is there any way to make a special track in vegas specifically for drawing volume and effects envelopes for the master bus? ie, there wouldn't be any audio on this track, just envelopes. a simple usage example would be to draw a master fade-out curve at the end of a song.
In acid you can have an automation track for the master bus as well as other busses present in the project which is really nice. In Acid 4 you can also automate every plugin parameter which is pretty nice,
Track/Bus -->Bus --> insert FX --> Fader ---> Bus/Hardware assignement
This is like any hardware mixer insert that I have ever used. (I am looking at a number of signal flow diagrams as I write this for some of the mainstream small format mixers and even a large split console.)
With the assignable FX, there is an additional fader/gain stage:
Track -->Bus ---> Input Fader ---> FX ----> Output Fader----> Bus assignement
This is modeled after the typical AUX Send/Return model. The "input fader" is your consoles AUX Send fader that is fed to your external gear. The "output fader" is the return gain on the console.
Why do you want the insert on a Sub bus to be POST bus fader? This would be like routing the direct sub out of a mackie 8 bus to an FX.
"With the assignable FX, there is an additional fader/gain stage:

You got it right here Peter and the bus insert is correct in V4 also along with the master bus automation being in the correct location also. the "Input Fader" as you're referring to it here is actually the "Aux Send" and then the output fader is the "Aux Return". This one got by me in V3 beta testing because I hardly every put any FX's in my buses, but Pipeline was correct when he pointed it out that it was wrong in V3.
