Thanks for trying it out, I was just thinking today about how I'd like
to hear more reports of how FluidSynth is working on OS X. I've
experienced some problems myself, so I want to see if others have the
same experience.

I think you will probably need to get MidiShare
(http://www.frame.fr/MidiShare/). Its the only MIDI driver I think that
will run on OS X that FluidSynth supports (Markus, Peter, or anyone else
please correct me if I'm wrong). I'm not really familiar with the OS X
platform, so I don't know what its native MIDI interface is. As things
are you can probably test the synth with a command like
"noteon 0 60 127" which will play note 60 on channel 0 at 127 velocity
(highest). For the Vintage SoundFont the note will stop itself (first
preset is not continuous), for continuous sounds you'll need to do a
"noteoff 0 60 127". You can perform this test without having a MIDI
driver.

Now to the problem that I have had. I've experienced rather noisy output
from FluidSynth, like a lot of static. I've tried increasing buffer
sizes and counts (-z and -c, do "fluidsynth -h" for command line help),
but this didn't seem to help. Let me know if you think the output is
noisy as well. I want to try and track down whats causing that.

I'd like to have Mac OS X binaries available, but I need to research how
this is done on OS X. I also need to sort out what MIDI driver gets
compiled, which you are helping with :) Cheers.
