Hi Mike. Been away for a couple of days. I do know a bit about the PA80, but unfortunately this is one area I know nothing about. I have never tried the video outs at all.
A lot of the reasons given here ( particularly Don M's ) are valid ones as to why some of the performing musicians "gave up" on the PA80. I don't like the 2 styles per fill either, and some of the fills aren't a good match to some of the style variations. I have not given up on my PA80 at all however. I don't perform live as often as some of the others here do, and I am one of the likely minority here who likes the OS and interface better than previous Yamaha and other arranger boards. I also dislike the key feel very much on the PSR line, ( but not so much the Tyros ) and I like the key feel of the PA80. While the PA80 has no vocal harmony presets, the harmonizer itself is pretty good and 16 user presets can be stored.
It all depends on what you like in a board Mike, and what you plan to do with it. I still prefer my PA80 as a live play board, but I have to admit that I could just as easily go to the Tyros. As a studio tool though, no other arranger works as well for me. It has editing capabilities that are unmatched in any other arranger, and some of the sounds I can make in it alone make it worth it to me to keep it ( I like using synthy sounds sometimes ). Any style can be replaced at will, so the board can be totally customized to fit your needs ( as mine is for my needs ).
Good Luck with it.
AJ
