I think it does default to bank 0 preset 0 on all channels.  The issue  
is actually with the fluid_synth_sfload() call in the example code.   
The 3rd parameter is called reset_presets.  If its FALSE then no  
instrument changes are made on any MIDI channels.  If TRUE then all  
MIDI channels are refreshed (as if they had bank/program change  
messages sent) which may cause new instruments to get used from the  
loaded SoundFont.  Perhaps the example should just be changed to pass  
TRUE as the 3rd parameter.
