Hi. It's more of a bug, in my eyes, but Presonus support told me to post it as a "feature request". Oh well.
When I have two tracks sidechained, for instance track 1 is feeding signal into a compressor on track 2, track 2 is no longer affected by the Console Shaper in the Mix FX slot on the Main Out master channel (Console Shaper or any other Mix FX plugin, like Softube Tape).
I understand it's because Studio One doesn't want to affect the same signal twice and it's seeing that track 1 is sending its already wet signal to another channel. But the thing is that the signal from track 1 is only used to trigger a compressor on track 2 - i still want track 2 to be treated with the Mix FX plugin.
Is it possible for you to make it so that clicking the "Sidechain" button on an insert plugin (e.g., the compressor on track 2) allows Mix FX on the parent buss channel to still affect the track with a plugin receiving sidechain signal?
