Dick, what is the model number of the Hammond module that you are using? Will look up the manual to see if I can help. It should be a rather simple setup. Page 190 of your KN7000 manual tells you how to set up midi channels so that you select the appropriate notes to send to the sound module.

Also tell me what notes you want to send to the Hammond module. I assume you would want your right hand notes to cause the Hammond sounds, but not sure.
