I have here a CS-60, which I have to tune after a minor repair.

I could set the absolute tuning and the octave tracking fine in the 
upper octave setting. But tuning all the lower octave switch settings is 

Can some of you judge, whether there is a real need to do this on the 
boards itself (e.g variation of the VCO ICs), or could I move the 
trimming to a central voltage provided by the switches?

(Yes, I have understood that at the moment the switches send only a 
gate, which enables the corresponding trimmer - I think about replacing 
this complete section on the M boards)
