Download

Consult the online doc if you need detailed INSTALLATION INSTRUCTIONS -this is strongly recommended for Linux.

Windows

JJazzLab-4.1.2-Win64-Setup.exe     md5sum: fceb248a7c50a8d6c0a6328c0f04acdf

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_4.1.2-1_amd64.deb      md5sum: 6baae25c17b4b5ec6cfe72726e6044ad

sudo apt-get install ./jjazzlab_4.1.2-1_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-4.1.2-0.x86_64.rpm     md5sum: 093515c74c9418220e0c41c9857b6748

sudo zypper install ./jjazzlab-4.1.2-0.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 download and extract the tar.xz file as shown below.

JJazzLab-4.1.2-linux-x64.tar.xz      md5sum: b9bc5e3cf7455c8cf691b257a5830e59

tar -xf JJazzLab-4.1.2-linux-x64.tar.xz

Run file bin/jjazzlab to start JJazzLab.

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

Consult the INSTALLATION INSTRUCTIONS ON LINUX if required -distribution on the many Linux distros is not always easy…
