v0.40

Cross-fades between two input functions, either based on a parameter or on a third function.

A mix value of 0 is the first, 1 is the second. Values outside that range will linearly scale, as though the two input values are two points and a line extends off in the same direction on each end.

Parameters

Name Description Regular Handling Read-Only Handling
Enable
Mix
