1. In case you don't know, you don't have to use JACK MIDI
   if you don't want to.  Most JACK Audio apps work just fine
   using ALSA for midi.

2. Instead of a2jmidi, have you tried:

      $ jackd -d alsa -Xseq

   This is the built-in ALSA-to-JACK midi bridge.

3. Don't connect anything on the ALSA page of QJackCtl.
   Just make your connections on the MIDI page.

Sync Mode doesn't matter unless there are other programs you want to sync.
with.  I'm not sure about the others... probably *not* GM.  (For example,
a GM Drumkit alway transmits on channel 10... but what if your SR-16 is
configured to channel 1?)

Place note:  In the grid area click and hold your RMB.  With the RMB held
down click your LMB.  seq24 comes with a README, and I think that this
(and other stuff) is in there... but you have to read slow.

Another choice:  The Non Sequencer (http://non-sequencer.tuxfamily.org/)
is very much like seq24 and uses JACK MIDI.
