It’s for whatever you might want to use it for, I suppose.
The Q strength, Frequency Offset, and Gain strength knobs on the bottom give an offset to all the bands. You can control which bands are controlled by those knobs by clicking on the power buttons next to the Q setting of each band. Again, these knobs are just global Q, Gain, and Frequency offset.
Nice feature to have the Stereo/Mid/Side options on each node.
Is there a way to isolate or preview the node you’re working on?
Also, what if you had Tooltips that you could turn on/off, so when a user is first getting to know the plugin, you could get a brief explanation or “Help” by mousing over the item in question?
