null midi device

[Chris]

i'd like to contribute to the wine codebase and for some applications of
mine they request i have a midi device, but since i don't have one in
linux, wine doesn't show one either. i'd like to create a null midi
device in wine then, sort of like an optional midi device that appears
to the application to be a midi device and works fine but doesn't play
any music (so the application will at least run).

does anything like this already exist in wine, if not, how hard would
any of you experienced wine developers think it would be to create this?
where should i start?

thanks for any help you can offer.
