Octatrack MIDI note mapping

Hey all, I apologize if this has been asked already, I couldn’t find a concise answer.

I am looking for a way to map only playable chromatic notes using an external keyboard.

What happens right now is if I press a note above or below the chromatic range, it toggles other settings. Which leaves me scratching my head at times as to what param got changed. I’m hoping to disable everything but chromatic note mappings using an external keyboard. Is it possible? If so how?
