Hi--
The math is elegant, yes, but the plugs (and app inserts) I've tried
do not seem to be designed to undo the math except at unity
settings-- that is-- when no adjustments to the stereo field are
made.  Everyone, probably Adam who started this string, agrees that
its preferable to use one's original field files, so, for me, its
pretty much down to the pursuit of phantom plug settings which I'm
happy to entertain off-list. :-) Rob D.
