Why is it that in Realband the demo songs sound different than in BIAB ?

To demonstrate what I mean: In BIAB I choose the demo for the style _JEGTBAL "_JEGTBAL Demo - (ALL REALTRACKS-AcBass,ElGuit,Ballad60.SGU)"

When I hit the Play-Button a smooth pattern is generated and played. The basic motiv of the pattern will not change, even if the song gets regenerated pressing the Play-Button in BIAB again.


When I pick now the same Demo song in Realband (Realtracks are generated) the song sound very different than in BIAB even though the chord progression is the same. I can regenerate the realtracks many times, still I can not get the same rythmic pattern as in BIAB.

Can anybody tell me, why is that? Is there any trick to have Realdband play the demo song in the same way as in BIAB ?
