no dat really aint how u do it. well if u jus wanna cut the note down to a few seconds then yea dats how ya do it. but wut i thinkur askin is how come it keeps playin after u unhold the key or w.e. on each sample window thing is shows the sample wav picture or w.e. u have to go to the knob dat says "crf" and turn it all the way to the right. then if u press the note and hold it it will play but if u unhold it it will stop. hope that helped u kinda.
