Needs an update

This app used to work perfectly in conjunction with the THR amp. Unfortunately now it doesn’t allow you to play tracks you wish to practice/jam along to, so a bit unless currently... Please update this Yamaha!

Does not work correctly on iPad

This app should be brilliant but it's not
It will not allow me to upload a song from my library so rather defeats the point of it!!
