I do not own a Tyros. So, forgive me if what I suggest is already there. (I still use my PA80, but haven't lost interest in YAMAHAs.)

1. GUI front-end that runs on the computer (both Windows and OSX) but controls all or almost all parameters of the keyboard. e.g. Instead of changing the length of a note using numbers on the keyboard, click and drag on the computer so it changes the numbers on the keyboard accordingly.

2. I like speaker-less 61 keys. (compact and light)

3. Joy stick like on KORGs instead of wheels.

4. Just for the leg - preferably the left (I need my arm to play the Tyros once I have it) ;-)
