hey guys! somewhat new here, but ive been a 7 year hardcore logic user! so i come to you for help....and maybe in the future i can help someone else! but anywho heres the scenario, im running an 8 core macpro with 6.5 gigs of ram on 10.6.4 with L9.1 im editing drums which consist of 10-12 grouped tracks, once they are edited (or sometimes mid way through the song) i obvously must merge the regions so i dont have 20,000 tiny regions bogging down logics already poor memory management system.... so ill go to merge and my KICK TRACK IS NUDGED LATE! its almost like when theres alot of regions on a track that must be merged, logic seems to forget it has PDC. the workaround is to bypass whatever latency creating plugins on that track....sometimes bypass wont work and i need to actually remove the plugin, and reinsert it. has anyone experienced this? ive heard on logicprohelp.com that there is a well known logic bug which causes merge region to act strangely when regions are too close to another. has anyone figured out what the exact terms of this bug are? and how i can avoid it without disabling all of my plugins.... and no "tell the drummer to play it tight in the first place" doesnt apply here
