Great, yeah this is definitely an area I know nothing about, and having these vocabulary items to search for is definitely helpful. Not quite ready for more feedback yet, though I've used the above information to clean some things up. There are a few places still where I can tell there's interference, but I'm not sure exactly what to adjust, and it's probably going to come down to a lot of experimentation and tweaking. So many decisions! Probably going to have to take a trip to the library or youtube to get more of a feel for what's involved on the audio engineering side of things, but this whole process has done wonders, I think, for developing something of an intuition for how an arrangement goes. Thanks again!
