Firstly, I'm a recording engineer that does video. I have a full featured recordings studio and find OBS audio options to be a little confining (or maybe just confusing) to what I'd like to do. I do have a hardware mixer and that's how I'm handling my audio stream mix. At the very least, I'd like to be able to select exactly which inputs on my interfa ce I'd like to feed the stream. I'd also like to be able to insert a software limiter https://tweakbox.mobi/ (vst) on the stream output. Is there anything like that? https://tutuappx.com/

OBS has two versions of my interface available but they both give the same limited options. I see MOTU Pro Audio and MOTU Pro Audio 1-24. Both of these only see physical inputs 1 and 2. I cannot choose some other input for a source if I want. https://getappvalley.com/
