yea bruce,  the source track starts at 0.

Just did a quick test - you are quite right. Control/Click on track volume, pan or gain sliders for quick grouping does not work with collapsed folders, even though the tracks are highlighted as selected when the folder is expanded.

Thanks for your diligence and comprehending Bruce.
 
The reason for this excercise was to see if it actually works so I could use the feature.
No, it doesn't work.
I expanded all folders, muted effects buss,  
bounced a mix (80 or so tracks)
muted the bounced mix
brought level down 8db on all tracks
bounced a mix
lowered volume of first mix 8db and inverted phase of first mix
played the 2 mixes together.
doesn't null. Not even close.
 
Also, I shouldn't have to mute the effects buss as all sends are post-fader. It's 1's and 0's after all. (edited per Bristol)
 
If you get a chance Bruce, it would be great if you could confirm. Thanks
 

If all sends are Pre-Fader then you are doing nowt to reduce the volume going into the bus.
 
Your Fx should be running Post-Fader if you want all volumes to drop when you lower the fader
 
It's 1's & 0's after all..................

Sorry Bristol. 
You are correct.
I meant post-fader in the other post.

No worries

I will give it a try in the studio Tomorrow Tim. Just a thought though; I am not entirely sure that it should null. I could be wrong,  but I think unless all tracks start out with their faders at 0 before any grouping volume reductions the mixes of the two files will be different. Using the control/click grouping,  you are reducing each individual track by 8db, thus changing the ratios between them unless the faders were equal to begin with. By bouncing the track first and then reducing the entire mix by 8db, you are changing the level of the overall mix, but not the ratio between individual tracks.
