I just fixed the ability to change the default volume to staffs in git.
The lowest volume allowed is and 1. I have not looked into why. We would
need a separate mute button anyway because export midi would still sound
it if it had volume 0 and someone placed a "f" or forte on that note. 

If you want to play around with this stuff I would say go for it. Having
looked at staffpropdialog.c I realized how much of a mess it is in. I
really like what Richard was doing with the #define macros in
prefdialog.c. If you want to rewrite some of staffpropdialog.c to make
it model what Richard was doing in prefdialog.c with the macros. This
would be a good entry point for you for doing what you mentioned. All
the data structures that you will need to know are in the
include/denemo/*.h. 
exportmidi.c controls the midi output.
