# 🎹 MIDI Editor - Web-based Singing MIDI Editor
|
||||
|
||||
[English](README.md) | [简体中文](README_CN.md)
|
||||
|
||||
A full-featured web MIDI editor for singing voice production, similar to ACE-Studio and VOCALOID. It supports real-time drag editing of MIDI notes, lyric editing, audio waveform alignment, and importing/exporting MIDI files with lyrics.
|
||||
|
||||
  
|
||||
|
||||
## ✨ Features
|
||||
|
||||
### 🎼 Piano Roll Editing
|
||||
|
||||
- **Visual note editing**: Full range from C1 to C8 with intuitive piano keys
|
||||
- **Drag operations**:
|
||||
- Move notes: drag note blocks to adjust position and pitch
|
||||
- Resize start: drag the left edge to adjust start time
|
||||
- Resize end: drag the right edge to adjust end time
|
||||
- **Double-click to add**: Add new notes quickly in empty areas
|
||||
- **Piano key preview**: Click a key to audition the pitch
|
||||
|
||||
### 🔍 Zoom & Navigation
|
||||
|
||||
- **Horizontal zoom**
|
||||
- **Vertical zoom**
|
||||
- **Dynamic snapping**: finer snap granularity at higher zoom (min 0.01s)
|
||||
- **Auto scroll**: keep the playhead visible during playback
|
||||
|
||||
### 📝 Lyric Editing
|
||||
|
||||
- **Inline editing**: edit lyrics for each note in the side list
|
||||
- **Batch fill**: enter a string and auto-fill notes in order
|
||||
- **Fill from selection**: start batch fill from the selected note
|
||||
- **Precise fields**: edit PITCH, START, and END directly
|
||||
- **Confirm edits**: press Enter or click ✓ to confirm
|
||||
|
||||
### 🎵 Audio Alignment
|
||||
|
||||
- **Waveform display**: sync waveform with the MIDI timeline
|
||||
- **Formats**: MP3, WAV, OGG, FLAC, M4A, AAC
|
||||
- **Sync playback**: play audio and MIDI together with independent mute
|
||||
- **Click to seek**: click waveform or timeline to seek
|
||||
|
||||
### ⚠️ Overlap Detection
|
||||
|
||||
- **Visual highlight**: overlapping notes blink in red
|
||||
- **Smart tolerance**: adjacent notes (end equals next start) are not overlaps
|
||||
- **One-click fix**: remove all overlaps automatically
|
||||
- **Export warning**: warn if overlaps exist during export
|
||||
|
||||
### 📥 Import & Export
|
||||
|
||||
- **MIDI import**: parse standard MIDI and lyric metadata
|
||||
- **MIDI export**: export MIDI with lyrics
|
||||
- **Chinese support**: full UTF-8 lyrics support
|
||||
|
||||
### 🎨 UI & UX
|
||||
|
||||
- **Theme toggle**: light and dark modes
|
||||
- **Responsive layout**: adapts to window size
|
||||
- **SVG grid**: cross-browser grid rendering
|
||||
- **Status feedback**: real-time state and error tips
