It faired no worse than the Tyros3....Actually I tried to use the PA800 in my set up...The Tyros 3 didn't make the 3 day cut
Yeah, I know what you mean...the Tyros3, although very impressive, didn't quite appeal to me either....the Tyros4, on the other hand, did appeal very much, indeed.
Now I'm broke...but very, very happy.

I've never played the more recent Korg arrangers, as they won't bring them in at the local dealers, but I thought the PA-800 sounded terrific in the on-line demos. I did play an I-series (I think it was I-3), quite a few years ago, and it was really nice, although the OS took some getting used to...I do remember it had a wicked sax sound for the time.
Sound is such a personal thing.
