Notice: Its using the coreaudio driver, not Jack. You probably need to run FluidSynth with "-a jack", note that the jack audio server needs to
be running. It would be interesting though to get your input about what it sounds like with the coreaudio driver. Last I tried it, it sounded
very bad (lots of static, even after turning the FluidSynth gain way down).

With the following settings:

I'm happy to say that the audio is crystal clear with both jack and coreaudio.

% fluidsynth -a jack

If there is some way I could save these events as audiofiles, I'd be glad to send them to you.

Best Regards.
