<p>Embeddable SoundFont synthesizer. </p>
<p>You create a new synthesizer with <a class="el" href="synth_8h.html#a344f7369c0f57d30f72702d0c88e6178" title="Create new FluidSynth instance.">new_fluid_synth()</a> and you destroy if with <a class="el" href="synth_8h.html#a585a63f3a25b9df17b82ae87f2d38cfc" title="Delete a FluidSynth instance.">delete_fluid_synth()</a>. Use the settings structure to specify the synthesizer characteristics.</p>
<p>You have to load a SoundFont in order to hear any sound. For that you use the <a class="el" href="synth_8h.html#aaf9376cf7189f9c64da5ffdeed85c9c4" title="Load a SoundFont file (filename is interpreted by SoundFont loaders).">fluid_synth_sfload()</a> function.</p>
<p>You can use the audio driver functions described below to open the audio device and create a background audio thread.</p>
<p>The API for sending MIDI events is probably what you expect: <a class="el" href="synth_8h.html#a4a98222fe1c36bfd598dc4cd89f4b75c" title="Send a note-on event to a FluidSynth object.">fluid_synth_noteon()</a>, <a class="el" href="synth_8h.html#a5e8f96cacbc6460f7677a6191cbd4472" title="Send a note-off event to a FluidSynth object.">fluid_synth_noteoff()</a>, ... </p>

Setting absolute to non-zero will cause the value to override any generator values set in the instruments played on the MIDI channel.
