Add: Add new value to input curve value.Scale: Scale input value by new value.Blend: Blend input with new curve value, using alpha setting on the node.Weighted Moving Average: Bend the new curve value with the last curve value using Alpha to determine eht weighting. For example, .5 is a moving average, higher values react to new values faster lower slower.Remap Curve: Rempas the new curve values between the Curve Values entry and 1.0. For example, .5 in Curve Values makes 0.51 map to 0.02.
