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...
