But here's why I'm not keeping it:
I have gotten spoiled to being able to have dedicated buttons and sliders for virtually every function I use. Everything is easier for me on both the Korg
It's the LITTLE things, such as printing at the top of the keyboard where the connections are located...having an indicator light to show whether the vocal harmonizer is engaged... a Leslie emulation that works with preset voices...dedicated sliders to adjust style and lead part volumes on the fly...more foot switch connections...location of the USB ports...no XLR mic input...no phantom power...having to go into a menu to adjust the key on audio files, using the transpose button doesn't work there.
Most of these features are on the Korg PA4x, which I admit is twice as much money, so should be better. However the keys on the Korg are heavier than I like, as is the keyboard itself, so I was looking to replace it.
It's great that there are no bad choices, only what works best for the individual!
All those little things you mention are all strong points that keep me keeping the Pa4x. For me the heavier keys are a real plus.
