Based on the JJazzLab-X open-source platform

JJazzLab relies on JJazzLab-X, the open-source platform dedicated to backing tracks generation. JJazzLab-X is designed so that third-party developers can easily extend it with new features and new rhythm generation capabilities.

A simple and powerful user interface

You want to practice your instrument on a few chords ? Type in the chord symbols, pick up a rhythm, and press start, it’s a matter of seconds. You want more variety ? Use the song structure editor to reorder sections or introduce rhythm and intensity variations.

Why jjazzlab ?

As a jazz/funk pianist I have tried most of the auto-accompaniment or backing tracks apps (Band In a Box, etc). They are good indeed and I had some fun at first, but I quickly got frustrated: I missed the intensity dynamics which help develop interesting solos. I was aware that a program will never match a real band, but I had a few ideas how to do better. That’s why I decided to start developing JJazzLab -in my spare time, so please be indulgent !
