30 * @brief SoundFont modulator functions and constants.
35 * Flags defining the polarity, mapping function and type of a modulator source.
36 * Compare with SoundFont 2.04 PDF section 8.2.
38 * Note: Bit values do not correspond to the SoundFont spec! Also note that
39 * #FLUID_MOD_GC and #FLUID_MOD_CC are in the flags field instead of the source field.
