I listened to the Peter Solley styles. I ordered one, but it hasn't come via email yet. The site states that the styles have 2 intros, 2 endings, 4 variations, and 4 fills. Very good. Listening to the midis and checking the voices, the default piano voice is the Live! Piano, and the Cool! Jazz Guitar and Cool! electric guitars appear, so the styles were made on the PSR9000 Pro or Tyros. The styles don't sound as good as Yamaha styles, but some sound very good. If I like the one I purchased, I'll probably purchase another 4 or 5.
