Just an excerpt from the PA2x manual ...
Patterns/Chord Variations : Up to 42 patterns for each style including 3 Intros, 3 Endings, 3 Fills..So I have misunderstood what the info was saying and thought it meant 3 per variation...but I still thought the fills sounded different on my old pa1x, and the PA800...anyway I'll soon know for sure...
