Dumb Question
What is the best way to restore back to the factory S4 mapping after having the DJTT custom S4 mapping installed? I don’t want to screw anything up. 
Thanks.
Select the small add button in controller manager in preferences and follow the steps to S4. Or run the setup wizard again to get everything back to default.
Yeah just restore the whole thing with setup wizard. If that doesn’t work, traktor comes with a backup!
