Axiom Pro in Cubase 7.5 Please help

Hi,
I have Axiom Pro61 (Cubase 6.5 - Win7 64bit) and I don’t understand how to use konbs (E1-E8) to control some instrument fx, like Nexus, some Kontakt instruments etc… works only PAN function for one track separately?
Is there somewhere presets for complete control of the instrument with Axiom?
Thanks in advanced…
