In JJazzLab "rhythm" usually means a music style, like pop or bossa-nova.

What is JJazzLab?

🎵 With JJazzLab you quickly create backing tracks for any song, even complex ones. 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.

🎷 JJazzLab is designed to make non-boring backing tracks, backing tracks with variety, rhythmic accents and dynamics. You can start a solo slowly and gradually build up the atmosphere!

💻 JJazzLab is open-source with an open architecture: developers can easily add new features and new music generation capabilities.

Getting started

Install and run JJazzLab, then :

  1. Load an example song file : menu File/Open Songs... and select ExampleFiles/BluesMinor.sng

  2. Press the Play button : you should hear the backing track -if not, check the Midi Out device in menu Tools/Options (Preferences on Mac)

  3. Start editing the song using the editors and hear how it impacts the generated backing track.

If you prefer to quickly create a new backing track from scratch, check out this video:
