Hello... As a musician, I like using my web cam and Presonus interface for recording songs that I perform. My Presonus has two channels, one for mic and another for my guitar. After a recording, I would like to add another track with another instrument, like a bass or fiddle or guitar lead break. Can you do this with OBS? I know PreSonus and others have have recording software (DAWs) that, as of now, are too complicated for me. And I think the DAWs are strictly audio.. no video. Any suggestions? Thanks... Tom
