Program Problems

Currently when im making a kit on my MPC 1000 while loading in samples into the pads, some go missing. Like for example i turn on my mpc and i start loading in samples and like halfway through many of the previous loaded samples just show up with a question mark right next to them. And even when i reload them in they seem to go missing after like 3 mins. Have anyone else had this problem. Any help would be appreciated

i noticed the same problem, when i create a program with mpc pad 187 some files do not appear.

Do you hear the samples after u loaded them ?
i had the same thing with the question mark because some sounds were at 24bit...

yeah for sure i heard them while previewing them before and after loading. Has anyone had this problem withe the MPC1k
