Hi Dreamer, I loved my Pa2X and the SongBook, and frankly I made a mistake going to the Tyros 4. I am so happy to be back to the Korg interface and sound. The driving force was I really wanted to lighten my load and simplify my setup, and especially when I do really small jobs where I plan to use the internal speakers only. Then the price of the Pa900 made it a no-brainer

Btw I believe the interface on the Pa900 is simpler, there is not the Global save element; it just remembers the way you set up the global options. Maybe there is a benefit in the Pa3X interface, but not for me. I like this simplicity.
