There is no direct connection from the control panel to the voice board. The knob scanner multiplexes everything into one serial stream and then demultiplexes this on the KLM-367 to the individual control voltages. Since the timing of the mux/demux is all controlled by the data lines on the KLM-367, nothing is going to work. Same thing with the lights on the patch buttons. A new or repaired KLM-367 would fix most if not all of these problems. Please don’t mention the trash bin. Fix it or sell it

Subject: [PolySix] Super wasted P6[Non-text portions of this message have been removed]
Hello group
First off, I must say this is a great group. Very alive, and lot's of skilled people. Great to see people taking care of this dear old synth.
I have a fully working P6. But the other day I helped a friend mine to remove the battery and acid to prevent his P6 from becoming more wasted.
Almost nothing is on his synth works. There is sound, you can play the keyboard, but it sounds like a broken toy piano. All the preset buttons are constantly lit, none of the knobs do anything. The arpeggio is actually working.
So I have 2 questions:
Could all this be because of the damaged KLM-367 board? I mean ok, that you cannot save patches, but this total superweirdness, is it only due to this board? Would a new/fixed board likely fix all the problems?
Can you bypass the KLM-367? If you don't want to save patches, and can live without effects? As an alterntive to either spending time and money on repairs or to put it in the trash bin. Or is it central to the functionality?
Regards
Fredrik
