The solution should be something like this (I think):
Use PlaybackLoudness property only on clients and change the function inside the module (remove PlaybackLoudness in the module).
Are you talking comparing the two values
Like have a variable in the module that is the “old” playbackloudness, and for each frame compare the two of being > \ < each other?
Well, I didn’t have a rhythm mechanic in mind, I wanted to fire a function on the loudness changing, but seems promising will look it to it
Never know could reverse engineer it
