+	  FluidSynth is a real-time software synthesizer based on the
+	  SoundFont 2 specifications and has reached widespread
+	  distribution. FluidSynth itself does not have a graphical
+	  user interface, but due to its powerful API several
+	  applications utilize it and it has even found its way onto
+	  embedded systems and is used in some mobile apps.
