Awesome.

Are you sure it isn't /dev/rmidi1?
The last line in your dmesg output indicates it has attaches as midi1.

LMMS takes a raw midi device but midirecord uses the sequencer.

The code "looks like it should work". Sadly, I haven't had an opportunity
to test LMMS with a real MIDI keyboard - I use a computer keyboard.
The code and support in fluidsynth is very similar.
