Discussion about the Korg PolySix synthesizer

I think i have another problem here, not related with battery leak, 
i just uploaded some photos , not very good quality, but the battery 
seems to be sealed, and the programmer is working despite some press 
memory recall buttons need cleaning or replacing. Well , the synth 
sound has some distortion and sounds like ring modulation, this is 
minimized if the negative/positive VCF EG Intensity is full 
clockwise. The preset sounds are like no envelope sustain , just a 
short low (frequency) click...well, i'm not a keyboard technician ,  
just trying to make something here, otherwise i will have to take 
the synth and schematics to a friend who is a technician (works in 
musical instruments, not vintage ones but...) and try to put this 
synth to play...have to say the brass and strings sections are ok,  
the split keyboard function switches and behavior are ok, bend and 
mod ok...well...lets see
