Someone out there must have a Tyros2 and still have the CD editor...here is PSR Tutorial's link, just look at the top row, and click on forum at the far right.

http://psrtutorial.com/index.html

Registering is free, and there is a pile of info on the site proper and the forum including an excellent section, Understanding PSR/Tyros Features | Secrets You Won't Find in the Manual

Just post in relevant sections, and of course, state where you are (USA), and maybe someone there can help?

You could also contact the nearest Yamaha dealer, and order one if all else fails.

I really wish I could help more.
