Anyone have experience with building an 11-pin to Motionsound interface?
There's a great design by Bob Rinker I found online that is supposed to do everything I want, but it was originally designed for using with an XK3 and and older Motionsound Pro3.

(Bob are you out there?)

I have a Roland VK7 and a Motionsound Pro3tm/Low Pro stack (dont worry, I still love my C2 better)

Are there any signalling differences between the XK3's 11pin output and the VK7? Specifically, I'm concerned about the "sense" pin, and what voltage it takes for the VK7 to auto-detect the connection and disable the internal simulator.

Also, my pro3tm came with the newer style footswitch with the led indicators... I havent popped it open yet, but someone told me the slow-stop-fast signalling is wired differently than the older models... 
Anyway, my ultimate goal is to have the organ auto-detect the connection and disable the internal simulator, and have the slow/fast and brake buttons control the motionsound....

Any help would be much appreciated...
