There is a function that returns this as a string. It needs to be  
assigned earlier than it is. Fluidsynths settings are not ready until  
fluidsynth has initiated so the fnction is returning NULL. Perhaps we  
wait until the synth starts then launch a function that checks to see  
if the Denemo.prefs variable is NULL or empty string. If so then  
assign the default the returned string from the api reference call.  
This will take little modifaction to do.

I will do this.
