⚡ Quick Start

🎯 Pinokio - 1-Click Install (Recommended for All Users!)

The easiest way to get ACE-Step UI up and running on any platform — no terminal, no manual setup:

Pinokio handles everything automatically: Python, Node.js, dependencies, model downloads, and launching. Just click install and start making music.

🪟 Windows - One-Click Start (Easiest!)

cd ace-step-ui
start-all.bat

That's it! This starts everything: API + Backend + Frontend in one command.

Note: By default, it looks for ACE-Step in ..\ACE-Step-1.5.

If yours is elsewhere, set ACESTEP_PATH first:

> set ACESTEP_PATH=C:\path\to\ACE-Step-1.5


> start-all.bat
>

🪟 Windows - Manual Start

REM 1. Start ACE-Step Gradio (with API endpoints) cd C:\ACE-Step-1.5 python_embeded\python -m acestep --port 8001 --enable-api --backend pt --server-name 127.0.0.1

REM 2. Start ACE-Step UI (in another terminal) cd ace-step-ui start.bat

Linux / macOS - One-Click Start (Easiest!)

cd ace-step-ui
./start-all.sh

That's it! This starts everything: Gradio + Backend + Frontend in one command.

Note: By default, it looks for ACE-Step in ../ACE-Step-1.5.

If yours is elsewhere, set ACESTEP_PATH first:

> export ACESTEP_PATH=/path/to/ACE-Step-1.5


> ./start-all.sh
>

To stop: ./stop-all.sh

Linux / macOS - Manual Start

# 1. Start ACE-Step Gradio with API (in ACE-Step-1.5 directory)
cd /path/to/ACE-Step-1.5
uv run acestep --port 8001 --enable-api --backend pt --server-name 127.0.0.1

| Access | URL | |--------|-----| | Local | http://localhost:3000 | | LAN (other devices) | http://YOUR_IP:3000 |

⚙️ Configuration

Edit server/.env:

# Server
PORT=3001
ACE-Step Gradio URL (must match --port used when starting ACE-Step)
ACESTEPAPIURL=http://localhost:8001
Database (local-first, no cloud)
DATABASE_PATH=./data/acestep.db
Optional: Pexels API for video backgrounds

🎼 Generation Modes

Simple Mode

Just describe what you want. ACE-Step handles the rest.

"An upbeat pop song about summer adventures with catchy hooks"

Custom Mode

Full control over every parameter:

| Parameter | Description | |-----------|-------------| | Lyrics | Full lyrics with [Verse], [Chorus] tags | | Style | Genre, mood, instruments, tempo | | Duration | 30-240 seconds | | BPM | 60-200 beats per minute | | Key | Musical key (C major, A minor, etc.) |

AI Enhance & Thinking Mode

| Mode | What it does | Speed impact | |------|-------------|--------------| | AI Enhance OFF | Sends your style tags directly to the model | Fastest | | AI Enhance ON | LLM enriches your tags into a detailed caption and generates proper BPM, key, time signature | +10-20s | | Thinking Mode | Full LLM reasoning with audio code generation | Slowest, best quality |

Tip: If your genre tags (e.g. "pop, rock") produce ballad-like output, turn on AI Enhance for much better genre accuracy. No extra VRAM needed — the LLM runs on CPU with the PT backend.

Batch Size & Bulk Generation

| Setting | Description | |---------|-------------| | Batch Size | Number of variations generated per job (1-4). Default is 1 for broad GPU compatibility. Higher values generate more variations but use more VRAM. 8GB GPU users should keep this at 1. | | Bulk Generate | Queue multiple independent generation jobs (1-10). Each job runs sequentially, so this is safe for any GPU. | | LM Backend | Choose between PT (~1.6 GB VRAM) and VLLM (~9.2 GB VRAM). PT is the default and works on most GPUs. |

Tip: Both batch size and bulk count are remembered in your browser — set them once and they stick for future sessions.

🔧 Built-in Tools

| Tool | Description | |------|-------------| | 🎚️ Audio Editor | Cut, trim, fade, and apply effects | | 🎤 Stem Extraction | Separate vocals, drums, bass, other | | 🎬 Video Generator | Create music videos with stock footage | | 🎨 Album Art | Auto-generated gradient covers |

🐛 Troubleshooting

| Issue | Solution | |-------|----------| | ACE-Step not reachable | Ensure Gradio server is running with --enable-api flag (see Usage section) | | CUDA out of memory | Use --backend pt (default), set batch size to 1, reduce duration, or disable Thinking Mode | | 4GB GPU - Out of memory | Use PT backend (default), batch size 1, and keep Thinking Mode OFF. LLM features require 12GB+ | | Genre always sounds like ballad | Enable AI Enhance toggle in the Style section — it enriches your tags with proper metadata | | AttributeError: 'NoneType' | Update to latest ACE-Step-1.5 (fix merged in PR #109) | | Songs show 0:00 duration | Install FFmpeg: sudo apt install ffmpeg (Linux) or download from ffmpeg.org (Windows) | | LAN access not working | Check firewall allows ports 3000 and 3001 |
