# ACE-Step Nodes for ComfyUI
Fast, high-quality music generation, "repainting", remixing, editing, extending, and more. Windows, Linux, and Mac should all be supported (not fully tested).
## 📣 Updates
[2025-05-14]⚒️:
- Support Lora, [ACE-Step-v1-chinese-rap-LoRA](https://huggingface.co/ACE-Step/ACE-Step-v1-chinese-rap-LoRA) download and place it in the `models\TTS\ACE-Step-v1-3.5B\loras` directory.
```
loras
└─ACE-Step-v1-chinese-rap-LoRA
config.json
pytorch_lora_weights.safetensors
```
- Add many delicious reference song parameters.
[2025-05-12]⚒️: Add model loader node, customizable model loading. Thank you for @[thezveroboy's](https://github.com/thezveroboy) contribution. Add `cpu_offload`, 8g of memory available, faster speed.
[2025-05-10]⚒️: Added a node for lyrics language conversion to provide multilingual support for the official [ComfyUI](https://docs.comfy.org/tutorials/audio/ace-step/ace-step-v1) ACE-Step workflow.
[2025-05-07]⚒️: Released version v1.0.0.
## Usage
- Lora:
Added a node for lyrics language conversion to provide multilingual support for the official [ComfyUI](https://docs.comfy.org/tutorials/audio/ace-step/ace-step-v1) ACE-Step workflow. Currently, ACE-Step supports 19 languages, but the following ten languages have better support:
- English
- Chinese: [zh]
- Russian: [ru]
- Spanish: [es]
- Japanese: [ja]
- German: [de]
- French: [fr]
- Portuguese: [pt]
- Italian: [it]
- Korean: [ko]
- Generation:
- "Repainting":
- Extending:
- Editing:
- Automatically generate lyrics, prompt, pause workflow, modify and then click `continue workflow` to continue workflow [example](workflow-examples/ACE-gen-automated-composition.json). The latest Gemini, Qwen3, and DeepSeek v3 are available:
## Installation
```
cd ComfyUI/custom_nodes
git clone https://github.com/billwuhao/ComfyUI_ACE-Step.git
cd ComfyUI_ACE-Step
pip install -r requirements.txt
# python_embeded
./python_embeded/python.exe -m pip install -r requirements.txt
```
## Model Download
https://huggingface.co/ACE-Step/ACE-Step-v1-3.5B
