It looks as though you've got some conflicting MIDI mappings.... I would check through all your mappings again (e.g. the control knobs 2 and 4 that are loading things from the media bank) and see if you can find any conflicts. I'm not certain about the DJM-800 and APC 40, but you may be able to change the channels on which these devices are broadcasting their MIDI messages, which would help to resolve and conflicts.
