Quad Osc (Re: exotic new modules ideas anyone?)

Hi Florian
Thanks for your response.
Your suggestions regarding a DCO or DSP based solution sound rather 
interesting ....
Well, I do not have a Nord modular myself, but besides the A-station, 
I have also used an analog Vermona Perfourmer 4-voice for this, but 
this has no PWM unfortunately. I do have four A-110's, an A-135 and 
the MCV24 so in principle I could go polyphonic with this as well, 
but somehow, I never came to do it.
I was came very close to an Rs370, but eventually I postponed it. 
A "digital" poly VCO from Doepfer in one form or another, as Shawn 
also suggested, would be really a must-buy for me.

best regards
Joost
