Program Change Issue

My Pyramid sends a Program Change message to my DSI OB6 that I don’t want.
It happens only for some tracks and when they are active. I have the same problem when I press the stop button.
I tried to disable Program Change in the Midi setting but with no success.
Can someone help me please?
(I have a live set this Saturday and I am desperate)

It might have recorded a program change if you were using live mode. Check your automations in Step mode, as well as the track settings in track mode (2nd + fx) and clear any unintended PC messages.

If for some reason you still get phantom program changes, as a last resort, go into the OB6 settings and disable program change acceptance.
