It just keeps saying “location does not contain project file” and will not let me load project from beatbuddy with card, SD card, or Downloaded file HELP!
You are using File > Import Project. It wants the .BBS file (like a project shortcut).
In order to import content from the pedal SD card (or downloaded content), you need to use Import - Export > Import Project from Pedal.
If you save the project afterwards (File > Save Project), the necessary .BBS shortcut will be created for you so you can switch between different project swiftly.
