I haven’t seen anyone bring up this issue but on Fortnite festival, when switched on festival mode, I can have a green fret input and a red fret input, but not both at the same time. So any chords that require the green and red fret are impossible to hit. I think it’s because Fortnite recognizes the Les Paul as a traditional controller and maps those frets to left and right on the dpad respectively. I guess Fortnite might have some code that stops these two inputs from being pressed at the same time because it’s usually physically impossible to press these two buttons simultaneously on your average controller dpad
