Create AI-generated music with ACE-Step 15 min

ACE-Step is an open-source music generation model developed by ACE Studio and StepFun. It generates music from lyrics and style tags, and supports editing tools such as retake, repainting, and Audio2Audio.

This guide walks you through installation, first-time generation, and basic editing workflows on Olares One.

Learning objectives

By the end of this tutorial, you will learn how to:

• Generate songs with lyrics, tags, and stylistic controls.
• Locate and download your generated audio files.
• Refine tracks by adjusting the style, editing sections, extending the song, or using a reference clip to reshape it.

Prerequisites

Before you begin, make sure you have:

• Olares One connected to a stable network.
• Sufficient disk space to download models.

Install and set up ACE-Step

With your Olares device ready, follow these steps to install ACE-Step and begin generating music.

Install ACE-Step

Follow these steps to install ACE-Step.

1. Open Market, and search for "ACE-Step".

2. Click Get, then Install.

3. Wait a few minutes for the installation to complete.

Download required models on first-time launch

Once installation finishes, open ACE-Step from Launchpad.

Olares will automatically download and install required models. A Download Manager window will appear, showing model size and download progress.

After the download completes, the ACE-Step generation interface will open automatically.

Generate your first track

Follow these steps to set your parameters and begin music generation.

Set basic parameters

• Audio Duration: Drag the slider to choose the track length (up to 240 seconds). If left at the default (-1), the audio length will be random.

• Format: Select the audio format from MP3, ogg, wav, and flac.

  MP3 recommended

  It's recommended to change the default output format to MP3. This results in much smaller file sizes, faster loading, and a better overall experience.

• Lora Name or Path: Select a LoRA model if available. Currently, only a Chinese rap LoRA is available by default.

• Tags: Enter descriptors for style, mood, rhythm, or instruments, separated by commas. For example:

  Chinese Rap, J-Pop, Anime, kawaii future bass, Female vocals, EDM, Super Fast

• Lyrics: Enter your lyrics. Use structural tags to organize the song flow:

  • [verse] for the main verse.
  • [chorus] for the chorus.
  • [bridge] for the bridge.

  Generate an instrumental-only track

  Enter the tag [instrumental] or [inst] in the Lyrics area to generate music without vocals.

Start generation

1. Click Generate when all parameters are set.
2. Once generation is complete, click the Play button to preview your track.

Save the generated music

You can save your generated music via two methods.

Audio2Audio

You can create a new track based on a reference audio clip you upload. The AI analyzes characteristics such as timbre, rhythm, and style to produce a track with a similar feel.

1. Check the box to Enable Audio2Audio.

2. Upload an existing music clip to serve as the reference.

3. Adjust the Refer audio strength slider. A higher value results in music more similar to the reference track.

4. Select a Preset style, or keep the default.

5. Set other parameters as needed.

6. Click Generate to create new music with an atmosphere similar to the reference audio.
