Unity how to check if parameter is being changed?

Hi there I’ve set up an adaptive music system in unity and got some good results however one of the parameters ive set up doenst seem to trigger the transition region even though I’m using the same method for another parameter. I cant seem to figure out why, no null reference exception is being thrown and was hoping someone could shed light on exactly how I would go about seeing if the parameter was being affected at all in real time by the game. I havent had any experience with debugging fmod so far and cant seem to find much info on how I would investigate this parameter change instance further. Thanks
