### 2. New Range

Here you can change the range of an Animation Curve. For example, if min and max values are -5 and 6, you can project all the curve in the new frame range -5 and 20.

Drag and Drop your curve in the knob *Input* and use the button to find out the min and max value, then insert your new values and check in the Curve Editor your new curve.

In blue, you can see the original curve and in yellow the new one.

### 3. Smooth Curves

Smooth the curve with this tool. Insert your curve in the knob *Input*, select the Type *(High or Low)* and the power of the smooth.

### 4. Modify Curves

With this tool you can modify curves with: Translate, Scale and Time Offset. With the checkbox you can activate or not the modifiers.

### 5. Fade

Thanks David Ozols for the tutorial:

Create the fade/dissolve from start frame till end frame. Animate mix or another knob from 0-1 or 1-0

- Linear

- Slow-in Slow-out

- Slow-in Linear-out

- Linear-in Slow-out

### 6. Reference Frame

Here set a reference frame.

What does it mean? It means that your curve will be set to 0 in that frame. Basically it will be translated to 0 in the Reference Frame.

### 7. Percentage

Increase or Decrease the curve for a X percentage.

### 8. Average

This is a single value for the entire curve. It will return the average value for the curve.
