jMusic

"jMusic is a project designed to provide composers and software developers with a library of compositional and audio processing tools. It provides a solid framework for computer-assisted composition in Java™, and is also used for generative music, instrument building, interactive performance, and music analysis. jMusic supports musicians with its familiar music data structure based upon note/sound events, and provides methods for organising, manipulating and analysing that musical data. jMusic scores can be rendered as MIDI or audio files for storage and later processing or playback in real-time. jMusic can read and write MIDI files, audio files, XML files, and its own .jm files; there is real-time support for JavaSound, QuickTime and MIDIShare. 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. In a spirit of mutual collaboration, jMusic is provided free and is an open source project. jMusic is 100% Java and works on Windows, Mac OS, Linux, BSD, Solaris, or any other platform with Java support."

VMM-R

"VMM-R (pronounced "Vimmer") is a software MIDI sequencer and recorder. It is heavily based upon a hardware sequencer, known as the Alesis MMT-8.

VMM-R provides an affordable (free) alternative to expensive professional MIDI sequencing equipment. It runs on an ordinary home PC, requiring only Windows XP and a standard sound card. It is also intended to be suited to the music professional, able to be used for live performance on stage.

For the professional, VMM-R can communciate with any device that attaches to the MIDI port of the sound card. Such devices include synthesizers, musical keyboards, and even other sequencers (including the original MMT-8)."
