Key Features

NetBeans Platform Architecture

JJazzLab is built on the Apache NetBeans Platform, which provides:

• Modular plugin architecture
• Robust UI framework
• Lifecycle management
• Settings and preferences system
• Update center capabilities

Main Components

Core Modules (29 modules)

• Harmony - Chord progression and harmony analysis
• Midi - MIDI file I/O and manipulation
• Rhythm - Rhythm patterns and generation
• Song - Song structure and management
• MusicControl - Playback control
• OutputSynth - MIDI output and synthesis
• And many more...

Application Modules (37 modules)

• MixConsole - Audio mixing interface
• PianoRoll - Piano roll editor
• CL_Editor - Chord lead sheet editor
• SS_Editor - Song structure editor
• Score - Musical score display
• And many more...

Plugins (3 modules)

• YamJJazz - Yamaha style file support
• JJSwing - Intelligent swing rhythm generator
• FluidSynthEmbeddedSynth - Built-in software synthesizer

Development Workflow

Making Changes

1. Edit source files in the relevant module
2. Rebuild: cd JJazzLab && mvn install -DskipTests
3. Test changes

Adding New Features

1. Create or modify modules in core/, app/, or plugins/
2. Update parent pom.xml if adding new modules
3. Follow NetBeans Platform module conventions
4. Add tests in src/test/

Running Locally

Note: This is a desktop GUI application. In the dev container (headless environment), you can:

• Build and test the code ✅
• Run unit tests ✅
• Package the application ✅
• Generate installers ✅

To actually run the GUI, you would need:

• X11 forwarding configured
• Or run on a local machine with display
• Or create platform-specific installers and test on target OS

Next Steps

For Development

1. Set up IDE integration - Import as Maven project into VS Code, IntelliJ, or NetBeans
2. Explore the codebase - Check out BUILD_AND_RUN.md for detailed info
3. Read the docs - Visit https://jjazzlab.gitbook.io/developer-guide/

For Deployment

1. Build installers: mvn nbm:build-installers
2. Test on target platforms: Windows, Linux, macOS
3. Package with custom branding if needed

For Contributing

1. Create feature branch
2. Make changes and test
3. Submit PR to upstream (if contributing back)

Useful Commands

# Quick rebuild (after changes)
