I successfully set up a way to control the volume of all the separate sound waves playing in my game using sound a control bus mix populated with a seperate control bus for each sound wave, each control bus being linked to a modulation parameter setup to deal with volume (dB).
Now I need to do the same thing but instead of controlling volume I am controlling a LPF. So I repeated the exact same process but with a new control bus mix called LPFControlBusMix and wired it up the same as I did in my volume control setup.
I populated my control bus mix with new control busses specifically made to deal with a separate LPF.
Each sound waves modulation settings are setup to go to their very own low pass modulator.
Each low pass control bus has the same LPFCutoffFrequency modulation parameter in it.
My au.debug.soundmodulators debug command is telling me each control bus is correctly having its LPF normalised frequency set to 0.5 just as my blueprint told it to but when I listen to the audio no such change has been made. I even play around in the editor adjusting the frequency in my control bus mix but no change can be heard.
This is the exact same process I did for setting up my volume control system and that works fine. Are there some extra steps to setting up filter controls using control busses that I am missing?
I am in 4.26.2
