Fortnite Festival - Ride Wit Me 100% FC Expert Normal Lead (GH Controller)

Nelly featuring City Spud - Ride Wit Me in Fortnite Festival on normal Lead.
It sure would be nice if Pro Lead & Bass supported more than two controllers on PC as of the time of this upload, or if other methods I've tried so far such as the FestivalInstrumentMapper program didn't lead to the 'Swap Device' message making Pro modes impossible to play (although the existence of that program is extremely appreciated). Hopefully this won't be a problem sooner rather than later, as the 5 Fret community has been very proactive in their attempts to get more than the RB4 Stratocaster and the PDP Riffmaster to work with FortFest. I'd like to use the controllers I prefer over the Rock Band-style controllers the game currently supports, and already have as well.
All Fortnite Festival gameplay is done using a Wii Guitar Hero III: Legends of Rock Les Paul guitar controller with the RetroCultMods V3 Wii Adapter WITH TILT for Clone Hero, unless stated otherwise in another video.
