Let me shed some light on the sample loading issue.
I received my order of PA2Xpro's and PA500's yesterday. Since the PA800 came out with version 1.02 or 1.03, there has been a note when downloading the directions and new benefits telling users to delite the global folder when loading any sets made previous to this version. Then, once loaded, you can save this set on your thumb drive or hard drive. If you don't do it this way, you chance having lockup problems.
I have now loaded over 10 sets of different samples and multisamples into my PA2XPRO on the sales floor without any insstances of locking up. For those of you only playing western styles and sounds and never load samples into the keyboard, you won't know what I'm even talking about. For many middle eastern musicians who load custom sets of iranian, arabic, etc. sets of styles and loops, you must follow these directions and you'll have no problems.
