Portal 2 Dynamic Music without scripts

This is a project I've been working on for a couple of weeks and like to know what your thinking. It's a func_instance where you have more control over an ambient_generic.
Here is a link to the vmf-Files:

I would appreciate a message if you finally use it in one of your maps. =)
The main-features:
- working fadeIn
- working fadeOut
- mute (but play further)
- repeating without cue-points
- mix many of them with different volumes (turret-case)

So that's how they made the singing companion cube.

[@andrev.1721]

The turret said: "Suche!" in german which is english for "search".

Hey! Sorry, but ThinkingWithPortals domain is no longer available, so it's impossible to download the files. Do you still have them? 👉👈

Do you have this uploaded on the new ThinkingWithPortals website? I have the same issue with the link currently provided as another peep in comments does with it redirecting to a sketchy site.
