Help triggering a part of a sound, not the whole sound

Hi

I have a problem, probably a stupid one, but i couldn't find it anywhere. I have just chopped a sample up and made it create a new sample, but when i trigger the different pieces the whole different pieces of course. But is there an option to be able to trigger the samples so that they only play when i hold down the pad?

Hope you understand my question

1) Mode > Program
2) Select the sample name
3) Window
4) Change from One Shot to Note On
