I'm not sure mididings is the right tool for the job. The Python code to
transform the events would be quite simple, but mididings doesn't support
reading/writing MIDI files (yet?). You could of course use a separate MIDI
player/recorder, and route the events through mididings, but you'd lose all
meta information (tempo, time signature, etc.) from the original file.

Having said that, I don't really know a better solution.
midish (http://caoua.org/midish/) can import/export MIDI files, but I'm not
sure how/if it can do the transformation you want.

As far as I can see, all tracks in your MIDI file are on the same channel,
so CC #7 messages on one track will affect the other tracks as well. You
should probably assign a different channel to each track.
