# Sonilo API Node Official ComfyUI Example

> This article introduces how to use Sonilo Partner nodes for video-to-music and text-to-audio generation in ComfyUI.

Sonilo is an AI-powered video-to-music service that generates soundtracks synchronized to your footage. It analyzes visuals, pacing, and emotional cues to produce music locked to your timeline, frame by frame.

You can drive music generation directly from your ComfyUI node graphs, alongside your existing workflows.

## Highlights

* **Length, pace and emotion alignment** - Music is generated to match the exact duration, pacing, and emotional arc of your video, delivering soundtracks that feel intentionally composed for the content.
* **Instant generation** - Generate full-length, high-quality music in seconds, enabling faster iteration and a seamless creative workflow.
* **Commercial-ready usage** - All generated music includes commercial use rights, making it ready for use across professional, brand, and production environments without additional licensing complexity.

<Tip>
  To use the API nodes, you need to ensure that you are logged in properly and using a permitted network environment. Please refer to the [API Nodes Overview](/tutorials/partner-nodes/overview) section of the documentation to understand the specific requirements for using the API nodes.

  <Tabs>
    <Tab title="Portable or self deployed users">
      Make sure your ComfyUI is updated.

      * [Download ComfyUI](https://www.comfy.org/download)
      * [Update Guide](/installation/update_comfyui)

      Workflows in this guide can be found in the [Workflow Templates](/interface/features/template).
      If you can't find them in the template, your ComfyUI may be outdated. (Desktop version's update will delay sometime)

      If nodes are missing when loading a workflow, possible reasons:

      1. You are not using the latest ComfyUI version (Nightly version)
      2. Some nodes failed to import at startup
    </Tab>

    <Tab title="Desktop or Cloud users">
      * The Desktop is base on ComfyUI stable release, it will auto-update when there is a new Desktop stable release available.
      * [Cloud](https://cloud.comfy.org) will update after ComfyUI stable release.

      So, if you find any core node missing in this document, it might be because the new core nodes have not yet been released in the latest stable version. Please wait for the next stable release.
