For intercepting events from the midi player, use fluid_player_set_playback_callback() to register your custom processing function of type handle_midi_event_func_t.
For intercepting events from the midi driver (your keyboard), create the midi driver with new_fluid_midi_driver() and pass a processing function of type handle_midi_event_func_t as well. http://www.fluidsynth.org/api/index.html#RealtimeMIDI Once you're done processing events in your custom function, you should call fluid_synth_handle_midi_event() to pass the event on to the synth.
