Made the decision to upgrade from my teeny-tiny controller to a 49 with normal-sized keys for my sausage fingers, and after having looked at some of the other options available, I'm glad I spent those extra pennies on this.
For starters, the actual aesthetics of the keyboard are nice, a lovely matte-finished grey that'll fit right in with any contemporary setup. The LEDs or display aren't too obnoxious either. Everything feels sturdy and well built, can't see anything breaking soon, even with expressive or extensive playing. The keys are "synth action" which despite not being weighted; feel great to play on. The addition of velocity sensitive drum pads is also a nice touch, and are pretty fun to use and easy to program.
The I/O is fairly straight-forward, albeit limited with only a USB port and a 1/4 sustain pedal input. For folks like me it's enough, but having more ports for expression pedals or MIDI output would be nice. Not a deal-breaker though.
The area where this keyboard really shines however, is it's DAW integration and compatibility. Following the easy setup and registration guide, I was able to install the appropriate drivers and manuals for Cubase, and was up and running within a matter of minutes. Being able to use it as a generic controller is all fine and well, but having the option to optimize it for maximum control within your DAW is a very nice touch.
Overall, I'd definitely recommend this controller to any aspiring producers or hobbyists looking to get more mileage out of their VSTs. Despite the lack of weighted keys or I/O ports, there's positively nothing I can fault about this controller. Good job Nektar.
Ten-outta-ten.
