The sine -> waveshaper mapping I talked about in the previous followup to
this mail isn't going to work (I think) because of the huge asymetry of
the output waveform, after looking at line-sine-fade Tim mailed.
It might still be possible with saws as the input, but then you have to
worry about phase shift was well :(
Dammit.
I think its probably worth a try with saws, at least it will make
extracting the transfer function simpler. I will try playing with
extracting a transfer function from a known nonlinear process and see how
much the phase shift messes it up.
