Thanks to Christopher Arndt, I appear to have made a functioning fork:
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.
Mididings may be the only JACK-api MIDI router/filter tool around; if there is another I'd love to know about it. On the other hand t was working just dandy until, I think, some changes to both Python3 and legacy support for Python2. I was using its Python3 AUR adaptation (mididings-git) under Manjaro, but then after package upgrades, it began to fail at 'from mididings import *' (see below). I found similar failures in Ubuntu 20, and found different failures in both when I tried setting up to use Python2 (which obviously we would rather not be doing). The failure is similar to a number of failures reported starting with Python 3.10, so this may be related, but I was not able to figure out how to apply those workarounds to the mididings source, I tried several different variations, including a number of the different forks in github.
Thoughts, anyone? I found Pigiron and Jamrouter and puredata, but none of these appear to do JACK. I'm using pipewire now, so I could theoretically revise the whole rig around ALSA MIDI, but all of the apps needing MIDI use JACK, and mididings is so elegant...
