[Csnd] FM/PM equivalence

Hi,

I stumbled upon Victor’s paper about Higher Order FM Synthesis and I am wondering if it would be possible to construct a null test that shows the equivalence of simple PM to FM. I’ve implemented both just now and, although the spectra look pretty much the same, for some reason I can’t make them null. Any idea why?

Cheers!
