BTW, I think it is a bit disingenuous to refuse to talk about why you returned to Yamaha, after you were SO vocal in telling us why you chose the Korg (and how much better it was, everything else was outdated, yada, yada, yada!).
Surely you aren't embarrassed to discuss your public backtracking? I thought you were bigger than that. Your reasons may provide very useful discussion, and perhaps help others make the decision for themselves. Hiding away in private discussion seems a bit locking the stable door after the horse has bolted. If you have any qualms about public discussion of your decisions, why did they not surface about the decision to go Korg, as well?
Inquiring minds want to know... LOL
