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,
