This example shows required inputs only. Connection values like ["node_id", 0] should reference actual node IDs from your workflow.

1	track_length	INT	No	["{node_id}", 1]

How to connect to these outputs

To connect another node's input to an output from this node, use the connection reference format:

["node_id", output_index]

Where node_id is the ID of this GenerateTracks node in your workflow, and output_index is the index from the table above.

Example

If this node has ID "5" in your workflow:

• TRACKS (TRACKS): ["5", 0]
• track_length (INT): ["5", 1]
