v1.17

• Fix FM algorithm 4 having operators 3 and 4 incorrectly defined as the output operators. The correct operators are 2 and 4. Changes to MIDI volume/velocity would have caused to the wrong total level parameters to be modified, resulting in an incorrect sound.
• Added "Ch3 Special/Normal" indicator to the UI for FM parameters to show the status of Ch. 3's Special Mode.
• The velocity of note on events for MIDI channels 11-13 is now applied to the respective operators of Ch. 3 when in Special Mode. The velocity is only applied to operators which are designated output operators according to the algorithm in use. This prevents velocity from fundamentally changing the sound, rather than just the volume.
