Gadi, take a look in your RealTracks folders.

You will find .wma (or .wav in the case of Audiophile edition) tracks for each RealInstrument you have.

Note that there are typically THREE identical tracks but in different keys. These keys are typically arrayed as a diminished triad, or to put it in another fashion, they will be stacked a minor third apart from each other.

BiaB intelligently picks the one needed to fit the key you have designated for your songfile and then uses pitch stretching algorithms to put it into the exact key desired. If, of course, the key you happen to pick is the same as the key of one of those three root files, no stretch would be needed.

Three files of identical playing with the key signature of each spaced as to a diminished triad yields enough spread to always have one of those keys "in reach" of the stretch algorithm. This prevents having to make the algorithm stretch the key too far, at which point digital artifacts and other undesirable things that are detrimental to the fidelity occur.

You can play back any of the "root" RealTracks files using a media player like the Windows Media Player. Worthwhile to do this, as it opens up to you what's going on a bit better.
