\page CreatingSettings Creating and changing the settings
|
|
|
|
Before you can use the synthesizer, you have to create a settings object. The
|
|
settings objects is used by many components of the FluidSynth library. It gives
|
|
a unified API to set the parameters of the audio drivers, the midi drivers, the
|
|
synthesizer, and so forth. A number of default settings are defined by the
|
|
current implementation.
|
|
|
|
All settings have a name that follows the "dotted-name" notation. For example,
|
|
\setting{synth_polyphony} refers to the number of voices (polyphony) allocated
|
|
by the synthesizer. The settings also have a type. There are currently three
|
|
types: strings, numbers (double floats), and integers. You can change the
|
|
values of a setting using the fluid_settings_setstr(), fluid_settings_setnum(),
|
|
and fluid_settings_setint() functions. For example:
|
|
|
|
\code
|
|
#include <fluidsynth.h>
|
|
|
|
int main(int argc, char** argv)
|
|
{
|
|
fluid_settings_t* settings = new_fluid_settings();
|
|
fluid_settings_setint(settings, "synth.polyphony", 128);
|
|
/* ... */
|
|
delete_fluid_settings(settings);
|
|
return 0;
|
|
}
|
|
\endcode
|
|
|
|
The API contains the functions to query the type, the current value, the
|
|
default value, the range and the "hints" of a setting. The range is the minimum
|
|
and maximum value of the setting. The hints gives additional information about
|
|
a setting. For example, whether a string represents a filename. Or whether a
|
|
number should be interpreted on a logarithmic scale. Check the settings.h
|
|
API documentation for a description of all functions.
