Cool, I wonder if a PIC processor could handle the job...

ken,
well, many years back, my friend jack deckard had implemented it on a 
"singleboard" micro ( a paia 8700 ) and liked it enough that he worked
out 
some of the details for making up a v.c. module to do it. he had an
article 
on some of those ideas printed in "polyphony", so there is some info on
the 
subject out there......
even such a rudimentary setup produced amazing plucked tones and if you
fed 
real digitized sounds into the memory, it produced some strange effects.
jack 
didn`t do this if i recall correctly ( gotta dig out that magazine ! )
but i 
had read about others using the technique in a more computer oriented
setting 
doing so ( like paul berg formerly of the institute of sonology in the 
netherlands ).
best,
dave v.

ken,
i would certainly think so given that good results could be had with a 
500khz. clocked 6502 !!!!
what about it, pic guys ?

  440KHz, actually. :)  I have an 8700 along with it's whopping 1K of RAM
and ROM.  A PIC could probably do this, but I would be inclined to use a
micrcontroller that can make efficient use of RAM.  There are several in
the PIC family as well as my long-time favorite Z8 family that work with
external RAM.  RAM can be made to work on kust about any PIC, but the ROM
space is finite and I would not want to use the bulk of it to operate a
RAM interface.

crow,
only 440 khz ? gee, my memory is slipping ! still, for what it was and when 
it can out and what it cost, i got a LOT of musical stuff out of that machine 
!!!! 
okay, pic, z8, 8051, whatever....... can it be made up into a cost effective 
v.c. module ?  again, i would think so but i`m not an engineer........
