Most important however are lemur and touchOSC apps, that turn the ipad in a fullfledged controller for kronos, tyros5 but mostly for Macbook running mainstage...
My ipad is the most versatile thing i ever owned, next to being versatile its also rockstable and unbreakable
Bachus, could you describe further how you control your Tyros 5 with your iPad?
