I think Korg have been having substantial Quality control problems in the new set of Pa keyboards from the PA800 to the PA 2X. I cant remember a time that i have heard of so many hardware problems with the Korg in a long time before these models. I think they have probably cut one or two corners too many in an attempt to reduce their build costs. To be fair my Pax has only given me a few problems but i gig heavily with it and throw it around a bit when packing away and setting up so it has stood up pretty well considering the heavy use.
