That SoundFont contains an ICMS INFO field which isn't defined in the
SF2 spec (contains the value "for Zimmer Museum by Morton Subotnick").
Regardless though, the spec says if any unknown INFO chunks are found,
they should be ignored.  Therefore FluidSynth should be fixed in this
regard.  The FluidSynth SF2 loader is based on older code from Smurf
SoundFont Editor.  Of note is that Swami does not have this issue in its
SF loader.  Will fix, thanks for reporting this.  Cheers!
