I had that issue with my MS-10 and the tech found that the cable from the keyboard to the VCO pitch was broken. He replaced it and everything worked fine again.
I suspect the cable is fine but that's easy to check, and a longer cable would be really nice
Noise sources, modulation, filters and EGs are fine. I actually get sound from the top couple of keys (just way too low frequency) and everything from mixing the VCO's through the rest of the synth is working as expected.
