It was a bit of a process downloading from the net then installing on my 4X. I actually thought I had done it wrong...but it worked! 😊

Gotta say...I'm impressed. What a great sound..love the new features.

It's great to get a new keyboard and not spend a dime. 👍👍👍

Gotta say, every time I play my 4X, I'm a bit blown away by its wonderful sound quality.
