scary problem

iv just turned my mpc on and loaded a folder of samples manually all correct wav. files....but sum pads seem unable to play the samples. althought these pads are still functioning when opening up mode screens they just won't play the samples...iv turned it on and off a few times to no result...
please any helpers

have you also created programs where you're assigning the samples to each pad?

Make sure all the wav files are 16bit.
