I'm not entirely sure what the question is here, but a few thoughts:

I don't think we know if the RealDrums are recorded all in the same place, but I'm guessing they are not. My drummer has his own studio and produces tracks for clients located anywhere. He's played for Blood, sweat and Tears and was with Spyro Gyra for 14 years.

BIAB has some adjustments for reverb, both in the mixer and globally to determine the range that the mixer moves through. In other words, if you apply maximum reverb in the mixer, that could mean many things. The default is a little too much, in my opinion, and the first thing I always do is turn off almost all of the reverb on the drum and bass tracks.

Now guitar is a different animal, because they offer what they call Direct instruments, where you can bring up the guitar with NO reverb, and shape it as you like. You have this option in the Audiophile version.

One request we have made is for drum 'stems', in other words, to be able to have multiple tracks for each part of a drum kit. That might be possible in a future release.

Does any of this help?
