Sonar Piano Roll and Kontakt

Hello peoples. I'm looking for a little help. Here goes.

I'm using Kontakt in Sonar 3.1.1. I import a wav file into Kontakt and map it to C3 in Kontakt's mapping editor.

Why does C5 in Sonar's piano roll trigger this sample? How do I get C3 in Sonar's piano roll to trigger this sample? Any help would be appreciated.

Mike
