OK... this forum does not work as well as others in my experience. I have no idea why it doesn't refresh and show you the post instead of have a "you posted successfully!" page, which is eventually followed by a "NOT!"

What I was saying was that I've heard all sorts of sampled rhythm guitar and it seems that nothing approaches the realism of RealTracks, at least IMHO. There are some great loops but that is all they are. RealTracks is far more than a loop and provides the slight variations and subtleties that one might expect in a real player. No, it's not perfect and there are times that I want to use it exactly as some of you suggested -- muting out the autogenerated track and replacing it with my own, e.g. a specific fill for four bars that may go to a cappella.

I was originally told that you cannot access any MIDI from any Real Tracks because they aren't MIDI - even though there are charts. I said I didn't understand this at all since the data seemed to be there. I guess there is a convoluted way - but it is useful (even though I know I can't edit the Real Tracks as if it were MIDI.)

Anyways... I thank you guys so much for helping me understanding how to approach BIAB and RB. It seems like the perfect tool for musicians to do "rapid development" and then fine tailor the parts to your need after generating what you need. Much in mastering will be in the approach. All these great tips so very welcome.
