The PA80 sounds interesting to me, but how is it getting along on only two fills? I currently own the PSR 740, and was counting on upgrading to the PSR 2000. With that instrument, I get four fills (each fill plays automatically when I press a variation button). Doesn't it sound a bit inferior to be hearing the same two fills throughout a whole song as compared to four fills? I wonder why Korg only provided 2 fills when their competition provide 4 fills. Outside of this, the PA80 looks like an incredible instrument just on specs alone. I haven't had the opportunity to play it.
