No, -Xalsarawmidi does reduce MIDI jitter, but requires a2jmidid for the
routing. If needed I run

  jackd --sync -Xalsarawmidi -dalsa -r48000 -p256

and

  a2jmidid -e

$ man a2jmidid | grep -A2 OPTIONS
OPTIONS
       -e | --export-hw
              forces a2jmidid to bridge hardware ports as well as software ports

As already pointed out, newer versions of jack 1 provide an option that
also reduces MIDI jitter and a2jmidid isn't needed, but I didn't use it.
