My Keyboard is Changing the Sequences!!!!

Hey, Im using the MPC 2500 with the fantom fa 76. I have the reg "handshake" midi hook up and it all works perfectly but when i go to change the sound in the keyboard the sequence changes. This is really anoying when brownsing through sounds. Ive had a flick through the settings in both the keyboard n frm what I see its all gud, Im prob missing sumthing tho. If any1 has had this b4 or knows what the prob is Id really appreciate any help.

Im not familiar with either pieces that you use but it sounds like theres a problem with your system settings with the fantom. make sure that the program change is turned off.
