So it is exponential? How did it track the keyboard then? Or didn't it?
Where was the keyboard signal applied? Via one of the mod inputs? But in that case the pot would affect the tracking.
Did the MS-20 keyboard output an 1 V/oct signal or some V/Hz signal? Maybe it had a 1 V/oct signal for the filter and such, and a V/Hz signal for the VCOs?
