Mono2Stereo behavior on stereo signal

[Yinxi]

Hello,
Just wondering, what happens if you use Mono2Stereo on a stereo input?
Does it leave the stereo signal as it is, or does it sum it to mono first?

I’m trying to make sure it won’t cause any unwanted channel collapsing or weird phase behavior if I use it in a ScriptFX that might sometimes receive stereo input.

Thanks!

Ya try it out. Just an assumption, but most likely it is going to take the first channel (usually the left) and just duplicate it. For all intents and purposes you can just use a multi or split container.

No need to guess what it's doing:
