Discussion about the Korg PolySix synthesizer

Please explain to me how the Opto thingamajig is supposed to be
connected, all it says in the Files section is what resistor to
change. It doesn't explain to a moron how the vtl5c3 is connected,
like I said before it has 4 connectors, and the old part has 5 (or 6,
i'm confused)
What connector goes where?
I don't know much about this but I know that I want the F***er to work
properly.

And I would like to apologize for my temper, and aska again, does any
one have any idea why my polysix arpeggiator slows down when i fiddle
with the adsr and EG settings???

There I said it, sorry but it appears I'm a moron...
