Donny, Scott et al,
The fill to repeat is like some of the other goodies in the PSR2000 in that, if not careful, you can over use it. But, since discovering this feature I have programmed it into some of my more rock oriented songs..."Brown Eyed Girl" and Rod Stewart's "This Old Heart of Mine" to name two. It really does add some adrendilin when used in the right places...plus keeps your hands on the keyboard without having to punch the variation buttons.

And for some of your latin songs, try setting your pedal to "Percusion" and adding in some real latin flavor. These are nice little spices for your musical recipes.
