If a kong is created, and the pads do not sound...can you still use the piano keys to play Kong? If so, perhaps you can "octave up/down" the pads until you find the spot.
Additionally, you might want to check in the axiom manual about its "presets" if any of those or the default one Is a current Reason template.
Sorry I couldn't be more help, not familiar with the axiom. Does it have its own editor? That might help too if all else fails.
