The ACE-Step 1.5 Music Generation Workflow is designed to transform text prompts into high-quality audio songs in a matter of seconds using consumer hardware. This workflow leverages the ACE-Step model, specifically the 'acestep_v1.5_turbo.safetensors', to interpret and synthesize music based on user-provided descriptions of music style and optional lyrics. Key nodes such as the TextEncodeAceStepAudio1.5 and VAEDecodeAudio play crucial roles in encoding the text input and decoding the generated audio, respectively. The KSampler node is used for sampling the latent space, while the ModelSamplingAuraFlow node refines the audio output to ensure it meets high-quality standards.
This workflow is particularly useful due to its efficiency and the quality of audio it produces. By using nodes like ConditioningZeroOut and EmptyAceStep1.5LatentAudio, it ensures that the audio generation process remains streamlined and focused on the user's input. The inclusion of the SaveAudioMP3 node allows for easy export of the final product in a widely compatible format. This makes the workflow not only technically robust but also highly practical for users looking to quickly generate music for various applications.
API
Use this workflow from code
Every Comfy workflow is a JSON graph. The payload below is this workflow, exactly as ComfyUI runs it — fetch it from the URL, keep it in version control, or load it in ComfyUI and run it node by node.
Run it from TypeScript or Python with the Comfy SDK. The same code targets Comfy Cloud or a ComfyUI you host yourself — only the base URL changes.
// Install (beta)
npm i @comfyorg/sdk
// Run "ACE-Step 1.5 Music Generation Workflow" (TypeScript)
import { Comfy } from "@comfyorg/sdk";
const client = new Comfy({ apiKey: "comfyui-..." });
// This workflow, exported in API format (see note below)
const wf = await client.workflows.fromFile("audio_ace_step_1_5_split_api.json");
const job = await client.run(wf);
await job.getOutputs("107")[0].toFile("output.png"); // SaveAudioMP3The SDK takes a workflow in API format: open this workflow in ComfyUI and use File → Export Workflow (API).
Comfy Cloud API access requires a plan with an API key.
