I'm not too sure what I'd call it. Thiago
Teixeira called it ttymidi:

Should do exactly what your looking for I think. Just
run his program, and any USB/Serial > device
can send data to ALSA MIDI. :-)

PS: Might be nice to send the author a
"thanks" if you like it
Thanks for make me remember ttymidi. I tried it and is perfect for the purpose to connect
arduino to fluidsynth.
Returning to the problem..., I imagine something like plugging arduino and appearing
automatically in aconnect. Maybe the solution is to hack the FTDI driver. FTDI is the
chipset that converts serial to USB, and needs an FTDI driver to create a virtual COM
port: /dev/ttyUSB0. The solution could be hacking the FTDI driver with the ALSA libraries
driver and making it an ALSA sequencer port.
