Hello Mattfig,
I made some tests and it appears that "safari" want to save our "tur" file as "html" file. You could either download them with "firefox" or change the file extension to "tur".
To change the file extension, select the file in your finder, click on "more info" and and delete ".html" from the box "Name & extension"
The "tur" file is our response format made with either "Torpedo Capture" or "Torpedo BlenderIR", they are specific to one setup (one cab, one mic). You have access to the overload parameter but you can't move the mic.
The "tsr" file is our factory response format made in our studio, they contains one cab and 8 mics. You have access to the overload parameter, the variphi parameter and you can move the mic.
