I've been fiddling around with the command line version of fluidsynth and I can't, for the life of me, figure out how to change the program.  I have the PC

yet I can't find any combination of the command 'prog' that changes to a different soundfont other than 'bright piano'.  Sucks, because there is a really good rhodes in here.. (which is also weird because it isn't in the list above.  Using fluidsynth-dssi, the rhodes patch shows up in program 4).

thanks if you can help,
