For reference. The units in fluid_player_set_bpm() are beats per minute. In  
fluid_player_set_midi_tempo() the argument is given in microseconds per beat. 
The default values are BPM = 125, MIDI tempo = 480000. There may be a bug in 
the last function, where it calculates the deltatime value in milliseconds 
per tick, using the player->division value assigned from the loaded SMF 
header (division field). Can you compile FluidSynth in debug mode, and take a 
look to the log output?

As David said, you've found several unimplemented and/or broken functions. 
Please, can you create tickets into the bug tracker?
