Midi Feedback Loop Ableton (Chromatic)

Hey all,
Hoping you can help here…
When I am playing chromatically in Live with Overbridge, no matter what pad I am playing, I am also triggering BD1 every time whether I am playing in Ableton with Push or on RYTM’s chromatic pads themselves…
I have read that it is known as a feedback loop but can’t quite find out how to stop it from happening…
Any thoughts???
Thanks in advance,
J…
