Wow a lot being said here about the Korg Pa3x. I have just come off many years of using Technics keyboards and my move will be to a Korg keyboard so the posts here gave me something to think about.
My first thought; I feel the people who do the demos maybe thinking of the song as in I’ll play this song it is really a good tune. Instead, in my opinion, it should be what song can bring the great parts of this Pa3x out. The keyboard is good but the wrong song can kill the demo, as in this case. So the negative remarks maybe may have their place here but after playing a Pa800 for the last month I can only agree with the demo is poor.
I would like to make a statement about keyboards; I do not feel it is not possible to know the capabilities of a keyboard from a few demos or playing for a few days. It takes a while to understand the true beauty of any keyboard. If your desire is out-of-a-box and play then it cannot be a Korg. Possibly a Yamaha or a Technics, they were great right from the start but they do offer less in many of the important areas.
Korg is offering me options that will help make my performance better. (Does this sound like a Korg commercial, oops.) Smile.
Just my humble opinion, John C.
