Setspectraldiffraction feature request

Hi Robert,

is it possible to make the setspectraldiffraction working also for negative numbers?
Let’s say like the distortion exponent of an harmonic series: if you put this exponent to -1 you have an inverted harmonic series.

Fn = F1 * n ^ exp
where F1 is the Fundamental, Fn the frequency of the nth harmonic
with exp = 1 the spectrum is harmonic
with exp > 1 the spectrum is dilated
with exp < 1 the spectrum is compressed
with exp -1 the spectrm is inverted

It would be interesting from a timbrical point of wiew
