For all mechancial systems like the joy stick it's a problem to obtain the
same center position under all conditions. The reason is the balance between
the frictions forces and the spring forces which are different accorcing to
the way how the lever is released.

In the A-100 the adjustment of the max value is not necessary as for
(nearly) all CV inputs one has an attenuator that can be used to adjust the
effect of the voltage swing coming from the A-174. If you want simultaneous
control for both directions the A-132-2 Quad VCA may be used.

There are two jumpers on the A-174 pc board that are not yet mentioned in
the user's manual so far. If these are removed one obtains kind of a plateau
around the center position (one is for X, the other one for Y) that
compensates these differences. Maybe this helps to solve your problems.
