find...a plugin...that could control volume without using the fader volume for the envelope.
Empty FX Chain
Ah... yeah. That's the way to go. The vid I learned that trick from preceded the FX Chain Modules with the independent input/output controls.
REZA... do as scook (and I said) and insert an empty FX Chain module into the Prochannel (wherever it is most advantageous in the signal chain for the volume changes to occur... like at the very end of the PC chain) and automate the output control on the module instead of your volume fader.
No need to bounce or do anything at that point.
Cheers.
PS: Based on my (admittedly limited) experience with Offset Mode it seems to be more confusing/hassle than it's worth but yes, that is of course an option.
