Russ,

I think that once you get your backup harmony vocals recorded, you'll be just fine using your BIAB mix on your laptop. K.I.S.S. Principle.

As for “Mixing” - I would mix through your PA, just as if you were playing live. A mix done on stereo speakers or even good monitors is not going to sound the same through a PA, for a variety of reasons.


Regards,

Bob
