Not sure if this has been covered.... but proper routing for time based processors i.e. delays and reverbs. create aux track, insert your processor of choice however you want it with the mix at 100% On the tracks you want routed to the aux track, use sends to aux track then adjust the send levels on...

Here in Charlotte, NC there's a free monthly show put on by Mind Elixir called "Bass Church". Sadly, it's not strictly dubstep... but Mind Elixir always plays a dubstep set. A little heavy on the midrange shit, but if you're looking to see some live dubstep, it may just satisfy your needs....
