Here's another link you may have seen about synthesizing the Hammond:

http://www.electricdruid.net/index.php?page=info.hammond

One thing I understand the clones do that helps create a realistic imitation is "spin" all the 91 or 96 virtual tonewheels in lock-step like they are in the mechanical generator. You can't tell the difference with individual notes but playing chords will reveal whether your playing from samples or a clone.

Cheers,
Rock
