Subject: Re: Quick question: DCO1 > DCO2 FM

Hi,
hopefully, I will soon post my "semi-modular" like modifications,
where several modulations will be possible.
Until now from my Poly800 I´ve heard DCO->Chorus, Chorus LFO->VCF
Resonance, ChorusLFO speed changing is easy as well.
But poor old Poly800, with wires sticking out around. I had to
assembly it back together...
Now I uploaded block-diagram for Poly800 with possible inputs/outputs
at least - in the Files > Technical section

fEslAeJMHz4/Technical/Poly800%20-%20Matrix.jpg . Sorry for quality -
it is scan of my hand-drawed night mares...)
