I am using it in Logic Pro X and to use all the buttons on the keyboard I had to "hack" the files and move some stuff around. Shouldn't be needed for a Midi keyboard that is still being sold and loved. I like the way it feels though, very sturdy and a great keyboard.
This keyboard is just that a keyboard it has eight faders, knobs and pads, on my model the pads werent great and to be honest i wasnt a big fan of the knobs as they are endless encoders, which is not my thing. however the semi weighted keyboard feels great which i would argue is the most important part.
I own 2 of these and both start crapping out after 3 years. I guess when it comes to midi controllers, M-Audio need's to find a way to improve their products to last.
I'd say it's pretty good. There are a few reasons I would choose something else if this one broke: It's really heavy. The pitch bend wheel feels really cheap and unresponsive. The keys are also a bit weird.
