I could be wrong but I believe the KPA was released in 2011. The Axe FX II Mark I & II were also released in 2011 and Fractal Audio actively releases new firmware updates for them.
Well here is what we know. Christoph is the creator of synths through Access with, I think, 3 major products, the oldest over 16 years old, and all still supported. Now he has the Kemper company (is Access the parent company?) that has this product and it's got a few incantations (lunch box, rack, differing colors) but essentially the same in terms of no differences with how the software runs on them or support for them all.
Compare this with Fractal, the AXE and ULTRA are no longer supported. Mark I/II aren't backwards compatible with presets because of HARDWARE limitations, unlike the newer XL and XL+ versions. So we see the chopping block coming at some point perhaps.
Now, nothing wrong with this in terms of how the market does electronics and Fractal in particular. BUT... I have a choice, and there being a choice, I certainly am concerned with longevity and so.. I choose Kemper on this account in a big way. But not the only reason, just a big one.
