I have been trying to get the voice and effects down for Jedi Master Plo Koon for a while. I have scoured the web for a tutorial but came up empty. Instead, I have had to play with my own voice while recording and then just play with settings in post to get it close to the sound I want. It's not quite perfect, but some of the sounds hit pretty close to the mark. I will have to keep working but I think I am making pretty good progress!
