What is there not to understand. Also now some of the 2010 folder harmonies work, but as a side effect some random songs like some of the Green Day export songs now have wrong notes as the lead vocals. For example if I start the song Pulling Teeth by Green day as solo singer it uses the harmony of the song. This project you have made actually has damaged my official dlc songs. Lmao. I would suggest you to make a single working Con or Live file that has all the harmonies.
