sample on the pad

hello guys ... are new to this forum and excuse my English ... but unfortunately I'm using the google translator to write ... I am Italian ... Unfortunately in Italy there is no forum dedicated samplers AKAI ..

I wanted to help .. as is possessor just a wonderful "AKAI MPC 2000XL" ...

So the arrival ...
usually when I hit a pad and then leave, it continues to play its sample until the end ..

I wish that when I leave my finger on a PAD this end playing his sample ...

How do I do this?

I hope for an answer ... Thanks guys

go to program then to params and change the playback from poly or mono to note off.
