Generate studio-quality music 15× faster with breakthrough diffusion technology.Who it's for: creators who want this pipeline in ComfyUI without assembling nodes from scratch. Not for: one-click results with zero tuning — you still choose inputs, prompts, and settings.<h3 id="open-preloaded-workflow-on-runcomfy">Open preloaded workflow on RunComfy</h3><a target="_blank" rel="ugc" href="https://www.runcomfy.com/comfyui-workflows/ace-step-music-generation-model-in-comfyui-ai-audio-creation?utm_source=civitai&amp;utm_medium=referral">Open preloaded workflow on RunComfy (browser)</a>Why RunComfy first - Fewer missing-node surprises — run the graph in a managed environment before you mirror it locally. - Quick GPU tryout — useful if your local VRAM or install time is the bottleneck. - Matches the published JSON — the zip follows the same runnable workflow you can open on RunComfy.When downloading for local ComfyUI makes sense — you want full control over models on disk, batch scripting, or offline runs.How to use (local ComfyUI) 1. Load inputs (images/video/audio) in the marked loader nodes. 2. Set prompts, resolution, and seeds; start with a short test run. 3. Export from the Save / Write nodes shown in the graph.Expectations — First run may pull large weights; cloud runs may require a free RunComfy account.<hr /><h3 id="overview">Overview</h3>ACE-Step is a breakthrough open-source foundation model for music generation that bridges the gap between generation speed and musical quality. By integrating diffusion-based generation with Sana's Deep Compression AutoEncoder and a lightweight linear transformer, it synthesizes up to 4 minutes of high-quality music in just 20 seconds—15× faster than LLM-based alternatives. The model excels at maintaining musical coherence while offering advanced control over lyrics, voice cloning, and remixing capabilities.Important nodes:<ul><li><code>TextEncodeAceStepAudio</code></li><li><code>KSampler</code></li><li><code>EmptyAceStepLatentAudio</code></li><li><code>SaveAudio</code></li><li><code>lyrics_strength</code></li><li><code>control_after_generate</code></li><li><code>filename_prefix</code></li></ul><h3 id="notes">Notes</h3>ACE-Step Music Generation Model in ComfyUI | AI Audio Creation — see <a target="_blank" rel="ugc" href="https://www.runcomfy.com/comfyui-workflows/ace-step-music-generation-model-in-comfyui-ai-audio-creation?utm_source=civitai&amp;utm_medium=referral">RunComfy page</a> for the latest node requirements.
