I'm new to protools so bear with me. I received a session from another studio and I want to change the mix slightly to record some vocals then I will send it back to the other studio for a final mix. The problem is I can't get any of the controls to work on my system. The volume, pan, mute... none of the controls have any effect on the mix no matter what setting (auto read, write, touch, latch...) I have it on. The auto suspend is turned off in the automation controls window. What am I missing? The original session was done on a Digi002 LE. I have a MboxLE6.9.2.
