In addition to Kai's snd-virmidi trick, I would add that FluidSynth has
rawmidi support. So you can use the pipe directly, without ALSA at all. For
instance:

$ mkfifo $HOME/midipipe
$ fluidsynth -a oss -m oss -o midi.oss.device=$HOME/midipipe soundFont.sf2

MIDI Note On event typing this command in another Bash session:

$ echo -ne '\x90\x40\x7f' > $HOME/midipipe

P.D. You can download a new, fresh FluidSynth 1.0.9 release and enjoy!
