The RealStyles made for the Xtra Styles PAK use the complete RealTracks library that is included in the larger packages (UltraPAK, UltraPAK+, Audiophile Edition).

So, Xtra Styles PAKs will work when you have all 3,500+ RealTracks installed. Since the Pro version has roughly 590 RealTracks (and the MegaPAK approx 800), it would be incredibly difficult to find substitutions with the limited RealTracks & RealDrums included in that package.

That's one of the reasons we began developing the XPro PAKs - this way no one misses out on using new RealStyles with their Band-in-a-Box package. smile
