not sure we're talking about the same thing. when i have a RealBand file I can assign several tracks to a subgroup - usually the fader on the right gets named g1 which means i can rasie or lower the volume of all the tracks with one fader.

its g1 i want to record the moves on and i think i've seen a post that says you can't record subgroup fader moves. A1 is the main output so I wouldn't change that anyway
