I wasn't sure how to properly search for this one (being a multi-part question) but I also figured i'd get a better response from starting my own thread. I've run into a problem here recently when mixing a fast metal song that I wanted to ask what a good way to trouble shoot it is, and what people have done in their past experiences.
The Scenario: You're working on a relatively fast metalcore song with a lot of 32nd note kick and picking patterns. The song also happens to be in a pretty low tuning... drop A# for this particular one. The mix is meant to have alot of "bottom" to it since it is a band that primarily plays "heavy" breakdown style music, however they occasionally speed things up and attempt at playing semi-decent sounding traditional melodic metal riffs. The problem with this however is the bottom end of your mix (particularly the kick) gets sucked out by any low-band/general compression and you are missing the "punch" whenever those 32nd notes kick in... all smack and no balls.
The Quesion: To avoid this and regain the songs "balls" would one consider using time compression expansion to slow down the tempo of such sections on a DI guitar signal that has already been tracked? Or would that cause bad artifacts? (The drums are being ran through a program so those are no worry to me). OR is there a secret to keeping the thump of the bass drum consistent throughout the song no matter what speed its played at??
