Patches and discussion for Ensoniq VFX family

Repairing the VXF SD1 that I had bought at a garage sale I was able to
get everything working on it, I ordered the Manual and OS disks. The
only thing that does not seem to be working is the mod wheel. I am
wondering if maybe I am just not using it right, but it doesn't seem
to do anything. I tried to use the manual to find out how and what I
can do with it and it doesn't seem to do anything. Can any one give me
something simple to try with it so I can at least see if it is even
working, I would appreciate any information on the use of the mod
wheel, thanks
