This course harnesses the potential of the ACE-Step V1 model inside ComfyUI, giving you a blueprint to generate original AI music for free. Whether you’re a musician, a content creator, or just curious about the bleeding edge of generative AI, you’ll find practical, hands-on guidance to take you from complete beginner to confident music maker.
The landscape of AI music is evolving rapidly. With ACE-Step V1, you’re not just experimenting,you’re stepping into a world where powerful music generation tools are open and accessible. This learning guide will walk you through every step, from installation and setup to advanced prompting, troubleshooting, and creative workflow design. Along the way, you’ll learn how to generate everything from medieval instrumentals to pop ballads with lyrics, and even create new spins on your own audio files,all within the flexible, node-based environment of ComfyUI.

Understanding ComfyUI and ACE-Step V1

Before you can create AI-generated music, you need to understand the two key players: ComfyUI and ACE-Step V1. Think of ComfyUI as the operating room where all the musical magic happens,a node-based interface that lets you visually build and manage complex AI workflows. ACE-Step V1 is the first free model designed to generate music within this environment.
ComfyUI: At its core, ComfyUI is a modular, visual interface originally built for image generation with Stable Diffusion. Over time, it’s become a Swiss Army knife for AI creativity, supporting various models, including ones for audio. You build “workflows” in ComfyUI by connecting nodes, each representing a step in the process,like loading a model, setting parameters, or saving output.
ACE-Step V1: This is the star of the show,a model specifically trained to generate music from text prompts, lyrics, or even variations of existing audio. The fact that it’s free means anyone can access the foundational tools for AI music generation, breaking down the paywall that usually exists for similar capabilities.

Example 1: Imagine building a workflow that takes a simple prompt like “epic orchestral, dramatic, cinematic” and outputs a 30-second instrumental piece, all through a few connected nodes in ComfyUI.
Example 2: Or, you could input a short audio clip of yourself humming a melody and use ACE-Step V1 to generate a rock-inspired variation of your original tune.

Setting Up: Preparing ComfyUI for AI Music Generation

To get started, you need the latest version of ComfyUI and the ACE-Step V1 model file. Proper setup is crucial to avoid technical headaches and unlock all features.
Step 1: Update ComfyUI
- The easiest method is to use the built-in ComfyUI manager. Open ComfyUI, navigate to the manager, and select the update option.
- If for any reason this fails, there’s a manual workaround: Find your ComfyUI installation folder, look for the “update” subfolder, and run the ‘update ComfyUI.bat’ file. This ensures you’re running the latest version, which is essential for compatibility with ACE-Step V1.
Step 2: Download ACE-Step V1
- Download the ACE-Step V1 model file from the official source (such as the ACE-Step V1 GitHub page or links provided in community channels).
Step 3: Organize Model Files
- Place the ACE-Step V1 model checkpoint file in the “checkpoints” folder of your ComfyUI models directory. This is where ComfyUI looks for available models.
Step 4: Access Free Workflows
- Complete AI Training shares ready-made workflows for ComfyUI users on their Discord server. These include setups for text-to-instrumental, text-to-music with lyrics, and music-to-music generation.

Example 1: You attempt to update via the manager, but it fails. You locate the ‘update Comfy UI.bat’ file in your “update” folder, run it, and successfully update the software.
Example 2: After placing the ACE-Step V1 checkpoint in the right folder, you join the Discord community and download a workflow for lyric-based music generation, saving you hours of configuration.

Tips:
- Always back up your ComfyUI folder before major updates.
- Keep your models and checkpoints organized to avoid confusion as you experiment with different workflows.

The ComfyUI Workflow: Nodes, Models, and Output

ComfyUI uses a visual, node-based approach that lets you drag, drop, and connect building blocks to define your music generation process. This modular system is intuitive once you get the hang of it.
Nodes: Each node represents a function,loading a model, setting parameters, handling prompts, or saving output. For ACE-Step V1, the workflow often requires just a few core nodes: the model node, prompt node, sampler (K sampler), and output node.
Workflows: A workflow is a map connecting nodes in a logical sequence, defining everything from the initial input (like a text prompt) to the final output (a rendered audio file).
Output: By default, your generated music is saved in the output/audio folder in FLAC format,a lossless, high-quality audio file type.

Example 1: In the text-to-instrumental workflow, you only need the ACE-Step V1 model node, a prompt node for tags, a K sampler node, and an output node.
Example 2: For music-to-music, you add an input node to upload existing audio, which feeds into the model along with prompt tags for style variation.

Best Practices:
- Name and annotate nodes in your workflow for easy navigation.
- Save backup copies of workflows as you make changes, so you can revert if needed.

Instrumental Music Generation (Text-to-Instrumental Workflow)

Creating instrumental tracks with ACE-Step V1 is the most straightforward,and often the most successful,way to start making AI music. This workflow is designed for simplicity and speed.
Prompt Area Structure: The special prompt area for ACE-Step V1 has two main sections:

• Tags: Describe the desired style, mood, or instruments for your track. Tags are separated by commas and can include genres, adjectives, or specific instruments (e.g., “medieval, upbeat, acoustic guitar, folk, energetic”).
• Lyrics: For instrumental tracks, leave this section empty by entering square brackets []. Alternatively, you can use a shorthand like [inst] or [instrumental] as a placeholder.

