jack_capture constantly monitors which jack ports are connected to
the soundcard, so it will record everything you hear, even if fluidsynth 
makes the jack connection after it starts playing. After 
recorded, you can import the sound into ardour.
jack_capture can be downloaded here: http://www.notam02.no/arkiv/src/

As an alternative, I think you can use the patchbay in qjackctl as well to 
make sure fluidsynth always connects to ardour.
