File file - The path to the VST3 plugin. Default install location for VST3 plugins is C:/Program Files/Common Files/VST3 on Windows and /Library/Audio/Plug-Ins/VST3 on macOS.

Reload reloadpulse - Reloads the VST3 plugin.

Sample Rate rate - Sets the sample rate of the VST3 plugin.

Plugin GUI Always on Top alwaysontop - When enabled, the plugin window will always be on top of other windows.

Display Plugin GUI displaygui - When pulsed, will open the plugin GUI in a separate window. Changing a parameter in the plugin GUI while the learn toggle is enabled will create the parameter on the Audio VST CHOP side.

Parameters - Common Page

Time Slice 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 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.

Export Method 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 geo1/transform1:tx.

Export Root autoexportroot - This path points to the root node where all of the paths that exporting by Channel Name is Path:Parameter are relative to.

Export Table exporttable - The DAT used to hold the export information when using the DAT Table Export Methods (See above).
