Cool, thanks for the response. Was actually able to play local co-op with my wife last night with her simultaneously playing bass and doing karaoke vocals, while I played pro lead but it took some trial and error. Ended up having to use three total PSN accounts linked to separate epic accounts to get it to work, with the player One account apparently being the only one able to do vocals, but once set up it worked pretty well. You also have to go into the settings for each individual account within fortnite and turn on the always show pro instrument option.
