Nice find Mike.
That guy is so good he can make whatever keyboard sound great!
Nice "demoshow", because he do use the keyboard as many, or maybe the most of arrangerkeyboard players do, play with styles and sing via PA and harmonizer.
Quite surprised about that they don't promote the Musikant version here in Scandinavia.
That said, here they don't promote Korg arrangers any much at all anymore, you hardly find any PA4X within a range of 2000km from where I live. (and I live very close to the 2.nd "big" city in this country)
I did ask at the largest musicstore via webchat, Korg adverts gone from the site, and they only take preorders.
I can also see Thomann and others sell on request, and it's quite a long deliverytime.....
I guess low sales are mirrored by the lack of used PA3X for sale too.
(Of course this can be different in other countries.)
