Samples playing back wrong

i recently got a mpc 500 and the thing is driving me crazy... i am no novice to midi or music production but i am having more problems than i ever could have anticipated with this thing...lately i have been loading samples, that i would like to loop and/or sequence drums over, and they seem to function fine until i try to trigger it in a sequence and it will only play for about an 1/8th note...i've tried both one shot and note on settings, as well as loop on/off...any suggestions????

I have the same problem, when i have some sequences saved and i want to make next one, the samples from previous sequences stop playing after I hit the pads.
Could anybody help us... please

1. Check if the pad isn't set to mono
2. Check if you aren't usinng mutegroups
3. You might be out of voices/polyphony so long samples stop playing

1 and 2 are set in program mode.

3 is a hardware limitation, MPC(500) was not meant to play long loops I guess. Try chopping a long loop in 4 pieces and trigger those.

Thanks,
I did check all of those things. It turned out my 500 was busted and I wound up exchanging it.
Peace.
