Hi Brick,
ckemper has clearly stated that is not using IR, though it could think about an import routine to transform an IR in to whatever the KPA is using
I read about it not using IRs, I just wanted to know if there is any kind of simple explanation on how its done.
What I was trying to say was to capture an IR of the kemper cab, and route an amp profile (withouth the kemper cab) through the axe-fx II using the IR captured by the axe-fx II. You can then listen to the differences, of course some might account for the quality of the IR capture feature of the axe-fx II, but from what I hear I does the job pretty well.
