Not sure if this is possible, but when recording/printing mixes to new track, I would love the ability to select multiple in and out points throughout the timeline to create a "Recording Queue." I think this could be particularly valuable in post production workflows, where multiple versions of a mix may be created within one session.
Example workflow: you're mixing a :30 broadcast promo, and there are 6 versions—all basically the same, except for the VO tag at the end. You have all 6 versions laid out in the timeline, one after the other:
01:00:00:00 - 01:00:30:00
01:01:00:00 - 01:01:30:00
01:02:00:00 - 01:02:30:00
01:03:00:00 - 01:03:30:00
01:04:00:00 - 01:04:30:00
01:05:00:00 - 01:05:30:00
By adding each in and out "timeline region" to a "Recording Queue," you could press Record just once, and Pro Tools would record each 'timeline region' in succession, including any pre/post roll.
The concept is "measure twice, cut once" across an entire batch...instead of "measure, cut, measure, cut, measure, cut, measure, cut, measure, cut, measure, cut..."
I believe this would also be useful in ADR/Foley recording scenarios, or even music tracking. Need to add tambourine to only two bars in each Pre-chorus? Set up the recording queue and let it rip!
