I hope it gives some idea to somebody
as u see it needs a Minihost Modular from Image-Line and a midi channel router (midiChannelize) from https://code.google.com/p/pizmidi/ u can add automation/effects to the different VSTi/outs using the Minihost nicely (although it's still beta) - ofc. I hope BWS gonna get official support for these things soon
have fun
