About this application

JJazzLab is a desktop application designed to generate backing tracks for musical compositions. Users input chord progressions and specify rhythm styles, and the software computes accompanying tracks containing drums, bass, piano, and guitar parts. The generated audio can be played back using internal MIDI sounds or routed to external software instruments and hardware synthesizers via MIDI connections.

The application functions as a tool for musicians and students who need rhythm sections for practice or composition. It includes a variety of built-in rhythm patterns and allows customization of tempo, song structure, and instrument arrangements. Users can also export the resulting musical data as standard MIDI files for further editing in external digital audio workstations. This release is packaged specifically for Linux operating systems under the GNU Lesser General Public License.
