Midi sync bug in os 1.23???

After tracking into Cubase...my track is slightly off at the end of each loop. Its the same problem when I split the beat at 9.1.1 and when I turn the mpc loop off, then track out.

I took my mpc to my producer friends studio and still the same problem. My homie tracks from his 2000xl with no problems at all. So, Im like what da hell???

What am I doing wrong and how can I fix this? Im using a firepod & Mac by the way.

your doing nothing wrong it's a bug and a problem that's been discussed millions of times on here I've personally sent akai messages like many others and no ones done anything about it but I'd warn you and I'm suprised that no one has told you to do a search but might be a good idea next time there's loads of info about this topic.
