wondering what a block diagram of this synth 
would look like. as in, a kind of signal flow 
diagram or something like that.

just wondering about theoretical possibilities
(and impossibilities) for future ideas;
for instance, taking separate harmonics and 
rerouting them, ringmod options, stuff like that?

i'd like to know more about what's going on inside, 
how it compares,say, to juno's jp's and jx's. some 
kind of assessment/description of the osc+filter etc. 
circuitry.
