I'm a classical pianist and got this keyboard mainly as a midi controller for orchestral vsti with an option to sketch piano parts without needing to use my main piano controller. And I'm very happy with the purchase.
It's a quality construction and the action is more than adequate for any use. I'm using it now exclusively and haven't felt the need to switch to my stage piano to improve piano part performances.
The control options offered are fantastic, allowing up to 4 channels to be controlled at a time, fully programmable, layered, split or any combination, with different key response and joystick/pedal assignments per channel. You can connect up to 2 switches and another 2 expression pedals, full midi in/out interface with an option to merge the input and send it either to the midi out or usb, all very useful features.
The action itself is a bit sluggish but not in a way that would prohibit fast playing as some reviews claim. I've yet to find something that I can't play on this instrument and I've tried some of the most demanding classical pieces on it. Noise wise, I find it relatively quiet. There is some noise of course, but it's soft and low pitched and not as unpleasant as in most mid-low tier digital piano actions.
A big part of how the action feels comes down to audio feedback and the default tuning is pretty slow for most vsti. Switching to the soft preset or making your own through the accompanying editor reveals a very enjoyable instrument. This is the exact same action used in Keylab 88 and KK S88 after all.
Finally the joysticks. It's like having 3 mod wheels and 3 pitch bends, all programmable. I like that a lot. The springy ones for pitch bend type control are perfectly fine. The free ones for mod control will require some brain adjustment but they're serviceable. Once you adapt to the small movements and minimal force required, they get the job done. It's down to you if you'll end up liking them more than a traditional wheel though; I suspect most people won't.
All in all for the money this is a fantastic piece of kit. 88 hammer action keys with aftertouch, 3 dual axis programmable joysticks, 4 pedal inputs, midi i/o, 4 simultaneously active fully programmable zones per preset, virtually infinite presets and editor software that allows customizing every aspect of the action. So much to like in this instrument. Highly recommended.
