Non-iteratively getting the list of instruments in a soundfont using FluidSynth

Question

Is there a function that can return the list of all the instruments (preset names) in a soundfont file in FluidSynth or at least the number of presets in each soundbank?

Answer 1

This is not exactly "non-iterative", but it's the only way I could find to get a list of all the presets in a soundfont file.

fluid_preset_t* preset = new fluid_preset_t();

// Reset the iteration
sf->iteration_start(sf);

// Go through all the presets within the soundfont
int more = 1;
while (more) {
    more = sf->iteration_next(sf, preset); // Will return 0 if no more soundfonts left
    if (more) {
        // Get preset name
        char* presetname = preset->get_name(preset);
        int banknum = preset->get_banknum(preset);
        int num = preset->get_num(preset);

        // Do something with the presetname, bank number and program number
        // Such as add it to some list so that you can refer to it later
    }
}

... where sf is a soundfont object.

Found this while going through the API documentation at http://fluidsynth.sourceforge.net/api/index.html. Note the menu at the top with links to the data structures, files, etc.
