems.
None feature direct keyboard aftertouch response, but for this price you wouldn’t expect them to. The compactness of the Oxygen 8 will be useful as a trigger keyboard and a very compact sequencer-buddy. Musicians needing more creative control of their synths and software will probably appreciate the additional controls, particularly the sliders and the sustain pedal input, on the upper models.

It features 88 graded weight hammer-action keys, and three velocity curves plus fixed velocity for synth work.
It boasts a large 64MB sound bank in which its 14 sounds are stored. The 3-layer stereo grand piano samples alone take almost half of this space.
The acoustic sample is taken from the classic Yamaha C7 concert grand.
Its 14 patches are:
- Stereo Grand Piano (Yamaha C7)
- Bright Grand Piano
- Fender Rhodes
- Wurlitzer E.P.
- Bright Yamaha DX7 FM Classic E.P
- Warm Yamaha DX7 FM Classic E.P
- Hohner Clavinet D6
- Vibes (with hybrid mallets)
- Hammond B3 Percussion Organ
- Hammond B3 Rock Organ
- Acoustic Upright Bass
- Fingered Electric Bass (including harmonics)
- String Ensemble
- Warm, Lush Synth Pad
It has a massive 126 note polyphony, essential for sustained piano playing, sustain, sostenuto and expression pedal inputs, pitch and modulation wheels, 3 reverbs, chorus and tremolo, 2-stage equalizer, 12-key data entry pad with 3-digit LED screen, dedicated volume faders for master, layer and split parts, built-in USB and MIDI interfaces.
The ProKyes 88 appears to be a well-constructed, class instrument which has focussed on being a good all-round keyboard and basic MIDI controller for the travelling / gigging musician. Great care has been taken on achieving high-quality samples and playing experience, housed in a sleek, uncomplicated case weighing in at 48 pounds (21 kgs).
It’s definitely one of the most affordable professional digital pianos around, and could prove popular.
