Feature request: Envelope follower or control parameter with sidechain

What the Audio Component’s Envelope Follower does in UE4 is it basically calls an event that passes the envelope value which can be used for simple procedural lipsync (Video example here)

As of the time of writing (April of 2021), we do not support getting the output value of a sidechain effect or envelope follower DSP effect.

In code, you could potentially use DSP::getMeteringInfo to get the metered output of a DSP unit. This feature isn’t available through blueprints, but can be accessed via code. Would that serve your purposes?

Alternatively, you could instead put a sidechain modulator on a parameter, link the modulator to a sidechain somewhere in your FMOD Studio project and use the value of the parameter.
