That's it. However, there's no need to set "audio.driver" since the
audio driver code has been moved out of the synthesizer object.
The settings that you may be interested in are (with their default
values):

synth.midi-channels      16
synth.polyphony          256
synth.sample-rate        44100.000000
synth.gain               0.200000
synth.chorus.active      yes
synth.reverb.active      yes
synth.ladspa.active      no

You can get rid of readline support at compile time:

  ./configure --with-readline=no

I took a quick look and it looks good to me. Just one thing,
FluidSynth can handle sampling rates != 44100 without being out
of tune. Only the reverb may sound a bit different.

Drop a line when fluid~ is running so we can add a note about
it on the FluidSynth web site.
