LJB...Now you have all your subbed tracks on one fader...
---like I already have on my Submix Bus fader. But now I can have the choice of looking at a console module on the left side of the Console's divider, or on the right side -- hmmm.
Ludwig, I don't mean to bust your chops. The trick you've described of setting up submixes in a different way obviously works better for you and it's your preference.
It's great when people work out personalized work flows that feels better to them. The particular motivation for coming up with alternate approaches may not always be shared or even understood by other people, but that doesn't matter. We need to work in ways that don't feel awkward or stultifying.
Not everyone's going to get it why this particular thing became important to you, but that doesn't matter - it works for you!
For me, a Bus is the same thing as a Track, only it's in its own neighborhood on the right side of the Console divider where I know I can always easily find it. Using Buses hasn't ever been confusing to me - tracks are directed to them, I do whatever I want with FX and routing - It's all logical and straight forward.
Even though I've never considered thinking that Sonar isn't capable of having subs on one fader, since it can, I can't say I've tried your method. Maybe with an experiment I'll see better why you find this better. Right now, it's like I said at the start - I have my sub fader either on the left side of the divider, or the right side. I don't see yet what difference it can make -- I can automate the faders in the same way, I can direct the output the same, add Sends, Solo the sub etc - I'm not grasping what the advantage will be. Maybe I'll find out!
