direct recording

Hi, I've got a wierd problem.I've made a song and then I tried to record guitar to this song.so I choose direct recording and everything goes sweet.I record it and I save it (with for example pad A12).but the problem is- when I play this song and I press the choosen pad,the guitar sample I've record doesn't play all the way.it's playing just a beginning of my guitar sample.please,please,please can somebody help out there:) because when I play this sample on his own-it goes all the way but with song -just a bit???????

maybe sample is too long for memory? its all i can think of

I've been thinking about it.but I have upgrade my memory and this is not the longest sample I've got.I tried record it for many different ways--but it still the same.and funny think is that for any other songs it working properly??Don't know what is going on

Is the Pad set to Note Off or One Shot? Is the Program set to Poly or Mono?

Ahh, always the same ol' boring questions...

I've tried with both (note off and one shot) still teh same.I'm gonna check it if program is set up to poly or mono-can't remember now.do you think that maybe a reason??

program is set up to poly,any ideas??
thank you and I hope somebody can help me out there:)
