This is a really well built, nice-feeling midi controller, but it integrates poorly (at least on my Windows set up). When it works, it really puts you in command of the NI instruments you own and is an upgrade to the experience of working with them.
However, too often it just doesn't work. Most times it is not recognized by the Komplete software, or at least not fully (knobs function but keyboard doesn't). I read posts saying to activate it in Midi settings in the Komplete standalone to fix this problem, but I have to do that every time and even then sometimes it just will not activate.
So overall, I cannot recommend it. The time I've lost trying to get it to work is measured in hours, not minutes, and when I have pressing deadlines this is an inspiration killer and stress inducer.
