Transfer Sequence from Protools to MPC1000

Hello, I have a sequence created in Protools, and i'm trying to transfer each MIDI Ptools track to a track on the MPC's sequencer.
I already got Protools as the Master and the MPC as the slave. To record I hold the REC button on the MPC and press play in Ptools, it starts recorging fine. But when i play back what I recorded on the MPC the whole sequence seems to be moved 12 ticks to the right.

Any idea of what might be wrong?

Thanks
