AndrewDwDrums

Hey everyone, I am having trouble recording while listening to already recorded tracks. For example, I have the drums all recorded on their separate tracks and now I am trying to add bass to it. My setup is a Behringer X32 rack and from that I have two monitor speakers. The only way I can hear what I have recorded is if I use the aux option which would be (headphones) in the playback devices dropdown. Whenever I try to record with headphones set as my playback device, it gives me an error message. If this makes sense to anyone and you can help me out, anything would be appreciated. Thanks!
