If you have not heard about this, it is a new Program-Web site being done by Yamaha and they are looking for beta testers. It's basically going to be as way to download and purchase Midi Music and Sheet Music for Midi Instruments. They are especially looking to Keyboard Players and they say it will work with all Midi Keyboards. It is being done through a partnership (YMH)between Yamaha Music Interactive, Music Sales Group (of Europe) and Hal Leonard Corporation (USA) .

Here is what the say about it:

"Digital Music Notebook is a major new multimedia platform for music tuition and performance. It offers digital delivery of the world's best selling sheet music and tuition materials, synchronisation of all media within a single application, and the implementation of additional music tools."

There is not a lot there yet but if you are interested you can go to the web site below.
