Great build quality, great keyboard feel, pitch and mod also. Good daw transport control but it's a shame you only get the great features like arp and scale only if u have an instance of Komplete Kontrol open on your track, same for the plugins you use. Nks is great but it would have been the best midi controller if you could open a NKS plugin standalone on a track and get the visual controls on the display without Komplete Kontrol. That would probably incourage a lot more plugin developers to adopt the NKS compatibility. It's nice to have a hands on control over knobs for your digital synths. Maybe in the future. Overall, I don't regret the big bucks for it.
