+1 on the circular knobs… >_< You can use the mousewheel, but it isn't precise. The checkboxes are a nice idea, if they were reversed, used to disable instead of enable fx. Not a bad plugin, not exactly revolutionary either.
It does connect to internet at launch, and the nags are too often to make it useable, would be better to either make it non-modal like a text on the display that goes on and off instead of the oscilloscope, or just once when you open the plugin.
The visual feedback is looking great, tho.

It could be called a demo, or it could be called nag-ware, but freeware is not.

Yes, it’s much more intuitive when you can simply drag a knob up or down to adjust the value.

But I tried it, and I totally hate the way you control the buttons… why, why, why…
You have to “follow the curve”, so when you go up, it reaches 50% max and then you have to go to the right…

I hate when developper take this route…

Well, the “lite” version has fewer functionality than the full, so it is really “lite”.
And you can download it for $0, so it is somehow “free”…
