In an analogue mixer there aren't separate busses for each channel.
There are common busses to which each channel can be routed, typically
through a group assign switch or an aux send pot. What you described
in your original post was not how it's done in analogue.

I'll also echo some of the comments here about unusual techniques like
parallel compression. I think there's an overemphasis on such things
in magazines and on web sites as it makes an interesting (for some)
article. In reality they are rarely used. I've never used parallel
compression in 25+ years of sound engineering work for example, as
I've never needed it.
