I have a audio interface with two XLR inputs, in the V2 version when you selected the combo input device as the input in Voicemod(in this example being Berhinger 1-2, meaning both inputs are hot) it was able to record audio from both mics simultaneously, I don't get why they got rid of such a convenient feature when it already existed in the previous ecosystem. I reached out to someone around the time V3 launched and they replied with it being future thing but it neve came, unless I have a setting messed up or something.
