Of course it is the same technology, Bachus; it is a "Tyros" after all. In fact, the basic engineering goes back quite some way, but mostly back to the original Tyros.

It works, and it works successfully, both sonically and economically.

If it were to be a completely new instrument, with a new sound generator, and other new technology, it would not be called a Tyros model anymore...it would have a new name.

Korg's last free update was when?

I doubt you'll see anymore, if there is a new Korg PA on the way.
