Java internal synth
The Java runtime engine used by JJazzLab has an internal Midi synth (sometimes callled Gervill).
If you don't load a SoundFont file it will use its built-in GM sounds.
The built-in GM sounds are not good quality sounds, but it can be enough to test JJazzLab. The good thing is that no setup is required, it will work out-of-the-box.
The Java internal synth is not high-performance. When used with a large SoundFont like the JJazzLab SoundFont you may hear some dropped notes when too many notes are played.
- 2.In the JJazzLab Midi options, select the Java Internal Synth and load the JJazzLab-SoundFont.sf2
- 3.Go to the Output Synth Editor and apply the preset Java Internal Synth
If you’re on Mac OSX the Midi configuration wizard will automatically perform the same steps if you choose to use the JJazzLab SoundFont.
