Yeah, Roger knows where i'm coming from here. Using busses etc is a slightly different thing, & trimming a section with a mouse, is again not the same feel as writing trim information with a control surface, whilst the track plays back.
I think this may be one of the last areas that it's lacking in ( & the way you can't undo a simple fader movement - Doh !)
If you want a VCA Fader, then bus all the vocals to an Aux Fader.
If you want a VCA Fader, then bus all the vocals to an Aux Fader. In the example you've just asked about the results would be the same, and the clutter would be no different than PT.
If you want to ride individual Trims like you can in PT, then select all the vocal tracks at once in the mixer, add the gain plug-in and then flip your faders. automate the gain and then when the producer says he liked it the way you had it mixed before bypass the gain plug-ins.
