This has probably been asked a many, many times, but I just can't figure this one out. When selecting a track to record in Studio One 4, I'm getting a doubling type of sound on the vocals. Happens when monitor is selected on the track. When deselected, no vocals can be heard. This is in a headphone mix coming from my Scarlett 18i8 interface. how do I hear a clear sounding vocal when recording? Thanks for any input.
