Actually both of you are right..
Its Varranger with the latest SD9 soundset loaded in the buildin softsynth..
And its indeed a Ketron style..

Here an example of the same soundset with a Korg style.
So Korg style and SD9 soundset.

Personally i think with these new soundsets Varranger has set another step..
And this is just the base, playing rightbout of the box.
you can allways add high end VST’s and effects to improve this even more
