Suno Add Vocals

Add AI-generated vocals to an existing instrumental track.

Overview

Suno Add Vocals takes an existing Suno audio track (typically an instrumental) and generates vocal content to accompany it. The node requires a Suno Task ID and Audio ID from an upstream node. Model selection is limited to V5 and V4.5 Plus, which are the versions that support this operation.

Configuration

Field	Type	Default	Description
Model	enum	"V5"	Suno model version: V5 or V4_5PLUS.
Task ID	string	""	Suno task ID from an upstream Suno node (resolved automatically).
Audio ID	string	""	Suno audio ID from an upstream Suno node (resolved automatically).

Inputs & Outputs

• Inputs: audio – Suno task ID and audio ID from an upstream Suno node
• Outputs: audio – audio URL with added vocals

  Best Practices

• Use this after generating an instrumental track (via Suno Generate with the Instrumental toggle on) to add vocals.
• V5 typically produces more natural and expressive vocal performances.
• For best results, ensure the source instrumental has a clear melodic structure the AI can follow.
• Combine with Suno Separate to swap vocals: extract instrumentals from one track, then add new vocals.
• The AI will generate lyrics and melody automatically based on the instrumental’s characteristics.

Common Use Cases

• Adding vocals to an instrumental-only Suno generation.
• Re-vocaling a track after separating and discarding the original vocals.
• Creating vocal versions of backing tracks or beats.
• Building remix workflows: Suno Generate (instrumental) -> Suno Add Vocals.
• Layering new vocal performances onto existing instrumental arrangements.

Tips

• Only two model versions are available for this operation: V5 and V4.5 Plus.
• Task ID and Audio ID are resolved automatically from the upstream Suno node connection.
• This node is the counterpart to Suno Add Instrumental – one adds vocals, the other adds instrumentals.
• The generated vocals (lyrics and melody) are determined by the AI based on the instrumental input. You cannot specify custom lyrics with this node.
• The source track must originate from a Suno node. For non-Suno audio, consider Upload Extend or other workflows.
