If I were buying for looks, I'd have got something else. I'm not a fan of the redand grey ribbed end cheek things. But, in terms of playing, it's lovely. All the controls feel solid but smooth and responsive. I gather ther internal processing of controllers is at a higher resolution than MIDI, and they do feel smoother than most controls on master keyboards in this range. The pads are good and the pressure is very controllable; the faders are easy to use for fine parameter control, and the weighting of the keyboard is, for me, nicely balanced between having enough weight to make it possible to control the velocity properly and being light enough to play fast parts without too much physical effort.
I bought it specifically because of the two pedal inputs and the 5-pin DIN MIDI input, which a lot of master keyboards in this range don't seem to have. It means I can use my old stage piano as a second keyboard without having to plug in a separate MIDI-USB box.
Assigning controls is very easy, and the workflow in general seems pretty straightforward. The features do seem a bit limited, and the LCD display is a bit cheap-looking, but if, like me, all you need to do is assign all the controls to whatever note, controller and channel you want and get on with playing it, it's great.
I haven't used the DAW controls yet, because I'm happy using my laptop for that stuff, but, as a performance keyboard, I'm very happy with it.
