Yep...that worked. (moving the mic)
I had to bounce it down to one track so I couldn't pan them.
Weird.
I noticed the same thing doing harmonies on vocals too so hopefully it will work on those too.
Thanks :)

I don't get how to invert the phase of one of the tracks though. Could you explain? I'm using Cubase SX so maybe you can only do that on a hard disc recorder?
