Usage:
fluidsynth [options] [soundfonts] [midifiles]

If we use the old one,we will see:

Parameter '-F' not a SoundFont or MIDI file or error occurred identifying it.
Parameter 'output.wav' not a SoundFont or MIDI file or error occurred identifying it.
Parameter '-r' not a SoundFont or MIDI file or error occurred identifying it.
Parameter '44100' not a SoundFont or MIDI file or error occurred identifying it.

Now, [options] are on the front
Use "fluidsynth -ni -F output.wav -r 44100 sound_font.sf2 input.mid"
