Octatrack Receive Midi Configuration

Hey all, almost got the rig speaking clearly to eachother. I’m sending notes from my minilogue(ch3) into the octa, and the octatrack is spitting it back out into the minilogue to loop. I also have a monosynth(ch1) receiving notes from the mini instantly, as well as notes from the octa when I record the notes from mini to octa. One problem; sometimes when I press a note on the minilogue it will completely change the pattern in octatrack and erase assigned channels when part changes with that. Any way that I can make the octatrack only receive notes from the minilogue?
