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