NOT MY DEVICE ... BUT SO HELPFUL!
Added 2021-09-02 08:33:40 +0000 UTCLinked below, this is the "Volume Compensator". Folks have been asking about it after seeing it in some videos! Put it before and after your plugins and it will compensate for the gain added by FX plugins. The benefit is that you can simply listen to the details being added, over volume being added. (Sometimes this plugin can add a little latency to the instrument, so after I note the compensation, I'll often turn the device off and use the "Utility" device to bring the gain down at the end of the FX chain).
