All samples sound the same

I have loaded the MP with some loops in a folder but when I play them back on the MP they all sound the same
exacly the same I thought it was my ram that I just bought but I turned it off pulled out the ram then tried playing them with the internal ram and still the samething. I moved the files back to my computer and they all play as they should. Is there something i can do to change this other than recording one sample at a time to my MP.
thanks
BTW running JJOS1

You could rename them so the filenames are less than 16 characters long.

Edit: And RTFM

bit of a brief description. so it's hard to tell what's going on.
look in trim mode, do you see all the samples you loaded?
can you assign them to pads?

Thanks for your responses. I renamed some files that I was having trouble with and they started to work on my MP thanks again

The names don't have to be less than 16 characters, you only need to have one differentiating character within the first 16.

So forexample:

thatbanginsnaresample1.wav and
thatbanginsnaresample2.wav

would sound the same on the 1k, but

1thatbanginsnaresample.wav and
2thatbanginsnaresample.wav

would work correctly.

Thanks for letting me know about this.

Wrong.

The names MUST be 16 characters or less. End of story.
