Has anyone attempted this?  If so, can you send me your brain?  I've used the better part of a vacation day on it, and I don't have anything to show for it.  BTW, I'm not using ModIO since I have enough inputs on my parallel port to do the job.

Here is a plugin I wrote a while back that does EXACTLY what your talking about.......
the are instructions in the thread about it.......  It can do 6 axis and 4 axis and you can use axis 5,6 for SSO and FSO
