Tony, I think you are correct that it works technically, but whether it sounds acceptable is very much dependent on the style. By ‘style’ I mean what the individual RealTracks play musically, not the style you select for each BIAB song. Playing to a strict clave is an example. I also agree with what Tangmo wrote.

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.
