Help please!!!!

i got an mpc 2500 i got samples chopped up and recorded my own loop from them and on different tracks got drums etc.. when i have only 1 playing it sounds fine but when i unmute them all and have them all playing together it still only lets 1 sound from each track play so its all jumpy
can anyone please help me? it wont let all tracks play the whole loop at once???

maybe check the poly/mono voice option of the program. could (should) be the answer, if all of your samples are in one program.

yeah i already did all that but doesnt change a thing. ill give it another shot would it matter if there in different programs?

doesnt work still only lets 1 track play at a time Frustrating me beyong beleif can anyone help?
