How to merge values in order to create a new waveshape?

Hello vvvv folks!
I’m trying to make a kind of advanced animation waveshaper. The goal is to merge values in order to create new shapes of animation and being able to make my animation match to a music rythm.
A picture worth more than words, please look at the .jpg file.

The green line show the result i’m trying to obtain.
The bottom right shape is the result of a basic addition of the values.

In Illustrator i would use the pathfinder tool to merge both shape, in a 3d software I would use a boolean operation ADD. I don’t find anything in vvvv to do it. Please help.
Thanks !

for me it looks like you want to take the higher value

I think the node you are looking for is Max (value).
And you can use Herr inspector to increase the input count to mix even more waves.

Wonderful! thanks Phlegma and Westbam.
