This link will take you to Tyros Mania site which I avidly devoured when I got my Tyros 4. It explains everything that you need, don't need, know or don't know.
There is so much in there that I use but have forgotten where to find the information. There are many things in this package that even Yamaha did not know!
It was put together by Tyros Mania (Keith Ball), Neville Sharman, John Wyvern and others.
Take a day off and read some of it through, you will be amazed at what your Tyros can do.
There are also Styles and PDF info. Try it, you may like it.
