I'm using _REGGAS2.STY. It seems as though when I do the Volume Automation, it moves the initial guitar strum right up to wherever I've "zero'd" the volume. Inherent in the RT? How odd...
Listening to your video again, are you talking about the ghost of a note immediately when the video starts - so right at the very first beat of the count-in?
If so, are you using any plugins in your mixer - particularly anything with a reverb?
If so, bypass the plugin and see if the ghost note happens.
