Hi Dan, suppose it really depends on what functions you use, it’s just not as complete a workstation as the PA4X is, but it sure sounds great.
Having a dual style player is incredible, and the matrix pads, if and when they add some new functions aught to be amazing.

List of what they’re planning on adding back in ( so in short , currently missing)

I could be totally wrong, but if I remember correctly , you couldn’t view the names of individual Korg styles in a pc?, they were saved in banks or sets?
now works just like Yamaha system,
you can see the styles individually in a pc , move them round between memory sticks, back them up on your computer , makes it so much easier to sort them.
