Nice demos. Thanks for sharing the links. I too think the Korg has a winner in the Pa3X.
It has a very live and open sound but one thing that struck me was that the volume levels between variations don`t seem to be very even. This could of course be corrected by tweaking, normalizing output through some audio gear but since it was right out of the box it didn`t sound so even. All the individual voices showcased are nice. With the flexibility of this keyboard, owners will have a lot of tweaking options.
While checking some of the you tube videos on Pa3X, I came across the UK launch videos of the Pa3X. This would give you
an idea of how it may sound on stage !!!
May be you have heard it but here it is anyway :
