I saw this unit on Musicians Friend. Anyone have any experience with it or with the control surface version? Also, I've never used any recording interface of this style. How would I use a compressor as an outboard effect either in post-production or for some type of stereo mastering (as far as hooking it up and routing the signal)? Four of the channels have inserts, but there aren't assignable outputs and line inputs (like on the MOTU 828). Is there a way to do it? Thanks!
