@johanibraaten I think this comparison makes it clear what you meant by elements of the tone being closer to the SK-EX.
Here's the excerpt from the real SK-EX, it's of course glorious, sparkly, crazy resonant, and the bass is ridiculous.

For the rest just jump to 1:52
Here's a modified NY D Jazz Pianoteq version

Yes David I know it sounds to you like nails on chalkboard, but to the rest of you (perhaps @srodrigo since you've been looking), isn't the Pianoteq version a tad close to the SK-EX one? (very different performance of course).
The bass for me is actually what's weakest in Pianoteq.
