If all the sliders on the panel operate only in the top half of the
mechanical range, then there may be something electrically broken on the
panel, and calibration won't fix it. Are you sure this is the case? For
instance, does the sweep rate control do nothing until it is at least half
way up? The same for filter cutoff? Envelope attack time?

It could be a bad A/D converter chip (Z53), or something in that circuit.

The lever assembly is the thing with the two levers to the left of the
keyboard. If they work properly, with the proper ranges, then you don't need
to do the lever assembly voltage adjustment.
