ESX24 basic sampler question.

I tried my hand at sampling an accordion sound from my keyboard for the first time.I recorded a wav file of a C note for 1 measure & then loaded it onto EXS24 choosing the Zone-Load multiple sample. (I didn't see an option for a single sample in the drop down).Anyways to my surprise EXS took care of it & mapped the entire keyboard with just that 1 single note.The only issue I'm having is that when I press the note for more than 1 measure on my keyboard,the note dies! What do I do for the note to remain as long as I press the key? I even tried copying a 1 measure sound from Logic loops library of a vocal sample. But I am still running in to the same issue of note dying out.

Any guidance would be appreciated.Thanks.
