The Pa800 styles are way above the rest...listen close.
with a few tweaks & edits here & there they are so useful in so many ways.
To busy is a personal thing.....with an arranger KB you can make the styles as Busy or simple as you want, or use converted ones or make your own to suit your needs a process very few do.....or just play LH bass and piano if you want simple...who the heck listens to these so called claims? I surly dont.
