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.
Parameters - Trail Page
active - When On the Trail CHOP will record its input.
growlength - When On the length of the Trail CHOP's recording will keep getting longer as the timeline moves forward. Use this for recording any length as needed.
wlength - The amount of history recorded is set by Window Length. The Units menu on the right determine which units to use in the parameter (Samples, Frames, Seconds). A setting of 4 seconds will show the value of the input channel for the previous 4 seconds.
Window Length Unit
wlengthunit - Choose between using Samples, Frames, or Seconds as the units for the Window Length parameter.
capture - ⊞ - Determines when to capture values.
- Time Slice
timeslice- Captures a sliding window of the input every cook. Useful for capturing a continuous log.
- Only When Input Cooks
inputcooks- Captures the input only whenever the input cooks. Useful for capturing discrete events separated by long pauses.
resample - Enable parameter below to resample the output to a different length.
samples - Resample the output to this specified length.
setrate - Enable parameter below to use a different sample rate.
rate - Resample using this sample rate instead of the global frame rate (
reset - While On, this toggle resets the channel(s) to 0.
resetpulse - Click to instantly resets the channel(s) to 0.
Parameters - Common Page
timeslice - Turning this on forces the channels to be "Time Sliced". A Time Slice is the time between the last cook frame and the current cook frame.
scope - To determine which channels get affected, some CHOPs use a Scope string on the Common page.
Sample Rate Match
srselect - ⊞ - Handle cases where multiple input CHOPs' sample rates are different. When Resampling occurs, the curves are interpolated according to the Interpolation Method Option, or "Linear" if the Interpolate Options are not available.
- Resample At First Input's Rate
first- Use rate of first input to resample others.
- Resample At Maximum Rate
max- Resample to the highest sample rate.
- Resample At Minimum Rate
min- Resample to the lowest sample rate.
- Error If Rates Differ
err- Doesn't accept conflicting sample rates.
exportmethod - ⊞ - This will determine how to connect the CHOP channel to the parameter. Refer to the Export article for more information.
- DAT Table by Index
datindex- Uses the docked DAT table and references the channel via the index of the channel in the CHOP.
- DAT Table by Name
datname- Uses the docked DAT table and references the channel via the name of the channel in the CHOP.
- Channel Name is Path:Parameter
autoname- The channel is the full destination of where to export to, such has
autoexportroot - This path points to the root node where all of the paths that exporting by Channel Name is Path:Parameter are relative to.
exporttable - The DAT used to hold the export information when using the DAT Table Export Methods (See above).
