The layout of the keyboard is well thought out. There are enough buttons to preform certain functions (sometimes you get units with lots of dual use buttons and things can become a pain when you have to a lot of adjustments). If you are still unsure there are plenty of videos on youtube to help you out! It is very similar to other competing MIDI keyboards so if you are familiar with those you won't have a problem.

And unfortunately it's currently unavailable on the m-audio website. When you adjust on screen it will change the value, however once you touch the physical knob again it will snap to wherever the knob is pointed. This is a pain when you can't remember what exact setting you had had on before. This means that when you try to adjust one of your on screen settings using the knob, it will automatically snap to where the physical knob is. Lets also note that the MIDI knobs are not infinity (you they have a limit to how far they can be turned either way. I found that I really didn't use synths in a way that required me to have the midi control so it was no problem to not have. And I may have gotten frustrated and learned to live without the knob control feature. Now I'll be honest, I didn't know much about MIDI keyboard/controllers when I first tried to get it to work. Getting it to work with your DAW is another issue. On my mac I didn't have to install any drivers and I was able to use keys, pitch bend and the octave problem with no problems. The set up for general use was very simple. Octave up/down or transpose up/down button Bring it to your favourite jam space just incase, it will fit easily on almost any desktop, use it to control your DAW or even hook it up to a synth and play on. The Oxygen 8 V2 is perfect for somebody that wants to make MIDI music on the go. I know it's plastic, but this thing is durable.

I actually got this as part of a college program and used it everyday.
