One way to get around the locking issue of importing tracks is to put a test tone on the front-end of each tape or song. I believe that the Mackie 8 buss come with a tone generator, I could be wrong. Using either ADAT or DA's you could get the tone pretty darn close to lock up in ProTools. I seems like a hassle, but nothing's perfect. Let me think about it some more and I'll get back to you.
