I had pa50sd, and the feel of keys was great. I mean when I moved my fingers over the keys and played, the keys physically felt so comfortable,pleasant, and soft to touch and play . I swabbed my Pa 50 sd with Pa 600. It is a very nice keyboard software wise and ease of moving the files , but the keys show some resistance physically. They are not as smooth and fluent as the pa 50sd .It feels like the keys try to push my fingers back , and resist , and after a while my fingers get tired .I tried to change the velocity , but it is just the matter of the keys physical feel.
I asked the seller to swab the keyboard with another pa600, but I think that unfortunately Korg has designed the keys on Pa600 differently, so they are a kind of unwelcoming to the fingers. I wished that the quality of the built of Pa 600 was the same as Pa 50 .
