The Style also loads the feel, time signature, and tempo into the song. So generally, it is best that after you select a Style you are also selecting additional RealTracks that have these settings that are close to the Style. If you try to load a RealTrack thats tempo is very different or was recorded in a different time signature, then it might not sound the best. Other than these parameters, the Style does not affect how an individual RealTrack generates.

Best,
