The good news is that they are CC#80 for the upper manual, and CC#81 for the lower manual.

The bad news is that they are CC#80 for the upper manual -- all nine drawbars! -- and CC#81 for the lower manual. Ham-Suz did a very strange thing, probably to minimize the number of CC#'s they used"

16' @ "0" --> CC#80 = 0
16' @ "1" --> CC#80 = 1
...
16' @ "7" --> CC#80 = 7
16' @ "8" --> CC#80 = 8

5 1/3' @ 0 --> CC#80 = 9
5 1/3' @ 1 --> CC#80 = 10
etc.

This 'works' because 9 drawbars x 9 settings = 81 data points, which is within the range of a MIDI CC# (0-127). It also renders the XB/XK incompatible with the Voce Drawbar Module or any other MIDI controller that an owner might want to use. It's possible to do some sort of mapping between devices, but I don't know of any off-the-shelf MIDI adapter that will do the trick (including MIDI Solutions' gear). :^(
