For Joe V,

If you want, the TC in RB will allow the parts to be placed on separate channels. Mute the others and record one harmony at a time while listening to the un-muted harmony in your headphones. You will be 100% more satisfied with the end results. It takes a few minutes to sing each harmony part, but nothing beats real harmonies in a recording, IMO.

Well worth the time to sing them properly.
