Just made my first M/S recording with my new Busman BSCS-L, and now I'm trying to process it with MSED in Audacity (1.3.13 beta for Mac). The recording used left = mid, right = side which seems to be what most folks do. I did a "quick and dirty" conversion using the MSED defaults, and it sounds pretty amazing IMHO, but I think I got lucky. Lucky because when I recorded, I had the level knobs set the same on my 661, and the card (mid) signal was a bit hotter than the 8 (side). I just let it roll, figuring I would fix it in post, and like I said, it came out sounding amazing. Now I'm trying to see if I can tweak it and make it even more amazing. My question is, since MSED for Mac doesn't seem to allow on the fly monitoring, do folks make short tracks to fiddle with to get good settings, and then apply them to the whole show, or am I missing something and you can adjust on the fly? Thanks in advance!
