Problem with MPC Pad 187 for Mac. Some .wavs will not load.

Ok, so i made a program in the Mac application MPC Pad 187. I used all 16 pads with a different .wav file for each. On my mac, when i press the pads in MPC Pad 187 all of the .wav files play correctly. I didn't change any values within the program, all i did was select the pad, drag and drop a .wav in, and move on to the next pad. I filled up all 16 pads and exported a new folder to my desktop. All the .wav's and the program file were inside the folder. I dragged the folder into my MPC 1000. When i loaded the program from within my MPC 1000 it appears to have worked fine, however two of the pads wouldn't play anything. The other 14 samples all worked, but two wouldnt play, even though they WERE inside the folder on the MPC. To make matters worse, i made a NEW program within mpc pad 187 with entirely new samples and now only ONE pad will play. Just the top left pad. When loading the samples on my mpc1000 it only showed the one sample that does play being loaded, even though all the .wavs are in the folder correclty in the mpc1000.

Very confused on why it's not loading certain .wavs

Any idea what i'm doing wrong?

(note, all .wavs are UNDER 16 charas file names. i read that could be a problem)

Cheers.

can you load the individual samples, not by loading the program


if not, they probably aren't 16bit 44.1 kHz format
