JJazzLab 4.0.2 (January 7, 2024)

JJazzLab Dark JJazzLab Dark JJazzLab Spain Demo    

4.0.2 fixes many bugs from 4.0.1, upgrade is highly recommended.

New features 4.0

  • FluidSynth, the JJazzLab builtin synth
    JJazzLab 4 now embeds a ready-to-use builtin synth based on FluidSynth.

  • Midi editor
    A full-featured “piano-roll” editor to edit user tracks or customize a rhythm phrase. Midi file drag & drop is supported.

  • Bar annotations
    Add lyrics or notes to any measure.

  • Easy reader window
    Easily follow which chords (and lyrics) are currently playing, even with complex songs.

  • Customize sections and chords colors
    E.g. make this C7M red to remember to try the Lydian scale on it.

  • Export to audio
    Easily create a .mp3 or .wav file for the current song (or for each individual track).

  • And many more…
    New “NC” chord which stops music, new score notation for chord inspector, new light theme, import from .csv/.txt file, etc.

See the 4.0.2 release notes and the online doc for more details.

Download

Consult the online doc for more detailed installation instructions.

Windows

JJazzLab-4.0.2-win-x64-setup.exe    md5sum: 6ab44082a53451bb80a1caee3501bcea

If you get a Windows Smart Screen alert, click on More info, this will let you run the installer anyway. JJazzLab is NOT a malware! You can use md5sum to check file integrity.

When installation package is new, Windows security servers don’t have enough statistics to evaluate its “security reputation”. Alert will disappear soon, once enough people have run the software.

Mac

You must first install FluidSynth yourself (I recommend via Homebrew).

Then:

Linux Ubuntu/Debian family (x64)

Download the .deb file and install it as shown below.

jjazzlab_4.0.2-1_amd64.deb      md5sum: 774283af12aba6c1a4abd4bbe2431986

sudo apt-get install ./jjazzlab_4.0.2-1_amd64.deb    # this will also download and install fluidsynth (>=2.2.0) if required

If FluidSynth makes some “crackling” noise, make sure your Linux is optimized for audio applications.

Linux OpenSUSE family (x64)

Download the .rpm file and install it as shown below.

jjazzlab-4.0.2-0.x86_64.rpm     md5sum: 9e5b191d7cd0df0df03d240348e32786

sudo zypper install ./jjazzlab-4.0.2-0.x86_64.rpm      # this will also download and install fluidsynth (>=2.2.0) if required

If FluidSynth makes some “crackling” noise, make sure your Linux is optimized for audio applications.

Linux others (x64)

You must first install FluidSynth (>=2.2.0) yourself.

Then:

JJazzLab-4.0.2-linux-x64.tar.xz      md5sum: 88ecba4f37b15eeaa8699e334ca714c3
Extract then run file bin/jjazzlab to start JJazzLab.

If FluidSynth makes some “crackling” noise, make sure your Linux is optimized for audio applications.
