How do you make an Work around with a DAW for this? I've used VST Plugins to route audio to Reaper.fm DAW and back. But there is a time-lack around 500 milliseconds. That's too much and it does not seem to work stable enough.
You don't route out of OBS and back in again. You connect everything *directly to the DAW*, so that OBS never sees it at all, and only pipe the final result from the DAW to OBS.
That still has a risk of adding a lot of latency between apps, which is more Winblows' fault than anything else. I think it's far more likely to find a way to bypass the OS processing (and delay) from DAW to OBS, than to try and make OBS do anything beyond a dumb passthrough of the final result from something else.
is it possible to write an OBS Plugin for adding an audio-master Channel? Is there such a plug-in already out there somewhere?
All I know of immediately is this one:
This plugin provides audio transmission source and output using VBAN, an audio over UDP protocol. VBAN is a protocol to transfer audio over ethernet built in VoiceMeeter. Using this plugin, you can directly receive audio from and send it to...

I don't use it myself, but it looks like a possibility at least. It connects to VoiceMeeter, which is a very pared-down "DAW-Lite", if you will.

Two different sizes of the same thing.
Being very pared-down, VM doesn't have all of the features that are really needed to do *everything* in it, and so you'll probably end up with a mess of different processing in different apps because none of them have a complete set. I did when I used it with OBS. I use Ubuntu Studio Linux now, which comes with OBS and a full-blown DAW that really does do EVERYTHING, both preinstalled and already working, and it's a LOT nicer!

I still had to make the connection, but the tools for that are preinstalled too.
