In a message dated 00-03-22 16:17:18 EST, you write:

<< 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,
dave v.
