I've recreated (and tested) the macro - took me 5 minutes. Just out of curiosity, will it work for any of you? Does anyone want to try it?
Here we go:
1. Save the text below (between <?xml and </Macro>) as a plain text file. Name it "Default Channel Strip.studioonemacro".
You can also download it from this message.
2. Copy that file to your user 'macro' folder (check the location of the 'Macros' folder in Studio Pro 'Options/Locations/User data').
3. Restart Studio Pro.
4. Open Keyboard Shortcuts, search for 'Default Channel Strip' and give it a shortcut of your liking.
Please report here how it worked for you
