Subject: some defects after battery leak

Hi, I am a new member. I live in Belgium and I am dutch speaking so maybe all my writing is not correct ;-(

I have a polysix that has always been mine. It also had the battery leaking problem. I managed to repair some broken circuit lines and I think they are all as they should be. ( checked with an OHM-meter all the connections for IC 31 ) Now most things work ( VCO, MG, VCA, EG and programming  ) but there seems to be an "interaction" between the various knobs. turning the VCF resonance knob  interferes with the EG or effect part and so on. turning the Keyboard tracking results in some strange noises... I mean :  various knobs don't behave as they should do and when I turn them to low or to high it results in changing the sound in a way that is not good ( the EG holds on even when all knobs of the EG are zero or when I turn the speed of the effects it results in a "faulty" noise).... Does anyone have an idea what could be the cause?
