No, wrong. Just read what you wrote, and pull the Bus out of the equation, and you'll be half way there. Actually think of all this Effects processing, drum master, parallel compression, etc as AUX. Just think about it as Aux, i'll explain why soon...You have to know the ins and outs of what you can do with an AUX channel before you go to understand what a Bus is and how it works.
QuadWing, I understand your frustration. Man, that completely frustrated me at first. The only way I was able to fully understand this, was to use real world examples in my DAW so that I could learn. It's difficult for one of us to explain it, if you don't understand how signal flows and why you would need to use an Aux or Bus. Don't worry about VCA Faders, and Busses right now. Damn all that, you gotta take it one at a time.
First lets figure out why you would need an Aux in the first place. Then we'll move on to busses. But concentrate on AUX right now.
I'll give you an easy example:
Lets say you have a Kick, Snare, and High hat. 3 instruments right? Well you can send all of those 3 individual instruments to an Aux channel. Well why would you want to do that?
#1 Because you might want to put a compressor or reverb on them as a whole and not individually (saves computer resources)
#2 Because you might want to turn down the Kick, snare, and high hat the same level. Instead of going to each track to turn each instrument/sound down, the Aux channel has a volume control that you can use, and it will turn down the Kick, snare, and High Hat, all in one pop.
#3 Because you might want to mute the kick, snare and high hat. Again, Instead of going to each individual instrument to mute it, you can send all 3 individual instruments to an Aux Channel and just mute the Aux Channel and then you won't hear the Kick, snare, and high hat anymore. You'll hear other instruments and sounds that are playing in your session. Just not those 3.
Do you understand this so far? If so, I'll come back to the thread and explain more. I just need u to understand why you would need an Aux, and I promise you by the end this will make TOTAL sense, and you'll able to answer your question on the difference between Aux & Bus.
