HELP¡¡¡ Problem with midi on my akai mpc 2500

hello im new on this forum¡¡¡ i have mpc 2500. and i have some problems with midi....

when i work with the mpc in slave mode....i can't stop....if i stop when i press play again sometimes i lost all on the track mute.......all my tracks on this sequence are deleted.....

if i work without midi, the mpc works good....

please i need HELP¡¡¡

yeah you can not stop because it is in midi slave mode.
This means that the start and stop are controlled by the master device that the MPC is slaved to and not the MPC which is slaved. This is normal behaviour.
