Nice demo...
I still have to confess, it confuses me to see all that wasted real estate to the sides of the keybed. If you are going to make something virtually as wide as a 76, why not include a 76 and drop the wasted space? Move the wheels up to above the end of the LH (like Ketron), and you could get a 76 with virtually no change in size.
Diki, I hate where the wheels are on Audya. You wouldn't think that few inches to reach would make a difference, but it does. I can reach the joystick on Roland almost without moving my hand.
I do agree the Tyros is too big for a 61-noter though.
