  31  *
  32  * This header defines useful functions for programatically manipulating the ladspa
  33  * effects unit of the synth that can be retrieved via fluid_synth_get_ladspa_fx().
  34  *
  35  * Using any of those functions requires fluidsynth to be compiled with ladspa support.
  36  * Else all of those functions are useless dummies.
