## 🌟 Features

### 1. Standard ACE-Step Interface
Full-featured standard ACE-Step 1.5 GUI with all original capabilities including:
- Text-to-music generation with style control
- Variation generation
- Section repainting
- Lyric editing

### 2. Custom Timeline Workflow
Advanced timeline-based generation system:
- Generate 32-second clips with seamless blending
- Adjustable context length (0-120 seconds) for style consistency
- Master timeline with visual representation
- Extend, inpaint, and remix capabilities
- Automatic crossfading between clips

### 3. LoRA Training Studio
Complete training interface for custom models:
- Upload and preprocess audio files
- Configure training parameters
- Train specialized models for voices, instruments, or styles
- Download and reuse trained models
- Continue training from existing LoRAs

## 🚀 Quick Start

1. **First Launch**: Models download automatically from `ACE-Step/Ace-Step1.5`
2. **Standard Generation**: Use Tab 1 for traditional text-to-music
3. **Timeline Creation**: Use Tab 2 to build longer songs with consistent style
4. **Custom Training**: Use Tab 3 to create specialized models
