And here again, we come into the differing marketing angles of Yamaha and Korg. It's widely accepted that Yamaha are not interested in selling to 'tweakers'. Much easier to get their intended 'home' players to pony up the cash for an all-new, shiny, OOTB unit. Dedicated Korgies are still finding tweaks in their i30's, Pa1X's, 2X's, 800's. Horses for courses, and all that.
