Re: Quick question: DCO1 > DCO2 FM, DCO > VCA AM, DCO > Reso 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  
http://f1.grp.yahoofs.com/v1/wBPFSGq0g4xwVsPrD-
tiY5k2Xonbsh3nTwrbSw63eKe9kquZ4fErzWXb1oBZAbSAuql8UjCDeoRAAj3oY5qZYPW6
fEslAeJMHz4/Technical/Poly800%20-%20Matrix.jpg  . Sorry for quality - 
it is scan of my hand-drawed night mares...)
