What happens when you reverse the polarity or edit the curve? Does that shadow change or always remain the same?

Michael, I'm just spitballing here but could that shadow be their way of showing that one of the elements in that selected part has a reversed volume curve?

Good question. It changes when you edit the curve. Now I'm even more curious…

Hint: page 173 Reference Manual

I don't think they mean the screen blur. I think they mean the graph shadow in the curve type window.

See here for the grey shadow in this display:

Assuming you mean the Blur setting, that's not it. The curve shadow is there just the same whether Blur is on or off. It shows up much more noticeably when you're looking at the actual screen than when you're looking at these screen shots.

I've attached an enhanced snippet of my original attachment so you can see better what I'm asking about. It doesn't show up that well in the thumbnail, so please make sure to click on it and look at the actual image.

What I've noticed is that the shadow part is available to the control, but not the parameter.

That is, say for a unipolar setting, the control throw itself can go from 0 to 128, but the parameter only has 0 to 64 as a maximum setting.

The bright portion shows what is available for the parameter being controlled and goes to 64 showing that to be the max. Going any higher doesn't do anything as it maxed out at 64 although you can go higher with the control, it, just doesn't do anything to the parameter under control.

That may not be right, haven't played with it enough to know, but it's what it seems like to me.

The "ghost" image shows you the shape of the Curve Type you have currently selected.

If you remember the old Motif XF, what was controller "Depth" was always linear, either "+" positive, or "-" negative but always linear, now the Curve is selectable and programmable and is not always linear (Linear is now just called Standard) Change the Curve see how the ghost changes to show you the *default* setting shape for that Curve. The Param1 and Param2 warp that shape. This is the application of your controller to the Destination.

Change shape (Curve) to Sigmoid, notice the ghost changes shape to show you the default Curve. Your settings will offset from the default Curve's shape.
