How do? A friend of mine sent me 2 songs to mix but the each of the drum tracks are 1 stereo track- kick,toms,snare,cymbals,OH's everything. 1 track. I called him and he said theres no way they can retrack the drums because the drummer is going in for surgery and wont be able to record for a least a month or two. The only thing I can think of is to go through the track and build up a drumset by hand. How would you go about this situation?
