I wouldn't be so sure on that one Donny. The best sounding keyboard in the world could sound like utter doo doo in the hands of a less experienced individual (Tyros 4 included).
Put this new PA model in the hands of Bert and let him do a pro quality demo for it.., and I think we'd be seeing and "hearing" the true ability of this new model.
Korg's problem IMO is that their demo team isn't as polished on using arrangers (as they could or should be).
and that speaker thing
