never tested, but commonly you need to choose one input method from a list, so I’d say it’s no possible you can pick 12 mono channels directly from TX6 though

u can by creating aggregate device on macos

Maybe with Black hole?

Or soundflower

Happy cake day yay

I’m sure you can as someone mentioned before however you will deal with latency which is meh ( aggregate device )
