Need help on a show! How do I import fixuters into hog 4 from a usb stick

I suppose that you want to import a fixture profile made by highend.
Go into the file browser and drag and drop you file from your usb stick into the folder "library".

Then go to your patch window and in the schedule window you will find in the bottom a button called Library. When you push that button you can choose the file you have put into the folder.

Hopes this helps.

Thanks for your help!
