I just recently purchased expansions BFD. And am having all kinds of problems. I'm running 6.4le on a G5 running Panther 10.3.3 with 2 gigs ram, using rewire. Sounds are great yet using to track is tough. Maybe I'm just clue less. I'm getting all kinds of memory problems! Go figure. Cpu power usage is cranked and still. What's up? If I put a click track on along with BFD.......Pro tools blows up !! Forget trying to track the "grooves"....everthing goes to hell, I get maybe a 1/2 a bar before it stops. Any help would be greatly appreciated.
