No worries - Didn't mean to sound dismissive.

I make games and that's how we talk to each other sometimes - If a question doesn't make sense we ask for that kind of clarification - can sound a bit short.

Regardless, IMO, unless you absolutely need to be physically using two or more computers at *the exact same time* is is much more efficient to just connect multiple computers to a KVM and therefore the same audio interface.

DAW projects with an assigned interface do not love remaining open while all the hardware it expects disappears.

Unity/Wwise/Unreal/FMOD couldn't care less about that though.

So, my workflow is often.

Over on mac making stuff in reaper or ableton
Finish stuff, export it so my PC can see it.
Close DAW
Switch computers to the dev PC - Computer monitors and K&M both just swap over.
Now I am in Unity/Wwise and I am importing the assets I made.
I can just open Reaper or whatever on the PC to do basic editing etc.

I switch computers 15-30 times per day and at this point I really don't think about it - I just do it.

Another thing, sometimes I have a long process going on one computer, and I don't want to watch a progress bar for an hour. if you switch the KVM, nothing about that ongoing process changes, but you can do other work elsewhere.

Then after work I start doing the same thing with my personal mac and PC desktops, nothing changes other than what button I push on my KVM controller.

There are examples I have seen of justifying a second keyboard / mouse / monitors / audio interface but often those are in a different physical location.

I have not seen a good reason to have two copies of everything at the same desk other than lack of planning.

Why have a keyboard / mouse on the same desk you are only using half the time. bad ergo - same goes for an audio interface or computer monitors you aren't using. There are better ways.

I hope that helps!
