ACE-Step 1.5 Music Generation AIO is a text-to-audio ComfyUI workflow that turns style tags and lyrics into a complete song. You provide short descriptors like "modern pop, female vocal, lush synths" plus your lyrics, and the graph handles the rest—sampling, decoding, and exporting MP3—so you can audition ideas in seconds on consumer hardware. It’s organized into clear groups—Step 1: Load Model, Step 2: Duration, Step 3: Prompt—so you always know where to set the checkpoint, how long the track should be, and what the model should sing or sound like.
Under the hood, CheckpointLoaderSimple loads the ACE-Step 1.5 checkpoint (ace_step_1.5_turbo_aio.safetensors). TextEncodeAceStepAudio1.5 converts your style tags and lyrics into ACE-specific conditioning vectors. ConditioningZeroOut is used to cleanly disable unused conditioning channels (for example, when you’re not providing a secondary or negative prompt), preventing unintended bias. EmptyAceStep1.5LatentAudio creates an empty latent audio canvas for the exact duration you request. ModelSamplingAuraFlow configures the correct sampler/scheduler combination for ACE-Step 1.5, and KSampler iteratively refines the latent into a coherent track based on your prompt. VAEDecodeAudio turns the final latent into waveform audio, and SaveAudioMP3 writes the result to your ComfyUI output folder. PrimitiveNode widgets expose practical knobs like steps, CFG, seed, and seconds so you can tweak speed, quality, and reproducibility.
This setup is useful for fast songwriting demos, genre exploration, and content beds. You get precise control over duration and a repeatable workflow via the seed. The graph ships with sensible defaults so you can generate a short track quickly, then dial in higher quality by raising steps or refining style tags and lyric phrasing.
API
코드에서 이 워크플로우 사용하기
모든 Comfy 워크플로우는 JSON 그래프입니다. 아래 페이로드는 이 워크플로우 그 자체로, ComfyUI에서 실행되는 것과 동일합니다 — URL에서 가져오거나, 버전 관리에 보관하거나, ComfyUI에서 불러와 노드별로 실행할 수 있습니다.
Comfy SDK로 TypeScript 또는 Python에서 실행하세요. 동일한 코드는 Comfy Cloud 또는 직접 호스팅하는 ComfyUI 모두에 적용됩니다 — 기본 URL만 다릅니다.
// Install (beta)
npm i @comfyorg/sdk
// Run "ACE-Step 1.5 음악 생성 AIO" (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_checkpoint_api.json");
const job = await client.run(wf);
await job.getOutputs("104")[0].toFile("output.png"); // SaveAudioMP3SDK는 API 형식의 워크플로우를 사용합니다: 이 워크플로우를 ComfyUI에서 열고 파일 → 워크플로우 내보내기(API)를 사용하세요.
