  • Use chord anticipations and rhythmic accents to spice up the arrangement.
  • JJazzLab can read Yamaha style files. It also introduces new extension files for even more style variations.
  • Type in a few chord symbols, pick up a rhythm, and press start, it’s a matter of seconds. Need more? Introduce rhythm and intensity variations, custom bass phrases, etc.
  • Leverage the JJazzLab open-source code to add features and new music generation capabilities via plugins.
