So I have read some articles online, and one small thread on this forum on this topic. I will be completing a project that is for vinyl and digital release. It seems a good idea to make sure you don't have a ton of presence on tracks as well as bass. Especially sub. So what is the workflow hear? High pass everything appropriately and get a good mix this way, and don't pan kick or bass drums? Should I help out the mastering engineer and do some M/S eq'ing to remove any excess low frequencies from the sides? Should I also low pass things? How religiously do you guys follow this code? What else is there to be aware of? Thanks all.
