I'm CC'ing the FluidSynth developers list since this is a good thread to
continue discussion on. I myself have not given the OS X version a try
(beyond some of the work I was doing last year).
Its nice to hear that OS X has Jack support. This sounds like the best
option, since the native CoreAudio driver has had some problems. What
does the link command look like during the build? Does it have -ljack,
or something similar? Make sure the Jack library is being linked in at
the last stage. It would be nice to provide a package of FluidSynth for
OS X eventually, to make things nice and convenient. Regards,
