Doesn't look like a huge upgrade in OS but it looks like Korg listens to the users and fixes the things that need to be fixed. Gives me more confidence that Korg stands by their product and wants users to keep using it for a while.

Yamaha just keeps coming out with relabeled keyboards. It makes customers upset when they just saved enough to pull the trigger on, let's say a Tyros 3, and shortly after that, the Tyros 4 comes out.

I'm really leaning towards the PA3X for my update from my Tyros 2 and Motif XF. Only time will tell.
