Discussion about the Korg PolySix synthesizer

Thanks for your interest.
I own a oscilloscope. Im a technician but have never worked on synths.
I have downloaded the service manual but im not too clear on how the circuit operates. I know enough to get around on the board and do some testing. 
I agree the fault must be on 366 board and it must be related to a component/s that shares the last 2 voices
Any pointers will be very much appreciated.
thankyou
