It seems like doc/example.sf2 is ripped from VintageWavesDreams-v2.sf2. This makes this problem worse since 1) This is not allowed according to VintageWavesDreams-v2.sf2's license 2) doc/example.sf2 is distributed as a part of the binary package libfluidsynth-dev Reference: http://lists.gnu.org/archive/html/fluid-dev/2009-04/msg00081.html
