I'm happy to see I'm not the only one that thinks the Tyros manual is confusing.
After many fruitless attempts to find another Tyros owner in Arizona to share the miseries of studying the Tyros manual, I finally found some outstanding help.
This help is from Simon Smith and his CD set called Tyros Made Easy. It has opened a whole new world of knowledge in understanding the power of this keyboard.
I was amazed at how complete the information is and how well it's presented. It must have taken great dedication to put it all together. So far it has answered every question I've had, which were many.
If you find the Tyros manual as useless as I have, consider looking at Simons work. You'll be glad you did.
