I have a MacPro, Logic 9.7, a MOTU Traveler and some decent speakers and mics. I have some perpetual problems. Number one is finding a high enough level that will not clip, yet will allow the singer to hear his or her voice with the music without having to turn the music way down. Is a headphone amp the answer? If so, how do I get separate headphone mixes from Logic out into separate outputs on the headphone amp? If these questions reveal a lack of basic understanding, so be it. I have to ask them. I am also trying to understand comp tracks. It drives me insane. I've watched tutorials, I've tried to commit to using them, yet I find myself confused within 4 or 5 takes as to where things are, afraid to flatten and/or merge and just end up creating extra tracks, recording different sections several times on different tracks. At least I can understand where everything is that way. I never feel as though I know where I am when I come back to a comp track with a bunch of takes on it. Does anyone have any suggestions on how to gain more clarity and effectiveness with this tool? Thanks!
