uv run acestep --port 8001 --enable-api --backend pt --server-name 127.0.0.1
```
**Windows (Standard Installation):**
```batch
cd C:\path\to\ACE-Step-1.5
uv run acestep --port 8001 --enable-api --backend pt --server-name 127.0.0.1
```
Wait for "API endpoints enabled" before proceeding.

## 🎼 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](https://ffmpeg.org) (Windows) |
| **LAN access not working** | Check firewall allows ports 3000 and 3001 |
