Sort CHOP
Summary
The Sort CHOP re-orders the inputs channels samples by value or by random. Specifying a channel to be sorted will reorder all channels samples according to the new order. This node does not change the order of the channels relative to each other. To sort the channels relative to each other use a Reorder CHOP.
Additionally an index channel can be created which holds the former sample index before sorting.
Parameters - Sort Page
Sorting Method method - ⊞ - There are three different sorting methods. CHOP samples can be reordered by increasing values, decreasing values or in random order.
- Increasing Values
increasing-
- Decreasing Values
decreasing-
- Random
random-
Seed seed - Any number, integer or non-integer, which starts the random number generator. Each number gives completely different noise patterns, but with similar characteristics.
Select Type select - ⊞ - Specify if the channels to be sorted will be specified by index or name.
- By Channel Indices
byindices-
- By Channel Names
byname-
Channel Indices indices - Specify the index of the channel to be sorted. All not specified channels will reorder their samples according to the specified channels new sample order. If left empty, all channels will be sorted.
Channel Names names - Specify the name of the channel to be sorted. All not specified channels will reorder their samples according to the specified channels new sample order. If left empty, all channels will be sorted.
Index Channel indexchannel - Enable to output an index channel which holds the former samples location before sorting.
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. See Pattern Matching.
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 hasgeo1/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).

Info CHOP Channels
Extra Information for the Sort CHOP can be accessed via an Info CHOP.
Common CHOP Info Channels
- start - Start of the CHOP interval in samples.
- length - Number of samples in the CHOP.
- sample_rate - The samplerate of the channels in frames per second.
- num_channels - Number of channels in the CHOP.
- time_slice - 1 if CHOP is Time Slice enabled, 0 otherwise.
- export_sernum - A count of how often the export connections have been updated.
Common Operator Info Channels
- total_cooks - Number of times the operator has cooked since the process started.
- cook_time - Duration of the last cook in milliseconds.
- cook_frame - Frame number when this operator was last cooked relative to the component timeline.
- cook_abs_frame - Frame number when this operator was last cooked relative to the absolute time.
- cook_start_time - Time in milliseconds at which the operator started cooking in the frame it was cooked.
- cook_end_time - Time in milliseconds at which the operator finished cooking in the frame it was cooked.
- cooked_this_frame - 1 if operator was cooked this frame.
- warnings - Number of warnings in this operator if any.
- errors - Number of errors in this operator if any.
