It looks like there is a way to convert the songs I’m looking around for it.
Yeah I know it’s possible on PC, but for Xbox I’m not sure. I have an RGH if that makes things easier?
why not use rockband? there’s a ton of created songs for that
No idea hahaha does it require a guitar or can i use a standard pad? on gh3 i can use a pad
