wst25fstein.sf2
   Played successfully here via aplaymidi -> fluidsynth with wst25fstein.sf2 
(some Steinway knockoff), with a few crackles.
   Played first with the FluidGM percussive organ and it went into 'undead' 
mode after I killed the aplaymidi process.
   Just kept on looping unitl I killed fluidsynth.
