* Set a SoundFont generator (effect) value on a MIDI channel in real-time.
* @param synth FluidSynth instance
* @param chan MIDI channel number (0 to MIDI channel count - 1)
* @param param SoundFont generator ID (#fluid_gen_type)
* @param value Offset generator value to assign to the MIDI channel
* @param value Offset or absolute generator value to assign to the MIDI channel
* @param absolute FALSE to assign a relative value, TRUE to assign an absolute value
* @param normalized FALSE if value is specified in the native units of the generator,
* TRUE to take the value as a 0.0-1.0 range and apply it to the valid
* generator effect range (scaled and shifted as necessary).
* @return FLUID_OK on success, FLUID_FAILED otherwise
* @since @NEXT_RELEASE@
*
* Parameter numbers and ranges are described in the SoundFont 2.01
* specification PDF, paragraph 8.1.3, page 48. See #fluid_gen_type.
* This function allows for setting all effect parameters in real time on a
* MIDI channel. Setting absolute to non-zero will cause the value to override
* any generator values set in the instruments played on the MIDI channel.
* See SoundFont 2.01 spec, paragraph 8.1.3, page 48 for details on SoundFont
* generator parameters and valid ranges.
*
* @note The old behaviour of fluid_synth_set_gen() assumed \c absolute and \c normalized to
* be FALSE.
