DemoApp

This small project demonstrates how to use the JJazzLab Toolkit.

What ToolkitDemoApp.java does:

• try to set up FluidSynth as output synth, or fall back to the default java synth (LOW QUALITY!)
• play test notes
• try to load the song file defined by variable PATH_TO_SNG_FILE, or create a new song
• modify the song
• generate the backing track for the song
• play the song
• export the song to Midi
• export the song to audio (only if FluidSynth is the output synth)

Fluidsynth setup

For FluidSynth to work you need to:

• download and copy JJazzLab-SoundFont.sf2 into this project root directory (next to this README)
• for Linux or MacOS: FluidSynth (>=2.2.0) must have been previously installed on your system

Compile

mvn clean compile

Run

mvn exec:exec

Sample program output

$ cd demo
$ mvn exec:exec
