wait wait!
actually I got wrong! ..
I'm still missing a part
of course a child track sends it's out to the folder track..
but I wanted to do the opposite..
I wanted to have a ghost track of the Folder's out to be treated seperately
now...this is not possible. it just have to stay outside the folder and be an individual track..
so the missing part is:
why the folder's output cannot be sent to one of its (empty) child tracks?
maybe has something to do with their father-child relationship?
a folder/father track cannot send its output to one of its children tracks?
I would like to figure out why exactly for a deeper routing understanding
