Eml synthesizers

Not a clue. I don't have a 500. But, the 400 filter uses that board. 
Look for a 15K resistor connected to the top of the Q slider.
 
That 15K resistor connects to the input of a 748 quad op amp, two 100K
resistors and a 3.3pF cap.
 
The 100K resistor in parallel with the 3.3pF cap is the feedback limiting
resistor from the LP output back to the network input.
 
Reduce the 100K.

Ressistance in the feed back path eh? Any hints what components that
resistor would be between?
