From TouchDesigner 099 Wiki


The Trail CHOP displays a history of its input channels back in time. A window of time is displayed from the current frame back in time, the size of this window is set by the Window Length parameter. The last sample in the Trail CHOP is a sample of the input at the current frame.

  • Only When Input Cooks /inputcooks - captures the input only whenever the input cooks. Useful for capturing discrete events separated by long pauses.
