NOTE REPEAT PAD BUGS!!!!!

i have an intermittant bug with my note repeat pad
sometimes after a couple of bars the repeating function stops.
i have downloaded the latest O.S and it's still here!
who knows how to solve this problem?

the bug is only in song mode. when i convert my song into a sequence it works.

how much memory do you have

512 mo

i have tried with another mpc 4000 and i have the same problem; is it due to an error of programation in the sequences ?

i HAVE NEVER HAD THIS PROBLEM YOU SPEAK OF

Can you describe how to produce this problem?

if i knew how to produce it ,i think i would repair it :)
the problem seems to be intermittant,and i have it on both of my mpcs. :(
