The poly800 schematics can be found in the file section of the group.  
If you check the "poly800text.txt" circuit description, it says the 
filter and VCA part of the circuitry is circuit 27, which I think is on 
p800_2.gif.
There was talk about this a while ago, but I can't remember what the 
recommended method was.  But I'm fairly sure it was fairly 
straight-forward.  Maybe it'll be somewhere in the archives?
Sorry I can' be of more help at the moment, may get around to searching 
the archives and see what I can find
