Well, well, this is something I will have to dive into more so as to get a concrete answer. I believe the hardware would probably be the same - any variations would be in software, particularly in the SOUNDS department since there are different 'tastes' for both the European and American markets. Just the 'Piano' alone calls for a difference as it is obvious that the markets are not the same ... even car companies adjust their product to suit demands in the various areas!

As of now, I do NOT know for sure if there is a difference but will surely get some response by the end of the week. I believe a comparison b/w one bought from a dealer here in the US versus one imported from synthplanet should do.
More on this soon.
