JJazzLab lets you make awesome-sounding backing tracks in just a few minutes.
- Much better sounds thanks to a new high-quality soundfont (>300MB!)
- Better rendering of Yamaha styles (full SFF1 & SFF2 format support)
- 300 embedded rhythms, plus access to thousands of Yamaha style files
Of course it's still 100% free and its relying framework is 100% open-source.
