Well, There used to be a demo where Michel Voncken demonstrates the Tyros in English on the european website of Yamaha, but I can't find it anymore, but I still have it on my Harddrive so I can upload it to my server if you want me to.

P.S. Michel's English is okay, I can still understand him perfectly well (And English isn't even my first language!).
