Does it function at all if you have a vocal track that has harmonies, ie nothing but two voices? Or will it just say it’s somewhere in the middle of the two or something.

 

It will give you the main harmony. It also works for any other instrument obviously and it works even if the vocals aren’t separated, although obviously it will be less precise and it will depend on how much stuff is going on beside vocals.

Your mileage may vary – it doesn’t *always* give the main harmony. It just sorta picks one. And it often flops between them.
