The latest release (1.0.7a) has some major bugs which made it unusable for me, so I had to use a CVS snapshot.

<code>
cvs -z3 -d:pserver:anonymous@cvs.savannah.nongnu.org:/sources/fluid co fluidsynth
cd fluidsynth
sh autogen.sh
./configure --prefix=/usr
make
</code>

<code>
make install
</code>


Asking FluidSynth to become an ALSA sequencer (using SoundFonts):
<code>
fluidsynth -m alsa_seq /path/to/8mbgmsfx.sf2
</code>
