Support for multiple low latency audio interfaces at the same time (recording + playback)

Currently Studio one only supports one audio interface to be active.
I want to be able to use all my devices at the same time in the same setup!

I have two audio interfaces here:
- audient id4 (for my condenser microphone + phantom power for recording voice)
- RME AIO (for virtual instruments / general playback / mixing / headphones)

ATM it's not possible to really use them both in the same setup. Neither with low latency nor at all!

This for me would be a powerful improvement - to have multiple audio devices act in sync with each other in the same setup!!
Low latency audio of course! (buffer < 256 samples)
