I've noticed that when I download some of the Yamaha free Premium Paks, some of the folder contents are labeled Genos as well as T5 for the Tyros. To save download space in the Yem and my Genos Expansion folder, should I delete the Tyros info, as I only want the Genos info, or is there some data on the T5 folders that the Genos may need to access?
