I purchased a PA60 about 3 weeks ago and i have been extremely pleased with it in virtually every aspect of it. I initially bought this as a 2nd keyboard to go with my X1, but i have been using the PA60 much more than my X1 recently!
The styles are excellent and amongst the best i've ever heard (and ive owned virtually every make of keyboard at one time or another), they are certainly very realistically arranged and sound real. They even give some of my X1's patterns a run for their money! The PA's styles are very professional and have been arranged to suite so many types of music. Most of the intros and endings are excellent and stand out in a big way. Its one of those keyboards where you can select a style, and bang, you immediately think of a song you can play with it, and when you do, it sounds very believable. You asked about fill ins, it has only 2 which is a little surprising, but i think they are acceptable.
The sounds on the Korg are very good as well, obviously some sounds are better than others which i guess is the same on every keyboard. My favourite sound on the PA60 so far is the Jazz Guitar, it sounds so much like one. Synths and strings are excellent as they blend in with the music very well. And thats something ive noticed with the PA60, the way sounds blend with each other, seems so balanced and mellow sounding, where as some other keyboards can tend to sound harsh at times unless you adjust certain effects and volume. The Korg is virtually spot on with its balance leaving you very little to do in the mixer whilst playing. I have not been through all of the sounds yet, im still feeling my way into the keyboard. Put it this way, this is how good i think it is: Previously when i used to own certain keyboards, on some of them it took me about a day or 2 to go through all the sounds and styles simply because i would hear something and soon bypass it thinking "yes its ok, yes not bad, yes its passable, yes its usable" without finding anything actually attractive or exceptional, and sometimes it becomes forgettable. With the PA60, especially on the styles section, i keep having a "wow that is amazing" feeling, and i tend to go back to the same style and play something else with it, and it goes on. I have not even been through all the onboard styles yet so i can't wait to see what else is in store for me! Thats how good this keyboard is i think.
Some of the sounds that really stand out are:
Guitars
Strings/Synths
Electric Pianos
Accordions
Again, i have not really tried everything yet to the extent where i can comment on them. Saxes sound fine when browsing through them, but not used them enough to judge.
Possibly the best feature of this keyboard in terms of sounds are the drum kits. They are very realistic, and im some cases outperform some from the X1.
My favourite style so far is HalfTimeBld, simply awesome to perform with.
As for the Harmonizer, someone like Uncle Dave can possibly answer your query as i dont have it installed on the PA60 (if it actually can be that is).
Overall though, I am very pleased with the PA60 because its certainly given me far more value for money than i first thought. Its fairly easy to use, the only thing i didnt like about it is the mixer, its pretty fiddly. But you get used to it i suppose. But when your getting quality of its kind, i tend to forgive its shortcomings!
Unfortunately, i cannot comment on anything regarding the PSR2000 as i have not used anything by Yamaha since owning the PSR8000 5 years ago.
Good luck with your findings!
