Java API for music programming

 JFugue is a Java API for music programming that does not require the
 programmer to be aware of all the complexities of MIDI. The music can
 be synthetized from strings that describe its notes, chords,
 instruments, etc., or can be generated in real-time in many different
 ways.
 .
 JFugue supports playing music in real time as well as saving it to
 MIDI files or send it to MIDI devices.
