I'm still fairly new, but I'd love to learn a way to mask anything (an audio spectrum in particular though) to the lines generated by Plexus, if possible.

When you say, "masking to lines", what do you mean? You can use the lines as a track matte, but do you mean more like matching motion?

Yes, I do mean more like tracking motion. I'd like an easier way to have an audio spectrum aligned with Plexus lines, other than manually editing each frame, or each couple of frames.

How are you generating those Plexus lines? Are they connecting two nulls together or...?

Currently two or more lights, but let's use two for now. I imagine I can mask to the space between them, but... You know, new and all. Don't know how. =/

Tie the end points of the effect to the position of the lights.
You'd need to use an expression to get a 2d point from a 3d position though.
Something like
thisComp.layer("Light 1").toComp([0,0,0])
(Make sure you change the name of the Light to whatever you've named your lights.)

If you want to do it for multiple lights, you'll need to use several copies of the Audio Spectrum effect and limit each effect to a particular segment of the audio frequency so that each piece eventually makes up the whole thing.

Doh! You're absolutely right. I was thinking about pathing, and I completely glossed over the start and end points! Thank you!
