I know with my PA3x KORG had the dual smf player although awkward to search, load, use live it did work to a point..
Donny ... I don't know why you found the KORG dual smf players awkward to search, etc. ... On the Pa900 I don't find it difficult at all ... just as easy as going from one 'style' to another ...
However, I do find it exasperating sometimes to have to make sure the player is stopped before going to a style ... but nothing is perfect ...
