M-Audio Oxygen 25 USB MIDI controller (3rd Gen) Reviews


M-Audio Oxygen 25

I\'ve only been playing with this thing for a few hours, but already I\'m in love with it; basic setup couldn\'t have been easier, it feels solidly built without being heavy, the key action is light but not wishy-washy (although I\'m not really a keyboard player, so your mileage may vary on this), and the DAW autoconfig is pretty nifty. The more advanced features (assigning MIDI control codes to buttons, etc.) are a little opaque but the ability to store a selection of presets means that it\'s unlikely you\'ll need to do it often, and for its diminutive size it packs a lot of features.

The only complaint I might have is that I\'d have preferred to have the control knobs on the left of the keyboard (playing with my right hand and adjusting the knobs with the left is made slightly awkward by needing to cross my arms), but other than that this is pretty much the perfect portable MIDI controller -- small, light, and feature-laden.

This piece of kit I have used with Windows (xp and the recent upgrade to 7) and OS X. On all operating systems it is very easy to use and get started with.

The weight to it makes gives it a very nice feel and but it\'s not too heavy to have on your lap if you\'re on the move. The velocity sensitive keys are brilliant and respond amazingly. I have to many midi keyboards that delay on release or don\'t give the control this one does.

All the controls are easy to program and give a depth of control that is normally only found on the most expensive of models.

This is a fantastic piece of kit and I would recommend it to anyone. top marks
