edit: whoah did not realise I am reacting to something from 2023 lol
How are you recording your mono bass signal in stereo, and why? 🤔
Why is the camera important? All cameras record audio in rather crappy quality and they are directly connected via USB, not a Scarlett.
If you have a Scarlett, isn't your bass plugged in directly?
I'm happy to try to help, I just don't understand your current situation 🙂
