I am thinking that it may be a bad track or something similar around the key assigner circuit somewhere, but I was wondering if anyone could help with where exactly I should be looking.The symptoms are - in poly or unison modes I can only get voice 0 to sound. All the voice LEDs cycle as normal, however only voice 0 actually has output.I then found that when I pressed on the board around the key assigner/CPU area on klm366 all voices could be heard and triggered successfully. This is an intermittent connection of some sort surely, but I'm having trouble locating it. I have verified continuity along the data lines and they all seem good. The board does have some minor trace repair already, on IC3 from memory. But it has never had a battery fail issue.It seems really strange that the LEDs light, which would indicate gate signal is present (?) but then the voices don't sound. Perhaps this points towards something between the envelope and the filter? Anyway any input from you wise people would be much appreciated. I'm not familiar enough yet with the polysix circuits to know what may be happening.Thanks a lotLuke
