It appears that the ALSA audio device is set via the "audio.alsa.device"
settings parameter. So you could set this via the fluidsynth command
line like so:
fluidsynth -a alsa -o audio.alsa.device=hw:1

This would set the audio device to the second sound card I believe. I
think you probably still want to use the ALSA sequencer though "-m
alsa_seq". Once FluidSynth is using the ALSA sequencer you can connect
your MIDI device to FluidSynth via the acconnect utility. Do a "aconnect
-li" to list the input devices (your external MIDI port should be
listed) and then "aconnect -lo" to list output devices (FluidSynth
should be listed). Then you can connect the two ports with a command
like so:
aconnect 64:0 128:0

Which would connect port 64 and 128. I guess you could use the ALSA raw
MIDI driver in FluidSynth, but I don't really see a reason for that,
since the sequencer is so much more flexible. Hope that helps.
