However, maybe I just don't "get" it
I'm in the same boat. I do not get the love-fest for VCA faders in a DAW. Maybe it is just the name VCA and the reference to a console it calls up, but I can't work out what is so special. Near as I know from having used them in the real world once or twice is that what they do is move things with relative offsets so they maintain the dB spread between them.
Ok, great... I can think of like 4 easy ways to do that in a DAW with no problems. A group in Sonar does it easy enough, for that matter assigning a bunch of things to a bus would do it just fine, just without the fanciness of the other faders moving.
I feel like I'm missing something based on how worked up over them some people get but I can't figure out what even after thinking on it. It was a big deal in the analogue domain because you literally had to have a console designed differently: Where faders controlled the voltage level going in to an amp, rather than directly attenuating the signal itself. However that's all irrelevant in the digital domain. There are no faders, no amps, all this stuff is just widgets to help us tell the software how to do the math it is doing.
