Suno Extend

Extend an existing Suno-generated track by continuing from a specified timestamp.

Overview

Suno Extend takes a previously generated Suno track (identified by its Audio ID) and continues the song from a given point. This is useful for lengthening songs, adding new sections, or building multi-part compositions. The node requires a Suno Audio ID from an upstream Suno node, not a raw audio URL.

Configuration

Field	Type	Default	Description
Audio ID	string	""	Suno audio ID from an upstream Suno node (required).
Continue From	number (seconds)	0	Timestamp in seconds where the extension begins.
Extension Prompt	string (max 5000)	""	Prompt describing the desired continuation.
Model	enum	"V5"	Suno model version: V5, V4_5ALL, V4_5PLUS, V4_5, V4.
Title	string (max 80)	""	Title for the extended track.
Style	string (max 1000)	""	Genre and style tags for the extension.
Negative Style	string (max 500)	""	Styles to avoid in the extension.
Vocal Gender	enum	auto	"male", "female", or unset for automatic selection.
Style Weight	number	0.5	Influence of style tags (0.0 to 1.0).
Weirdness	number	0.0	Experimental output factor (0.0 to 1.0).
Audio Weight	number	0.5	Balance between prompt and source audio (0.0 to 1.0).
Use Default Parameters	boolean	true	When true, Suno uses its own defaults for advanced parameters.

Inputs & Outputs

• Inputs: in – Suno audio ID from an upstream Suno node (e.g., Suno Generate)
• Outputs: audio – extended audio URL

  Best Practices

• Set Continue From to the exact timestamp where you want new content to begin; setting it to 0 appends to the end.
• Use the Extension Prompt to describe the new section (e.g., “build to an epic chorus” or “fade out with ambient pads”).
• Keep Use Default Parameters enabled unless you have specific requirements for style weight and weirdness.
• Chain multiple Suno Extend nodes to build progressively longer compositions section by section.
• The Title field has a shorter limit (80 chars) than other Suno nodes – keep it concise.

Common Use Cases

• Lengthening a generated song that ended too soon.
• Adding a bridge, outro, or additional verse to an existing track.
• Building a multi-part composition by chaining Suno Generate into multiple Suno Extend nodes.
• Iteratively refining a song by extending from specific moments.
• Creating long-form ambient or background music by repeated extension.

Tips

• This node requires a Suno Audio ID, not a generic audio URL. It must be connected to an upstream Suno node (Generate, Cover, etc.).
• To extend audio from non-Suno sources, use the Suno Upload Extend node instead.
• The Extension Prompt supports up to 5000 characters, allowing for very detailed continuation instructions.
• When Use Default Parameters is off, Style Weight, Weirdness, and Audio Weight become active controls.
