New Audio Engine: Quick-Start Guide

Hi, I’m trying to build a basic system to animate the mouth of my characters using the envelope follower.

If I just have one character in a scene it works well, but if I have more than one then they all move their mouths together because they all use the same envelope follower preset.

Is there a way I can automatically create a new envelope follower for each character? There’s no limit to how many characters can be in a scene so all I can think of is to create a new one for each character like I am trying to do in this image, but it doesn’t work at all!
