Roel,
I think the updates are to the USB-Midi Driver for the Tyros2.
I got a cd with version 2.1.3 on it and they have since updated to 2.1.4, then 2.1.5 and yesterday I got 2.1.6.
None of them work for me so there must be a problem in my computer with all the Technics stuff and drivers in it. I may need to clean house as the driver and utility program on that cd installed fine and works ok in my new Toshiba Satellit Laptop. The laptop doesn't have much installed in it yet so no conflict there. I guess I will get it all figured out one of these days.
