Thanks to Christopher Arndt, I appear to have made a functioning fork:
https://github.com/ponderworthy/mididings
I'm not positive I have the namespace altogether consistent -- some of
the instances of 'Callable' are within a renamed collection, so I had to
rename the rename, in two files under 'units'; but it does seem to
work. Wiser Python heads may want to correct the error of my ways if I
miswrote!
Also, interestingly enough, there are apparently 37 forks of mididings
right now :-) I forked mine off the latest to date. Happy to see that
community.
J.E.B.
