I really want to open my theorytabs in hookpad but i dont know how or if it is even possible.
All you need to do is to go onto the song’s Theorytab page, choose the section you want to open, and then click “Copy this TheoryTab into Hookpad”.
If you want to edit the tab, just click “Edit”. Although currently, you’re limited to the Flash-based Hookpad 1, instead of the HTML5 Hookpad 2 for now. I’m expecting the devs to eventually convert the database to Hookpad 2.
