What is JJazzLab?

JJazzLab is a free Midi-based application which automatically generates backing tracks (a musical accompaniment) for any song. It’s a jam buddy to have fun improvising, learn new stuff or just practice your instrument. It’s also a great tool for teachers.

Unique features:

  • Dynamic backing tracks: start a solo slowly and gradually build up the atmosphere
  • Rhythm accents to spice up your arrangement
  • Access to thousands of free Yamaha styles on the web
  • Built on JJazzLab-X, a pluggable and open-source platform
