LOL, it was me that posted that trick over at the AB forum 
Anyway, I was hoping the workflow would cover some more advanced possibilities other than just soloing a track or taking the whole mix as input. For example using some clever send bus trick or something. I witnessed a neat trick with Auria using the built in compressor for side chaining for example. Something that was faaaar from obvious (I still don’t get how the guy did it). Maybe there’s some hidden gem in the Cubasis routing that makes for similar routing or Audiobus ingenuities. Steinberg MUST have something up their sleeves here, don’t you think?
