As a library of classes for generating and manipulating music and audio, jMusic provides a solid framework for computer-assisted composition in Java. jMusic supports composers by providing a music data structure based upon note/sound events, methods for analysing and working with that musical data, and the ability to render your music as real-time playback or to files for storage or later processing. jMusic can read and write MIDI files, audio files, XML files, and its own .jm files. jMusic is designed to be extendible, encouraging you to build upon its functionality by programming in Java to create your own musical compositions, tools, and instruments. jMusic is 100% Java and works on Windows, Mac OS, Linux, Solaris, or any other platform with Java support.

Additions in this release include, a new compressor audio object, better handling of frequency pitches when writing MIDI files, audio envelopes now cope with extremely short notes, addition real-time instruments are included, and a few bug fixes.
