SoundFont synthesizer
You create a new synthesizer with new_fluid_synth() and you destroy it with delete_fluid_synth(). Use the fluid_settings_t structure to specify the synthesizer characteristics.
You have to load a SoundFont in order to hear any sound. For that you use the fluid_synth_sfload() function.
You can use the audio driver functions to open the audio device and create a background audio thread.
The API for sending MIDI events is probably what you expect: fluid_synth_noteon(), fluid_synth_noteoff(), ...
◆ delete_fluid_synth()
◆ fluid_synth_error()
Get a textual representation of the last error.
- Parameters
-
- Returns
- Pointer to string of last error message. Valid until the same calling thread calls another FluidSynth function which fails. String is internal and should not be modified or freed.
- Deprecated
- This function is not thread-safe and does not work with multiple synths. It has been deprecated. It may return "" in a future release and will eventually be removed.
◆ fluid_synth_get_cpu_load()
Get the synth CPU load value.
- Parameters
-
- Returns
- Estimated CPU load value in percent (0-100)
◆ new_fluid_synth()
Create new FluidSynth instance.
- Parameters
-
settings | Configuration parameters to use (used directly). |
- Returns
- New FluidSynth instance or NULL on error
- Note
- The
settings
parameter is used directly, but the synth does not take ownership of it. Hence, the caller is responsible for freeing it, when no longer needed. Further note that you may modify FluidSettings of the settings
instance. However, only those FluidSettings marked as 'realtime' will affect the synth immediately. See the fluidsettings for more details.
- Warning
- The
settings
object should only be used by a single synth at a time. I.e. creating multiple synth instances with a single settings
object causes undefined behavior. Once the "single synth" has been deleted, you may use the settings
object again for another synth.
- Examples
- example.c, fluidsynth_arpeggio.c, fluidsynth_fx.c, fluidsynth_metronome.c, fluidsynth_register_adriver.c, fluidsynth_sfload_mem.c, and fluidsynth_simple.c.
