A somewhat related question: What is the currently
recommended way to
bridge between alsa and jack midi? For now I start jack with '-X
alsa_midi', which seems to work, at least in one direction.
I don't know. It might be different for jack1 and jack2 and for
different releases.
For a current project, just interrupted by a cold, the script to restore
sessions uses this combination, jack2 1.9.10-1 "-Xalsarawmidi" and
"a2jmidid", assumed it still should be the best solution to minimize
MIDI jitter, when using external synths, while for the few bars I played
until now, I don't use external synths. If this shouldn't satisfy me,
then I would start searching the LAU and LAD archives.
Btw. yet the project only uses synth plugins and the bridge isn't
needed:
