Subject: Re: Modwheel VCO VCF VCA Issue

From: "djangowes" <djangowes@yahoo.fr>

Ok. after some searches, I'm pretty sure it comes from the KLM367. My P6 had a battery leak then has been repaired before I have it.
I'd like to know where is produced the LFO signal. (what part of the circuit). Then the idea would be to follow the signal and find the place (crossroads) where it has to choose between VCO, VCA or VCF.
Anybody knows?

thanks,
