# JJazzLab

JJazzLab is a complete and open application dedicated to backing tracks generation. You type in chord symbols, select a rhythm (music style), then the application generates a complete backing track with drums, bass, guitar, piano, strings, etc. 

The objective is to generate **interesting backing tracks**, i.e tracks which are: 
- realistic
- non-boring (with variations and dynamics)
- easily customizable, even for complex songs

JJazzLab embeds its own customized software synth based on [FluidSynth](https://www.fluidsynth.org/). For even better sounds, just connect JJazzLab to VST plugins via a virtual Midi cable and a VST host.

## Community

JJazzLab has 35.000+ users from 90+ countries. It’s a jam buddy to have fun practicing at home or learn new stuff. It’s also a great tool for teaching or early-stage composing.

## An open architecture

JJazzLab is based on the [Apache Netbeans Platform](https://netbeans.apache.org/front/main/index.html) which provides a reliable and extensible application architecture via plugins.

Developers can easily add music generation capabilities or try new ideas, without taking care of all the "plumbing".

## JJazzLab Toolkit for developers

The [JJazzLab Toolkit](https://github.com/jjazzboss/JJazzLabToolkit)  is a single standalone jar (all dependencies included) which contains the JJazzLab core (no GUI).

It makes it easy to experiment with JJazzLab models and algorithms, or create your own plugins.
