Suno Add Instrumental

Add an AI-generated instrumental backing track to an existing vocal track.

Overview

Suno Add Instrumental takes an existing Suno audio track (typically one with isolated vocals) and generates a complementary instrumental arrangement 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 instrumental
Best Practices
Use this after Suno Separate to add a new instrumental to isolated vocals.
V5 generally produces higher quality instrumentals than V4.5 Plus for this node.
Ensure the source track has clear vocals for the best instrumental matching.
Pair with Suno Separate (vocal extraction) and then Add Instrumental for complete vocal re-arrangement workflows.
The AI will attempt to match the genre, tempo, and key of the source audio automatically.

Common Use Cases

Adding backing music to an acapella or vocal-only track.
Re-instrumenting a song after separating its original instrumental.
Creating new arrangements of existing vocal performances.
Building remix workflows: Suno Generate -> Suno Separate -> Suno Add Instrumental.
Producing alternate instrumental versions of the same vocal take.

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 Vocals – one adds instrumentals, the other adds vocals.
The source track must originate from a Suno node. For non-Suno audio, consider Upload Extend or other workflows.
