okay, so I'm thinking there must be a simple way to do this but I'm missing it somehow..I was reading this article http://www.soundonsound.com/sos/dec09/articles/logicworkshop_1209.htm specifically, the section with the heading "Align Tracks" which talks about pulling room mic tracks into alignment with the rest of the kit and then applying a sample-delay plugin, the purpose of which is to avoid artifacts during flex-time quantization. So by blowing up the view of the drum tracks in the arrange window it's easy to see how the room mics are slightly delayed compared to the close mics, and the article suggests opening the sample editor and removing that amount from the start of the left and right room mic tracks. So, since you can't see the other tracks in the sample editor to visually line up the cut, I'm thinking that the way to do this would be to make a separate section-the length that I want to remove- by cutting the track in the arrange window, then open that bit in the sample editor to see how many samples long it is, write that number down, then undo the cut I've made, open the entire track up again in the sample editor, remove that number of samples from the top of the region, and then repeat on the other room mic. Problem is, because they are two separate tracks (from a Pro Tools session) I can't take the same number of samples from each one-apparently Logic looks for an appropriate spot to cut and while somewhat close, it can be a hundred samples off. So I guess I have to bounce the L & R room mics to a stereo track and do it that way. Even so it seems pretty convoluted. The other, bigger issue is that the edit in the sample editor is a destructive edit, meaning that there is no possibility of trial-and-error, adjustment, etc...it's really easy to make a fatal error using this method. I was working on a copy of the project-I know better than that-and I know I could make copies of the room-mic files also, but it's a PITA to go through the process of importing the original file every time you do this and want to un-do it. So, I'd be grateful for suggestions from anyone who's dealt with this-thanks!
