I have a degree in maths, and I studied electronic engineering for a while.  I also own more synthesizers than I probably should - so I understand the concepts involved.

What I mean is, the response curve of this one, for gain vs CV, is far from desirable.  I get a very gradual increase, then a very sudden one.  I haven't attempted to graph it.

I have seen that website page before, and read the manual, but I haven't seen anything official about adjusting or calibrating one.  I have read that there are preset pots to adjust, but only vague details.

It seems the one I have is version 3, and there are only two presets / trim pots, labelled Gain Offset, and Output Offset.  Is there anything to be gained by adjusting those

I own multimeters, basic oscilloscopes, soldering irons, and a large heap of resistors, capacitors and various other components.  I am quite prepared to modify it, if necessary.  Is there a schematic available
