MIDI drift / problems with LOGIC PRO + MPC 2000

The problem is pretty obscure .... I couldn't find answers in the search.

I can get Logic and the MPC synced up no problem (via MIDI TIME CODE), but when I record seperate tracks into Logic from the MPC , they don't start on the '1' of the bar , they are just a few frames early , but everything still sounds perfectly in time! It is pretty f*cked actually. Technically since it sounds ok it should be ok, but something isn't right, it should be right on the 1 of the bar.

Also the MIDI has been drifting, so when I record in a few different tracks and lets say I want to do a new snare pattern on the MPC and record it in over the previously recorded parts , the timing will sound right when I record it in, but once I playback the recorded part, the sh*t is out of time!

Oh, and I'm running a MOTU 828 and an EDIROL UM-3EX midi interface.

Any ideas/info it would be greatly appreciated.

I'm not familiar with Logic, but there should be an option called Midi Delay Compensation or something similar to it. Every descent program has it, so I don't suppose Logic is an exception.
It should help to solve your problem.
