[sdiy] all analog FM synthesis?

I wouldn't; I would use the A/D -> microcontroll -> D/A to do
sinetable lookups. So it would basicly become a digital PM synthesizer
with analog PM input :-( Still, you'd be able to hook external gear
into the PM chain FWIW :-)

As far as I can tell, I wouldn't, that's what my post is about... ASSI
suggested a simple solution to the problem of analog signal wrapper
would be to use an ADDA solution.

Btw, I'm to silly to understand your saw phase shifter. It doesn't
work with anything else than a saw, does it ?

How is a modulus function (if it's not called modulus in english, I
mean the function of getting the rest from an integer division) done
in analog?
