Hello is there an easy way to add a separate buss for heavy compression? But still keeping my dry signal easily accessible. I have tried a number of ways, but I must be missing something really easy all I want is a duplicate track ( say as a drum group) which I can add compression to then mix in with my original drum sound. But keeping them both separate? Any help gratefully received 
There are several ways, it all depends once again on the used software…

Cubase sorry
You can use the Maximizer. It has a “Mix” parameter that you can essentially do the same thing with. I do the vintage comp with like 1db GR, the infected mushroom for master limiter, and then to add extra loudness, I put the maximizer on like 20% and then the mix on like 30%. works very well that way.
I could NOT see where you can add another stereo bus out in Cubase Artist 10.5
