I have an Alesis QX49 USB MIDI keyboard, jack midi is the only thing I
can get to work with USB MIDI.

I use audio/qjackctl to make the connections.

I use audio/jack_umidi to start a jack midi client so the keyboard
shows in the available jack ports -
jack_umidi -C /dev/umidi0.0 -B

and I have a patch for lmms that adds jack midi support

audio/hydrogen works with jack midi.

audio/zynaddsubfx can be built with jack support - start it with
zynaddsubfx -I jack
