Keyboard Media Controls

Need all the KB media keys to work like they do in Tidal and iTunes. Specifically the FF and REW (skip forward and back). I have harmony hub and alexa integrated so I can pause, play hands free which is perfect for my kitchen setup. I play playlists in general, with no access to computer or iphone, so when I hit a song I don’t like I tell it to FF to next track. Works in iTunes and Tidal but not in Audirvana. Will buy second licence once this works.
