Open Source Java Music Composition Software

SoundHelix is a free versatile Java framework for algorithmic random music composition. SoundHelix can generate random songs, play them (for example, on any number of MIDI devices or MIDI-capable software synthesizers) and is highly customizable using XML configuration. SoundHelix also allows writing the generated music as MIDI files. SoundHelix produces music that is actually enjoyable to listen to.

It allows you to use JFugue-2.1 API to program music on MIDP 2.0, CLDC 1.1 compatible mobile devices. It's easy to use, like this code to play C-major scale: Player player = new Player(); player.play("C D E F G A B"); It's all based on JFugue-2.1 sources, so go to http://www.jfugue.org for more information.
