First thing you need is to convert your mp3 into something that can be imported into Kristal (it doesn't import mp3's as far as I can see) - the most practical will be to convert it into a .wav file. There are various pieces of software that will do this for you - I either use MusicMatch, Audacity or dbPoweramp all of which I happen to have on my machine but you can use anything (beware a little of some of the internet offerings that love to fill your machine with cr*p and trojans) - Audacity is good and solid and useful generally and will also allow you to create mp3's so may well be worth downloading - it's at Audacity if you want it.
All you then need to do is open the mp3 in Audacity or whatever and convert the file into a wav file. Once you have that file open Kristal and the Kristal waver window comes up. The leftmost icons under the box entitled 'Waver 1' allows you to browse your computer and open a file. It will then import the file you want and you can start butchering it! It will import it as a stereo track.
