I was looking at that – seems to provide smiley face curve eq on the countour or mid rise honk to it. Then applies a Limiter to the whole thing.
The Tilts only tilt on bass heavy side, lowering hf or hf side lowering lf side. If you want to use on stereo channel – make sure you group (Stereo link) the channels together for a stereo channel, that way you get to assign fx to both at same time.
If you’re unsure what the setting does – convert the channel to “Complete” (top right drop down box).
These are really bass guitar EQ, made popular by Trace Elliot. To be honest apart from using the shape as a type of loudness setting, I am not sure it is useful.
