I think you are right on this. A while ago I create a stereo version
of perfly that used the Fakespace Boom. I had found that FOV wasn't
really "shared" across channels as documented. It might seem so
only for the default 45 degree FOV but other values show that there
is a problem. All "shared" FOV's not explicitely set will be 45
degrees regardless of the "master" channel FOV. This was in
Performer 1.2 btw.
