Having a tilt screen is really nice and easy to become accustomed to after a few tyros models. Add touch and it must be that much better.
For me ..
The Tilt up display is an essential feature for many reasons.
Touch screen makes the workflow fast and easy.
The Pa1000 layout is is quite good and navigationaly functional
for live play too. A few sliders would have been nice.
But it's all there for the pro player for sure.
The deep editing capabilities is where Korg shines,
drum kits, styles, sounds , VH, etc,...
