This sound similar to all the strange audio mixdown issues I've seen where the output setting mono vs. stereo or direct causes a difference of 3db when summing stereo stems. To review if I'm set to mono on output then the sum of two stereo music tracks etc... will require a -6db audio mixer setting to compensate properly for the summing. Doing the same thing with the output setting set to stereo and the resulting audio mixdown requires a -3db audio mixer setting for the resulting track to maintain the proper summed level and the behavior is the same when in direct. I've yet to figure out the change in behavior but I speculate it might have something to do with the addition of stereo tracks but IIRC those existed in 5.5 too so why the different behavior in V6 and above?
