About the new Get Modulator Value function feature on 5.2

Added a new Get Modulator Value function to enable Modulation sources to drive other systems

Hi everyone.
Can anybody shed some light on what this new MetaSounds function is and how it works?
I’m wishfully assuming this means we can now use MetaSounds modulators like LFO’s, envelopes, (and triggers?) etc, to drive other systems, is that so? Anybody doing this?

Thanks

Hey @fcorona
This function is new to Blueprints in 5.2, it has actually been available in MetaSounds since 5.0.
It refers to the Audio Parameter Modulation system, meant to replace Sound Classes / Sound Mixes as the new method of audio mixing in the engine.
A modulator can drive a sound’s volume / pitch / filtering etc, or any other realtime parameter in the game world, with data coming from any modulation source or generator. Definitely worth checking out in the docs !
I’m using it to control various aspects of my mix in one place, and like it a lot

Thanks ebarkani

I was naively hoping it was the modulators inside MS (like LFO’s, ADSRs, etc) which could now be read as output data to drive other systems, but will definitely look into it, perhaps I can get a similar result with this method.

Best!

The catch is that it only returns normalized values, I am currently looking for how to get the upscaled value here, if you’re interested:

Feature Request: Audio Modulation, get upscaled/unit value in BP

Hi everyone, in BP it is possible to get the normalized value of a Control Bus via Get Modulator Value node. How can I get the actual scaled value, as descripted in the underlying Audio Parameter? I tried to write a utility function to do just this, using FModulationParameter::UnitFunction. But linking again AudioModulationStatics proves to be veritably difficult to get right. Having this as a utility function would be nice for usage in BP. I have some sound aspects living there, and not with…
