Capable and Flexible, if a bit chunky

The Oxygen25 is a welcome addition to your studio! For the price, it delivers exactly what you need without many frills— 25 keys, octave control, pitch bend and modulation wheels, a volume slider, transport controls, and eight MIDI CC knobs. It's a fairly large controller for only having 25 keys (partially due to the fact that it has full-length keys instead of the common "mini keys"), so it's not the best solution for producers who also need a performance tool (even though Ean Golden famously used this controller with Traktor to DJ full sets), but it's right at home in a studio for sure.

Great portable unit

Portable! Used one of these for many years with a laptop when doing a idea on a laptop. It would also work well for people with small setups, on a very tight budget, or just starting out. Doesn't feel cheap, and held up well. Sold it after no longer needing it.

Classic piece from all studio.

Good USB Keyboard / Controller, Easy Setup in most DAW's

I've been using this about every day since it was new (MK3) and it's been a while. Still, it hasn't degraded in usefulness or in wear and tear. Nowadays I'd go for something slimmer, maybe with some drum-pads integrated, but as a overall cheap, down to business, no-nonsense keyboard / controller I think it still shines more than many alternatives out there. Works flawlessly with both Ableton Live 9 and Reason 8! Had some trouble getting the "DirectLink" setup function with Cubase, but it's easy to use the midi-learn feature, so no real problems. I recommend it!

Very good MIDI controls

I don't use this for the keyboard as I have another 88 key keyboard in use, but for the modwheel, pitchbend and midi CC controls this is a very good low cost item.

properly replacing this soon but good little beast

I've had this since I friend gave it to me and I've used it in FL and in Ableton and it worked absolutely well until Ableton 10 where suddenly it doesn't wanna work anymore... oddly enough just in time for the Komplete Kontrol M34 and well.... I'm gonna trade this in for like 10 bucks and get some coffee after placing my order for that.

Great MIDI keyboard for mobile studio

I have it for the time I spend out of studio, because instrumental ideas should be fixed as soon as they arive. I use it together with Lenovo Ideapad which is good to run Cubase Pro 10 with all libraries on external SSD.

Compact and reliable MIDI keyboard for studio use

Just needed a compact, solid (and preferably good-looking) midi keyboard to have on my desktop in the studio. This thing is great, has worked flawlessly, good action, great price.

Mediocre

Mediocre at best. The keys on this thing feel like there's a layer of playdough underneath the keys so i guess you could say it has a squishy action. I'm unsure if this thing as aftertouch but I'm betting on no. either way, save your money and buy a better controller if you can afford it.

Darker than the picture.

Plenty of macro's for automated tracking while recording with it. Not the greatest feel but for a 25-key controller it's good.
