<< For a modifier, what about something that basically does what a ring
modulator does (but not through simple multiplication obviously)---change
the spacing between harmonics plus or minus---but along a controllable
curve. Is that clear? I'm fumbling for language here. A ring modulator ends
up expanding or contracting the harmonic spacing in a linear way, and
because pitch has an exponential relationship to frequency, we get the weird
metallic non-harmonic sound. What if you could do something similar, but
with "curves" that could be voltage-controllable? As well as the deviation
amount? >>
ken,
while this is a "digital domain" implementation, something similar to this
idea is part of the music360 system they used to use at the univ. of padua in
italy. it involved multiplication with a variable ( and time variable, too,
if desired ) exponent factor to create complex timbres. apparently, it worked
pretty well.
so, maybe the hypothetical module could have a v.c. exponentiation factor ? (
multiply by . whatever to 1 to 1.5 to whatever else over a 0 to 5 vdc control
range.
best,
