Automation Curve

Overview

Creates a free-form "time → value" curve (AutomationCurve). Define arbitrary motion shapes that standard waveform nodes such as sine cannot express—for example, a hold followed by a sudden start and a gradual stop—using presets or a JSON sample sequence.

Usage tips

• Start with a preset for the quickest setup. Supply a JSON sample sequence when you need more elaborate motion.
• If the nine options in ease_in_out are enough, that node is simpler. Use this node when you want to design the shape of the curve itself.
• Connect it to a compatible node with a curve input to drive a parameter over time.

Generates an AutomationCurve from a preset or JSON samples.

Ports

Parameters

• duration: Duration of the curve
• samples: Number of output samples
• preset: Flat / Rise / Fall / AttackDecay / Wobble / Json
• json_samples: A JSON array of values from 0 to 1, shown only for preset=Json
• output_min: Output value when the curve value is 0
• output_max: Output value when the curve value is 1

Notes

Version 2 supports presets and JSON input. Known legacy lowercase values remain accepted for compatibility, but any other unknown value is an error instead of silently selecting a default. Invalid JSON is also reported as an evaluation error without replacing the entered text. A dedicated CurveEditor UI remains a future extension.
