I need a little Help

MY MPC IS PLAYING MULTIPLE SAMES WHEN EVER I PRESS 1 PAD.
IT WORDS FINE AT SOFTER VELOCITIES BUT WHEN I GIVE IT A LITTLE THUMP IT STARTS PLAYING MULTIPLE SOUNDS>

PLEASE LET ME KNOW THIS IS JUST SOME TYPE OF WIERD SETTING OR SOMTHING

the bees are on the what now

Yes , i had the same problem yesterday.
Previously it solved itself , but yesterday it wouldn't go away so i opened up my mpc , removed al the dust and dirt , made sure the pads are in the right place and at first it didn't change anything , but i tried it again and the problem was fixed.
I have no idea what causes the problem , but until now it was only temporary. Knock on wood.
Maybe i should just send it in to get the pad sensors replaced but i hate losing my mpc for three weeks or longer.
Greetz...
