unwanted midi program changes

just switched to os 2, and every time i hit play my programs instantly change on the triton. this is making me want to break things. it happens for every one of my projects involving midi and the triton.

any help?

never mind i completly disregarded the pc option.

I'm not familiar with the jjOS but on my standard machine I disable Program changes as follows:
Pgm: > No.1
WINDOW
Make the YESs NOs
Any help?
