Cakewalk Home Studio 2 ========================= I imported an mp3 file of music to track 1. I recorded vocals on track 2 with a microphone. When playing back and listening to track 2 by itself, (with the mp3 music from track 1 muted); there is the presence of the mp3 music from track 1 mixed in with the vocals on track 2. When recording, what do I have to do to create separation between tracks? (The sound card is a Santa Cruz by Turtle Beach which is a full duplex card.) Thanks.
