I agree with Noel. I think the answer may turn out to be that the Elastique algorithm that is used now for pitch could have replaced the need for those files. I recall there used to be an option in the RealTracks preferences to use or not use what they called the +- files, something like that. Please post here whatever you learn from PG Music.