K Sampler Settings:

• Steps: 50 (determines the number of refinement iterations)
• CFG: 4 (controls how closely the output follows the prompt)
• Sampler Name: rest multistep
• D noiseis: 1 (amount of noise/variation introduced in generation)

Duration: You can set how long you want your song to be. Start with 30 seconds to quickly test ideas. The recommended maximum is 4 minutes to avoid crashes or excessive processing times.
Output: Generated audio is saved to the output/audio folder in FLAC format. You can also download tracks directly from the workflow interface.

Example 1: You enter tags: “synthwave, energetic, electronic, dance” and leave the lyrics section as []. The model generates a 45-second, upbeat electronic instrumental.
Example 2: You prompt with “medieval, lute, cheerful, tavern” and get a 60-second instrumental reminiscent of fantasy RPG soundtracks.

Tips and Best Practices:
- Use clear, unambiguous tags. The more precisely you describe the style, the better the results.
- Start with shorter durations for faster iterations.
- Don’t get discouraged by variable quality; generate multiple versions and select the best.
- The model’s understanding of some genres is limited, so experiment with synonyms or combinations.

Lyric-Based Music Generation (Text-to-Music with Lyrics Workflow)

If you want to generate songs with vocals, the process is similar to creating instrumentals, but the prompt structure becomes more involved. This workflow lets ACE-Step V1 synthesize lyrics, melody, and accompaniment in one go.
Prompt Area Structure: The prompt is split into two sections:

• Tags: Guide the genre, mood, and vocal style (e.g., “pop, ballad, male vocals, emotional, piano”). Including “male vocals” or “female vocals” increases your chances of getting the desired voice, though control isn’t perfect.
• Lyrics: Use a structured format for clarity:
  • [intro]
  • First lines of lyrics
  • [verse]
  • Verse lyrics go here
  • [chorus]
  • Chorus lyrics go here
  This helps the model distinguish song sections and improves coherence.

Duration: It’s crucial to set the song long enough to fit your lyrics. If the song is too short, the vocal sections may be cut off, forcing you to adjust and experiment.
Voice Quality: Expect variability. Sometimes the vocals are clear, sometimes robotic. The model is more reliable for “male” and “female” vocals; it struggles with children’s voices and duets.

Example 1: Tags: “rock, upbeat, male vocals, electric guitar”; Lyrics: [verse] I wake up to the sunlight The city calls my name [chorus] We’re running through the night Chasing down our dreams A lively rock song is generated, with an AI male voice singing your lyrics.
Example 2: Tags: “ballad, female vocals, emotional, piano”; Lyrics: [intro] Softly falls the rain [verse] I remember yesterday [female vocals] A gentle piano ballad with a female-like voice and your custom lyrics.

Tips and Best Practices:
- Use square brackets to mark song sections.
- If you want a specific language, convert your lyrics to English letters and add a language code at the start.
- Test with different tags if initial results don’t match your intent.
- Generate several versions; pick the best take, as quality varies.

Music-to-Music Generation: Transforming Existing Audio

Want to remix or reinterpret an existing song? The music-to-music workflow lets you upload any audio file and create new variations, using tags to steer the style.
Input Audio: Upload an audio file (FLAC format recommended, but other formats may work). The length of your input determines the duration of the output.
Tags: Describe the new style or characteristics you want the variation to have (e.g., “orchestral, dramatic, strings”).
D noiseis Setting: This parameter controls how much the output deviates from your original audio.

• A low D noiseis (e.g., 0.1) keeps the output similar to the input.
• A higher D noiseis (e.g., 0.4 or above) introduces more variation, making the result less recognizable but more creative.
• Start experimenting at 0.4 for a good balance, then adjust based on your needs.

Output: The generated variation is saved as a new FLAC file in the output/audio folder.

Example 1: You upload a short acoustic guitar loop and set tags: “ambient, atmospheric, synths”. With D noiseis at 0.6, the result is a dreamy, electronic version of your original loop.
Example 2: You use a pop song snippet as input, tag with “jazz, saxophone, chill”, and set D noiseis to 0.3. The output is a smoother, jazzier reinterpretation of your song.

Tips and Best Practices:
- The more you increase D noiseis, the more the output will depart from the original.
- For subtle remixes, keep D noiseis low.
- For radical transformations, go higher.
- The model is still learning in this area; generating many versions increases your chance of a satisfying output.

Mastering Prompt Engineering: Tags and Lyrics

The magic of ACE-Step V1 lies in how you prompt it. Crafting effective tags and lyrics is the difference between a bland, off-target song and something personal and moving.
Tags: These are your main lever for steering the genre, instrumentation, energy, and mood of your music. Good tags are descriptive and concise.

• Separate tags with commas.
• Include genres, moods, instruments, and vocal descriptors.

