Yeah, that was an epic fail. They should publish the sound engineers name so no one ever hires him/her again.
I know for a fact the FXII doesn't sound like ass, so that was giving all modelers a bad name.
If anyone wants de facto proof that FXII isn't there yet then read the UPDATES to firmware.
Kemper is not upgrading it's profiling or algorithms for amp modeling.
But the AXE is. Continually.
Quantum update:
9.01 Improved Speaker Compression algorithm so that the change in the speaker impedance is accounted for.
9.03 Improved power amp modeling.
IF the FXII had arrived at amp realism, it would not need continual "improvements" to it's basic amp modeling.
If some here don't hear the different, great! Hearing loss, fanboyism, or just preference wins the day. Sleep well.
But Chris hears it and continually improves his product. I hear it and keep the KPA for it's amps.
They are minor. But the plain fact is: The FXII hasn't arrived at true amp realism yet.
Nor will it through the FXII. It's probably not powerful enough for it's approach to modeling. Hence... The much more powerful FXIII.
Kemper rested his case years ago when he said Improvements to profiling and amp modeling are DONE. Onto the other things.
So people can stop pretending there is total parity. There isn't.
The KPA beats the FXII in amp realism on many amps, if only even if by a hair. It's hard to hear when you use effects is why ppl are fooled.
And the FX has some better effects than the KPA. This leads some to prefer the FXII. Others own both and mix/match. They make a good pair.
