This intrigued me -- I think the answer is that the
process is not linear -- you get sum and difference tones much as
in complex fm. I added an example to clm.html. Back when
Marc and I were first messing around with waveshaping,
I asked him about some way to set up the
poynomials to get a particular spectral evolution
as the amp increases (input amp being similar to
fm index in this context) -- you can use Chebychev polynomials of the
2nd kind to play single-sideband tricks, so it seemed
like there might be possibilities; other things intervened,
and I don't think Marc ever got around to dealing with it.