Examples of Tags:

• “lofi, chill, instrumental, soft piano, relaxing”
• “symphonic, epic, male vocals, cinematic, dramatic”

Lyrics: For vocal music, structure matters. Use brackets to mark sections ([verse], [chorus], [bridge]), and keep lines clear and simple.

Example 1: For an energetic dance track: Tags: “EDM, upbeat, dance, synth, female vocals”
Example 2: For a moody instrumental: Tags: “ambient, downtempo, electronic, dark, instrumental”

Best Practices:
- Don’t overload the tag list; 3-6 tags is a sweet spot.
- For non-English lyrics, transliterate into English letters and add the language code.
- If you want to experiment, swap out one tag at a time to see how it affects the output.
- Not all styles are equally supported; if the model doesn’t understand “African drums,” try “tribal percussion” or “ethnic rhythm.”

Leveraging External Tools: Using ChatGPT for Prompt Creation

Writing song lyrics and picking the right tags can be a creative bottleneck. The tutorial recommends using large language models like ChatGPT to streamline this process.
How to Use ChatGPT with ACE-Step V1:

• Ask ChatGPT to generate a list of music tags based on your desired style and mood (“Give me 5 descriptive tags for an energetic, orchestral track inspired by movie soundtracks.”)
• Prompt ChatGPT for lyrics in a specific structure (“Write a short pop song about summer love, with [verse], [chorus], and [bridge] sections.”)

Example 1: You type into ChatGPT: “Write 8 tags for an epic fantasy soundtrack.” It replies: “orchestral, epic, adventure, cinematic, strings, choir, dramatic, fantasy.”
Example 2: You ask: “Write lyrics for a rock ballad about hope, with an intro, verse, and chorus.” ChatGPT provides a neatly formatted set of lyrics you can paste directly into the workflow.

Best Practices:
- Refine ChatGPT’s output to fit within the model’s input limits.
- Always check and edit for clarity and appropriateness.
- Use ChatGPT’s ability to brainstorm alternative tags if your initial attempts don’t yield strong results.
- Store successful tag/lyric combinations in a document for future reuse.

Advanced Settings and Optimization

To get the most from ACE-Step V1, you need to understand the parameters that influence the final output. These include steps, CFG, sampler type, seed, and D noiseis.
Steps: More steps mean greater refinement, but longer processing time. 50 is a good starting point.
CFG (Classifier Free Guidance): Higher values force the model to stick closer to your prompt; lower values allow more creativity.
Sampler Name: “rest multistep” is recommended for stable results.
Seed: The seed is a random number used to initialize generation. Fixing the seed lets you test parameter tweaks and compare results. Varying the seed gives you different versions with the same prompt.
Duration: Be mindful of song length. The model is faster with short tracks; longer durations sometimes fail or sound stretched.
D noiseis: Especially critical in music-to-music workflows; tune carefully to balance similarity vs. creativity.

Example 1: You set seed to 42 and experiment with different tags, keeping all else constant to compare outputs.
Example 2: You run five generations with different seeds, all with the same prompt, and pick your favorite.

Tips:
- Don’t be afraid to experiment with parameters,sometimes small tweaks yield big improvements.
- If output quality is low, try lowering CFG for more creative takes, or raising it for stricter adherence to your tags.
- Keep notes on settings that produce your best results for future reference.

Understanding Limitations and Workarounds

ACE-Step V1 is powerful, but it’s not magic. Knowing its limitations will help you get the best results and avoid frustration.
Areas of Strength:

• Instrumental generation is fast and can produce surprisingly good tracks.
• Text-to-music with lyrics works well for basic male/female vocals and standard genres.
• Music-to-music can create interesting remixes, though it’s less predictable.

Current Limitations:

• Not all musical styles are well supported (e.g., “epic music,” “African drums”).
• Vocal quality can be inconsistent; sometimes robotic, especially with complex lyrics or non-standard voices.
• Duets and children’s voices are difficult to achieve.
• Model sometimes ignores tags or misinterprets prompts.
• Multiple generations are usually required to find a standout track.
• Long song durations increase the risk of errors or low-quality output.
• Non-English lyrics require transliteration and language code.
• Music-to-music needs more training for high-quality remixes.

Workarounds:

• For genres the model struggles with, try synonyms or combine multiple tags.
• Use ChatGPT to generate alternative tag lists and lyrics.
• Generate 5-10 versions of each idea, then curate the best.
• Keep a “favorites” folder for successful outputs to build your own AI music library.

Example 1: You want “children’s choir.” The model struggles, so you try “soft vocals, high pitch, gentle, group vocals” as tags and achieve a closer result.
Example 2: You want “African drums, energetic.” The model delivers a generic beat, so you try “tribal percussion, rhythmic, world music” and get something more interesting.

Saving, Accessing, and Using Generated Music

Once your music is generated, you’ll want to locate, save, and possibly edit or share the files.
File Location: All generated audio is saved by default in the output/audio folder of your ComfyUI setup. Files are named with a prefix and a unique identifier.
