I disagree on one thing.... Real Tracks can and do change.

I have songs to prove it. In any given song, note the identifying number of the real track and use Real Band to generate that same exact track a second, third, fourth, fifth time and so on into a new track each time. Especially if that track is a SOLO track, you will end up with as many uniquely different generations as you have tracks. While the tracks will all tend to be similar, there will be noticeable differences in them that are useful. In other words, it doesn't simply replicate the recorded lick note for note each time. There's some kind of cool stuff going on below the surface that makes each track fairly unique each time it's generated. This is also evident in BB when you're using RT's.

Other users here as well as myself, have used this to good advantage in constructing a unique and well played solo or fills in song projects.
