i think Kontakt is excellent for mapping sounds across the keyboard, but since you are having technical issues then i think your a bit out of luck there.

I TOTALLY understand you when you say that Kontakt is a hassle to audition samples with. The sample doesnt sound when you click on the file, instead of you have to press the audition button evry time u scroll to a new file.

I think the latest version of Kontakt has solved that issue though, but you should check out the NI website just to be sure....
