Korg Mono/Poly

Thanks for the reply Florian - I am wondering where to measure on the 
low/mid/high switch, there are eight points - do I just choose any 
one of the four pairs and do them across? 

I'm confused on how to measure the VCA out and VCF out testpoints, 
would I be looking for some kind of voltage reading, or is that for 
placing the output to an amp like an audio cable to test for sound?

Thanks again for your help, I will have a chance to test some things 
out when I get out of work in around five hours.
