LayerInOut

The entry and exit for pulling the video of the selected layer into the node graph and returning the processed video to the same layer.

The output of a Layer node is not an echo of the input, but the actual value of the layer chosen in the dropdown. Even with nothing plugged into the input, values you move from the Layer window or over MIDI come out of the output, so you can use the layer’s state to control other nodes (a bidirectional design that is both a write port and a read port).
