CC commands in Voiceworks How to

I am looking through the manuals and trying to figure out how to send a CC command from my sequencer to automatically turn the harmonies on and off at specific location. It seems that each voice has a command do I have to send each everytime i turn on or off, or is there a global command that will turn the harmony at once? Also i gather this requires the system be set to advanced?

Also can a command be sent to change the harmony patches, and or settings as well?

Lastly, is there a full list of the CC commands that is more intuitive than the implimentation list in the manual, and or a better detailed explaination of how to do this process.
