MPC1000 Problem - faulty?

thanks for the fast respond. tried it over and over but it doesn't work. tried it with different rams as well (one of them even original akai).
i uploaded an audio file, so you can hear what i'm talking about.
i'm running jjos1 maybe this could be the problem?

cheers

or are you talking about the original 16mb ram? is it even possible to remove it?

Nobody never had the same problem?
I can't even play samples from the flashcard (new card, new samples) while loading, i always get a glitchy "beep" when i end a played sample (samples with deep frequency are worst)

if i knew at least what to replace id be happy

dancin with myself...

anyway i finally got it!!

solution quite easy: reseted my mpc -> reinstalled akai os -> reinstalled jjos -> no more glitches

edit: well maybe any form of installation/update works.. what i described was the first way i tried it with new os files and it helped.
.. if anyone cares
.. yeah language skills
