JJazzLab-X is a Midi-based framework dedicated to backing tracks generation -some people talk about "play-along songs" or “auto-accompaniment applications”. You type in chord symbols, select a rhythm, then the application generates a complete backing track with drums, bass, guitar, piano, strings, etc.

The ultimate objective is to develop a jam buddy able to quickly generate intelligent and interesting backing tracks: realistic and non-boring backing tracks which you can easily adjust to song specificities.
