Thanks!
Disclosures - my room is wholly untreated, by necessity I do my mixing in headphones (dad, full-time job, 'studio' is in the home, not in a separate space) - in short, I am making do with a far from ideal set-up. I've done enough research to know I'm starting out from a disadvantageous point so I'm trying to find some ways to mitigate that.
I do a lot of playing around with panning and gain leveling, then EQ, then reverb, but looking for something like an EQ or filter for eliminating specific frequencies, tape saturation emulators, that sort of thing. The compressors and EQ in Sonar aren't horrid. Thank you for the the plug-in suggestions thus far!
Inscrumental music for prickly pears.
