Hi everyone hope you're doing well and staying safe. I want to use blackhole to route my system audio to Reaper, because I want to record some music production tutorials and I need people to be able to hear my screen reader as well as my voice. with my microphone which is connected to my audio interface. Please could somebody explain to me how I can use black hole to do this? Do I need to create an aggregate device to do this or multi output device to do this please? Thank you very much for your help everyone kind regards.
