JJazzLab 3.1 release notes
Toggle compact/full view in song structure editor
Use the button (or press V) to switch between compact or full view. Adjust the visible rhythm parameters in the compact view settings. These settings are saved with the song.
Simplified usage of adapted rhythms
If you change the time signature of a section, an adapted rhythm is automatically created with the new time signature. If you don’t want this adapted rhythm, just select a different rhythm.
Many bug fixes
See list below.

JJazzLab 3.0 release notes
Dark Theme with improved graphics
Light Theme is gone, it was too much work to maintain 2 themes.
Auto-update of the playing backing track
When a backing track is playing, changing chord symbols or rhythm parameters (e.g. change variation, add a drums fill, etc.) will immediatly update the backing track (no more need to press Stop then Play again). You can turn this off via the toggle button shown below.
Improved rhythm selection dialog
You can now preview the different variations of a rhythm, permanently delete a rhythm file, or open the directory of a rhythm in a file explorer.
New Drums Transform rhythm parameter
For example, in just 1 click you can transform hi-hat notes into ride cymbal notes in the verses of your song, or add percussions in the chorus parts, etc.
New Custom Phrase rhythm parameter
For example use your own bass line for the chorus song part. To add notes to your custom phrase, drag & drop a Midi file or open an external Midi editor from JJazzLab (you can configure one in the General panel of the Options, for Windows I recommend MidiEditor, a lightweight and free software).
Copy/Paste rhythm parameter values
For example apply your custom percussion phrase to other song parts.
Jump to previous/next song part
Use F1/F2 from the keyboard. These commands can also be used remotely via Midi, see “Midi input and Midi remote commands” below.
View notes of the selected chord symbol, or from a playing track.
JJazzLab generates guidelines in your chord leadsheet for selected improvisation exercises. JJazzLab 3.0 proposes 3 exercises from the great book “How To Improvise” by Hal Crook. Others will be added in future versions (your inputs are welcome!).
Midi input and remote Midi commands
You can trigger music control actions (play, stop, …) from any Midi input sequence via Midi Learn.
(Pseudo) arranger keyboard mode
Select a song part, press the Arranger Play button and JJazzLab will recognize the chords received on Midi input and update the backing track accordingly.
IMPORTANT: This is NOT a true realtime arranger mode, it’s more for educational purpose.
Add one or more user tracks to your backing track. To add notes to the user track drag & drop a Midi file to the user rectangle area, or open an external Midi editor from JJazzLab (you can configure one in the General panel of the Options, for Windows I recommend MidiEditor, a lightweight and free software).
IMPORTANT: JJazzLab does not support Midi input recording.
Export Midi files via drag & drop from the Mix Console
You can easily export the whole backing track or just one instrument track using drag & drop from the Mix Console. This is convenient when working with a DAW (Cubase, Reaper, etc.) with JJazzLab.
Adjust audio latency
Sometimes audio notes (the notes you hear) lag a bit behind the user interface changes. This depends on your hardware configuration. You can now fix this by adjusting the audio latency from the Output Synth Editor.
- New keyboard shortcut Shift-SPACE to stop a song (SPACE is play/pause)
