Bryan,
The problem happens when you try and encapsulate a callback routine into a
c++ class as the this pointer is undefined at compile time with respect to
the win32 SDK. This issue happens because win32 was written in straight C.
There are a number of possible ways around the issue - the best is probably
to use a pseudo this pointer declared as a structure, as this method is
thread-safe, which will be a requirement for my code. I've found a good
article at http://www.ddj.com/cpp/184403375 which describes the issue and
possible remedies. I'm sure I could crack this myself, but it'll be faster
to get somebody else to do it who has more experience. An additional
problem is that I can't just release a copy of the code without an NDA being
in place, as it contains a definition of the Mackie protocol which I had to
sign an NDA to get, though I can distribute it to any nominated contractor
who also signs a copy of the agreement.
Best wishes.

Tim, what is the issue? I might not be able to solve it personally, but I
can probably find you an answer.

Chris,
They break easily, but the next option for better quality would be a Mackie
Control Universal and you may have to remortgage to afford one. I'm still
working on my Mackie Display Reader project, but that should work with any
Mackie-compliant surface - the project is somewhat hung at the moment due to
an incompatibility between c++ code and the Win32 SDK, but I'm trying to
find a programmer with enough experience to overcome the issue and I'll pay
him to do it quick rather than keep the project stalled.
Best wishes.

So, a fair number of blind people are using the Behringer BCF2000 control
surface?
I'm impressed that a surface that cheap has motorized faders!
Any caveats before I go pick one up?
thanks
Chris
