On MacOS the Options are accessed via the main menu JJazzLab/Preferences.
Select all the chord symbols (right-click menu Select all the chord symbols)
Use the mouse-wheel, or right-click menu Transpose
Yes, but not directly because JJazzLab can not host VST plugins.
Install a virtual midi device and a VST Host software on your computer. You'll find on the web free applications for Windows, Linux and Mac. For example use loopMIDI (we recommend to disable its feedback detection in the Advanced settings) and SoundBridge on Windows.
In JJazzLab, go to Midi options and set the Midi out device to loopMIDI
In your VST Host software, set the Midi in device to loopMidi and make sure the VST Host and the VST plugins are configured so that all Midi channels (1-16) are received.
Play a song in JJazzLab: you should hear the VST instruments
If you don't want to select the VST sounds directly from JJazzLab, you might want to Disable all Midi parameters from the Midi menu in the Mix Console.
From JJazzLab 4, just use menu File/Export to audio -this requires FluidSynth to be the output synth. If you select the option "Separate tracks", one audio file will be generated per track.
You need to reset all JJazzLab user settings (uninstall/re-install is not enough).
The simple way: menu Tools/Options/Advanced, button Reset all user settings.
The hard way: find the location of your Netbeans user dir in menu Help/About/System Information, exit JJazzLab then delete the Netbeans user dir.
Yes. When first prompted by the JJazzLab installer, select "Install only for me", then select an installation directory where you have write access (in My Documents for example).
From JJazzLab 4, the application embeds a ready-to-use software synth (FluidSynth) optimally configured for JJazzLab, with decent sounds.
JJazzLab can drive your keyboard to benefit from its optimized sounds.
Connect your keyboard via Midi
Go to the Midi Out tab of Options/Preferences
Select the Midi output connected to your synth
In the Output Synth part, select Add synth from file..., and choose YamahaRefSynth.ins.
In the JJazzLab installation directory, edit the file etc/jjazzlab.conf and add --fontsize 16 (16 or any other value, default is 11) in the default_options variable, you should end up with something like this:
default_options="--branding jjazzlab -J-Djjazzlab.version=2.2.0 -J-Dplugin.manager.check.new.plugins=true -J-Dplugin.manager.check.interval=EVERY_DAY --fontsize 16"
Restart JJazzLab. All menus should look bigger now.
This won't solve everything though, as some editor fonts do not depend on this setting. But you can tweak some of them using menu Tools/Options/Theme. Check each item in the list and if there is a font defined, change it to make it bigger. The user settings are automatically saved, so you need to do this only once.
You can pass one or more .sng file names on the command line, JJazzLab will open them upon start.
We need the following information in order to help you:
Provide the content of the log file
Describe what does not work as expected
Describe the sequence of actions that caused the issue
To get the log file content:
After the problem has occured, go to menu Tools/Options/Advanced
Click on Show Log Window
Copy & paste the full content of this window in your bug report
If for some reason the above does not work:
Go to menu Help/About and find the location of your Netbeans user dir. For ex. on Windows C:\Users\MyName\AppData\Roaming\jjazzlab\2.2 For ex. on Linux /home/MyName/.jjazzlab/2.2
Open an explorer, go to this directory then to the var/log subdirectory
The last log file is messages.log, the previous one is messages.log.1, the before previous is messages.log.2, etc.
Find the relevant log file and send it with your bug report
If you can't find the Netbeans user dir., make sure your explorer shows the hidden files (e.g. the AppData directory is usually hidden on Windows)
To get even better sounds, you'll need to connect JJazzLab to a hardware synth or to via Midi.
There is a free version of Halion Sonic SE from Steinberg which can be used with JJazzLab to get really good sounding backing tracks, more info on the .
