<<< Let’s say I went into the studio and recorded a trumpet solo in 4/4. My employer edits that to take out every fourth beat because he or she decided to change the song to 3/4. Will it work? Maybe, but some measures definitely won’t and will require tweaking. Now let’s consider a comping piano or guitar. What are the odds that truncating what they played will sound good? Even lower. I think it’s remarkable that this works at all - musically - in BIAB. Now, if I had gone into the studio knowing that my playing might get chopped up like this, I suppose I could play differently, but it would severely hamper me to play well. >>>

Matt's statement above is the very essence of thinking how BIAB RealTracks operate in my view. Imagine BIAB tracks being Played by a live studio musician in your studio, on your project. After your session player is gone, you can do anything with a BIAB RealTrack that you can do with hiring or otherwise having a 'live' musician, other than yourself, participate in your recording project. But, you also have the same limitations with the circumstance the recorded audio you have, regardless of the quantity of that audio recorded for your project, is what you have to work with. It is what it is. Just as Matt mentions above, if it wasn't recorded, while there may be limited leeway in manipulating that audio to do something originally not thought of, or intended, it is a brick wall limit.

For me, there are three principle reasons and benefits to using RealTracks in a studio, whether home or commercial, hobby or professional. First, it provides an instrument one cannot play, or can't afford to hire or conveniently get into the studio on short notice if facing a deadline.

Second, someone may play a particular instrument but are not as proficiently as a RealTrack session audio can produce for your recording.

Third, one may be proficient musically to play an instrument themself but it is inconvenient to do so. Examples would be an acoustic piano that's badly out of tune and no access to one that's in tune. Setting up and multiple mic the drums and then having to tear down the drum kit or not having a permanent, studio setup and having to take time to get a guitar and amp from a storage area, setup, tune and afterwards return it all to the storage area. All for an 8 bar guitar solo. It may not be worth that effort.
