ODP: Design your own DW8000 synths?

[Roman Sowa]

I did that in my Poly (DCO->VCA->VCF) and it is noisy like hell (8 voices).
CV bleedthru rumbles all the time, at high Q inharmonic coloured noise
is slowly rising due to leaking VCF's S/Hs.
I would never do that again, especially with CA3080 in VCF.
But besides that it is very nice architecture. With short release time
and high Q filter it is something really different.
