Hi KNFan,
Going by your continuing frustration with the Studio I'd say unload it, save yourself the ulcers, and do your best evaluations of the other top boards out there.
Being that you've had a Korg for the last while, you're probably attuned to Korg's way of doing things, so it would seem that the Pa1X would be well up on your list.
Good luck with whichever board you settle on - you know your health will be the better for it.
