I'm new to recording directly into Pro Tools. I have had PT 8 LE for years, but always used a line 6 UX2 with Ableton to record, then exported into PT. I just this week bought an Mbox 2 from a fellow Sneapster, and I've been having some problems getting it running smoothly (thread here if you'd like to help!). But I am curious about recording into Pro Tools in a session that already has lots of plugs going. I want to record vocals into a session that is near a final mix. Is it standard to have to print everything else previously to recording more? I only ask because I know for latency you have to change the hardware settings , CPU etc, which I assume would disable most of the plugs. So do I need to nail down final tones and print everything?
