I can see how this VCA dubbing as a Folder can save on the number of tracks in a project.
I got into VCA routing a week ago thanks to this BRBWaffles's template:
https://forum.cockos.com/showthread.php?t=185672 (Note: there's a neat video on how it works, with great mixing tip included).
I may try to modify the template.
[edit] I just spent the last hour modifying my template. It works like a charm. I'm liking this new workflow. The VCA volume track is great because it is tied to my reverb and delay buses ( i.e. changes the loudness of the instruments track and the buss all at once), and now has the advantage of showing a loudness meter and hosting FXs if should need some (not that FXs should be needed once the signal makes it to this section of the workflow, but eehhhh)
Thanks guys for the insight, explanations, and examples. I took me a while to understand it all, but I'm there!
