That was my thinking as well.  The downside is that, to be on the safe 
side, it appears you should first issue a router_clear command and rebuild 
the 1:1 mapping from scratch, excluding CC7 (and CC39, as I believe main 
volume is a 14-bit controller).

At this point, you can either add a new CC7 rule or just "set it and 
forget it."

Fortunately, there's only note, cc, prog, pbend, cpress, and kpress, so 
it's not like it takes thousands of lines.  Still, it sure would be nice 
to be able to issue a command like "router_clear cc".

Generally speaking, that should *never* happen, however, AFAIK, the 
majority of "hardware" synths handle it by ignoring it. :)  On a linux 
system, I might bang out a quick-and-dirty filter to interpose between 
fluidsynth and the event source (the ALSA sequencer API makes this easy), 
but darned if I know what to do with windows.
