The thought of spending $500 on up for a top of the line controller is not very appealing. I'd just buy a real synth with onboard sounds that can double as a controller if I were going to spend that sort of money. MIDI controllers should work well and be inexpensive in my opinion. The technology involved in making a strong controller is FAR from rocket science and should NEVER be the cost of a space shuttle. Anyway this controller fits the bill pretty well... no problems with the one I own or it's price point.


Microsoft XP Pro doesn't recognize the drivers as "offical" Microsoft approved drivers. But I installed them anyway trusting M-Audio gear to work properly in this environment without conflict (I also have a M-Audio Soundcard which is great). The drivers installed and work fine. Granted this should not be an issue or even discussed here.... shame on M-Audio for allowing this to be an issue at all.

Quality is quite good at this price range. Yes it's got a plastic case and may not be for serious live work. but at home on the home studio desk it is just fine. The knobs, keys, sliders, etc. all work perfectly and feel quite excellent... on my unit anyway... I am here at this site because I am considering buying an additional Radium 49 for another computer. So yes I'm satisfied with the quality of the one I own.

My experience read more is that this is a great value at this price.
