M-Audio Oxygen 49 MK IV

Back in January 2016 the M-Audio Oxygen 49 was the highest rated 49 key controller under $200 with a Gearank score of 88. Since that time its ratings have fallen and it's no longer on our main list of recommended 49 key controllers - to see what we now recommend please read: our guide to The Best 49 Key MIDI Controller Keyboards.

The Oxygen 49 integrates with most major DAWs such as Ableton Live, Pro Tools, Logic, Cubase, and more, and it comes with transport controls.

Key features:

  • Keys: 49 full size synth-action with velocity sensitivity.
  • Pads: 8 which are velocity sensitive.
  • Arpeggiator: No, but the bundled software does.
  • Motorized Controls: No.
  • Bundled Software: Ableton Live Lite, Air Xpand!2 and SONiVOX Twist virtual synths.
  • Power: USB powered.
  • Connectivity: USB and TRS input for sustain pedal.
  • Control Hardware Directly: No.
  • Compatibility: Mac OS X 10.4.11 or later (10.5 or later recommended) + Windows 10, 8, 7, Vista, and XP.
  • Dimensions: 32.04" x 9.56" x 3.7"
  • Weight 6.4 lbs

The positive reviews center around it being excellent value at this price point, with most people finding it easy to set up and start working with right out of the box.

There were no consistent themes in the negative reviews other than a handful of people not liking the responsiveness of the pads - but very few had major issues with it.
