Yo,

Check out:
http://theatreorgans.com/hammond/drawbar.htm
http://theatreorgans.com/hammond/paul.htm

Not quite what you wanted, but does have info on
drawbar operation. The drawbars are in effect a
Fourier Synthesis tool. Each drawbar adds a sine wave
and thus represents a spectral line. The amount the
drawbar is pulled out cooresponds to the amplitude of
the spectral line.
