Great replies and thank you all.
It is complicated. What would one use that for? Any typical reason?
Like I said, I saw the guy on You tube use it to take away the delay “wet” signal while the actual guitar
signal was active. So the delay wet signal was only heard in between the notes. It kind of cleared it up and made his riffs less muddy. That was a good technique.
What else could you do with it? Especially in the example Strophoid mentioned?
What is the purpose of using another track to effect the comp on another track?
Thanks alot. I appreciate the patience with a Mega-Newb.
