Tony,
Have you checked out the KorgPA site? http://korgpa.com/pa_root/en/news/news.html?en (manuals, demos, bonusware etc.) Listen to the PA800 (same sounds etc as a PA2XPRO) tutorial: http://korgpa.com/pa_root/en/support/tutorials.html

Also, check out the KorgPA forum at: http://www.korgforums.com/forum/phpBB2/viewforum.php?f=50

Lots to be learned here.
