So my first round of framing is done on my new build (pictures will come, I swear). My contractor and I were laying some things out/ordering materials when I asked him about the gaps between the rafters of our roof. He explained that they're to let fresh air in/moisture out, but they'll be covered by soffit material on the outside.
My wonder was:
If I plug those gaps with wood will it cause serious moisture problems (I'm already going to be pumping fresh air in to the control room and live room since they're sealed)?
Will soffit material be enough to contain the sound of the outer layer of my room-within-a-room design?
Roof soffit, weak link?

You need venting. Moisture leads to mold. This is for the attic space, not the room itself. The soffit vent pulls air in at the eave, which vents out at a gable or ridge vent. Plywood soffit with vent holes is probably going to contain sound better than vinyl soffit - these are the two most popular options. If you have attic space, it might be possible to design a more convoluted system that satisfies the same requirements.

Typical Vented roof scenario shouldn't be much of a problem as far as sound transmission goes. Your room within a room and attic insulation should cover any real world sound transmission concerns.
Taking the roof venting of the equation could pose problems.....unless that roof insulation system is redesigned to be a "hot roof". Which basically means that the insulation between the outside and your ceiling is sufficient enough to never allow the heat in your house to reach the shingles (outer roofing) and cause melting/moisture buildup. Generally this requires a blown in foam insulation type to create that perfect seal/moisture barrier.
If you've already got a vented roof system set up and have any budgetary concerns at all, I'd say you'll be A.O.K.!
