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:

$ cat /home/music/arch2014.1/start.03.01

$sessiond/aj-snapwrap --killall
killall -9 -wq qjackctl qtractor zita-at1 jkmeter meterbridge a2jmidid jackd hdspmixer

# Restore session
roxterm --tab -n "♪ hdspmixer"   -e "hdspmixer"                                              ; sleep 2
