Also, when I save the XML and reopen the path has changed and no audio is passed via the wet path ?
I set it again , test , works , export ,open in daw and no signal ?

All very strange.

Here is my layout.
This is the main routing on top.

Then the wet and dry split.

This is then the output routing that works when testing but not on export.

And this is what it looks like when I close and open the project .
The routing has changed ? And this is probably the routing that gets exported ?

Am I doing anything wrong and btw , what is the difference between a grey and blue connection , cannot find anything in the manual.
