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

The JJazzLab UI (available in several languages thanks to the JJazzLab community):

JJazzLab embeds its own customized software synth based on FluidSynth. For even better sounds, just connect JJazzLab to VST plugins via a virtual Midi cable and a VST host.

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.

Check out the demos of the JJazzLab YouTube channel.

JJazzLab is based on the Apache Netbeans Platform 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".

The JJazzLab Toolkit 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.
