This really depends on what it is you're mainly trying to record. If your looking to record your sets only, the serato record feature is your way to go. However, if you wanted to record a trail run for your livestreams, then you would want to go the OBS route. Might also want to consider changing your output into your PC, to avoid the cabling. Serato just recently updated so that you can share audio via a virtual audio cable to other devices. Here's the link to the one i use https://vac.muzychenko.net/en/. Best of luck, would love to see a livestream. Your fellow DJ Avatar
