Hey Don,
The E50 is mountains above my little KMA. I have to agree with Fran - the OS on the KMA is a real pain in the butt to use. I am enjoying it though because it gives me something different to fool around with between gigs. I have never really dug into any of the OSs of the keyboards I have owned so this is a new adventure for me. Besides - for the price you can't lose. Fran is correct on another point. The factory sounds of the KMA need a lot of tweaking to be stage ready. I found that to be the case with my PA1x and the PA2XPro as well. I was also looking around for a software program that would edit or help organize performances and styles on the Korg but I am told there are none. Go figure. I'll have to get to Shreveport and try out your PA3X.
