I also have a Tyros and find it to be the answer to a long held dream.
The dream being a great sounding board with enough outputs, and inputs, and styles and hard drive and computer connectivity. Also it's pretty easy to figure out.
I've had Roland hard disk recorder in the past and it took me two whole days plus I had to buy the video shortcut tape just to add effects to a track. So I can understand your frustration with non intuitive equipment.
The thing about the Tyros is, if I don't understand something in the manual there is plenty of help on this and other forums.
