midi messing with my sounds when mpc connected to trition

I have everything set up right im sure but when I have a midi cable coming from my mpc to the trition and I start to play any sound at first it sounds fine but at a curtain point (im not sure when) when I start to play the trition every sound that comes out has an arpegiator on it. this only happens when there is a midi cord connected, it can be a bell sound piano, Im not sure whats going on but its kinda annoying sometimes I like it but it would be nice toknow whats causing it or how to turn it off/on. the arpegiator is set to off so i have know idea, please help!

Maybe you've got a MIDI feeback loop? Try setting the Triton to 'local off'.

I had the program part of the main page set to 'NO.1', I think that was the problem.
