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 (required). Inherited from the connected Suno node’s selected track — the panel shows “Inherited from Suno Generate: <id>” under the field, so nothing needs pasting; switch tracks on the source node and Extend follows. A manual value applies only without a connection.
Continue From	number (seconds)	0	Timestamp in seconds where the extension begins. Must be greater than 0; leave it at 0 (or empty) and the node extends the track using Suno’s own parameters instead of the custom ones.
Extension Prompt	string	""	Prompt describing the desired continuation. Max length is per-version (5000 for V6 / V4.5+ / V5, 3000 for V4); longer input is truncated rather than rejected.
Model	enum	"V6"	Suno model version: V6 (greater musical expression, more natural vocals, richer details), V6_WILD (bolder, more distinctive, less predictable), V6_MINI (lightweight and fast), V5_5, V5, V4_5PLUS, V4_5ALL, V4_5, V4.
Title	string (max 80)	""	Title for the extended track.
Style	string (max 1000)	""	Genre and style tags for the extension. Max 1000 for V6 / V4.5+ / V5, 200 for V4.
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, the extension uses your own Style, Title, Negative Style, and Continue From instead of Suno’s defaults; when false, Suno applies its own default extension parameters (the same fallback that happens when Continue From is left at 0).
promptPrefix / promptSuffix	text	–	Optional pre/post text wrapped around the prompt at run time (settings panel → Pre & post text; hidden from app users; captured by presets). See Prompt pre & post text.

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. It must be greater than 0 and less than the track’s length; leaving it at 0 falls back to Suno’s default extension parameters (Style, Title and Negative Style are then ignored).
• Use the Extension Prompt to describe the new section (e.g., “build to an epic chorus” or “fade out with ambient pads”).
• Turn Use Default Parameters on when you need control over style weight and weirdness; leave it off to let Suno apply its own defaults for the extension.
• 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’s max length is per-version (5000 for V6 / V4.5+ / V5, 3000 for V4); longer input is truncated rather than rejected.
• Style Weight, Weirdness, and Audio Weight are only active controls when Use Default Parameters is set to true; turn it off to let Suno apply its own defaults instead.
