Impro-Visor® is a music notation tool for producing monophonic lead sheets, specifically intended to help the improviser. Chord symbols are used to generate backing tracks automatically. Improvisation advice exists in the form of note coloration, database of licks, and automatic lick generation from grammars. Grammars can be learned automatically from transcriptions. Styles can be edited and created by the user. Other features include generation of roadmaps for understanding keys and idiomatic chord progressions, chord voicing keyboard, MIDI and MusicXML export. See http://www.cs.hmc.edu/~keller/jazz/improvisor for general information, including tutorials. Support and additional resources are through the user group https://groups.yahoo.com/neo/groups/impro-visor/info. The most recent source code, since summer of 2015, is housed here: https://github.com/Impro-Visor/Impro-Visor This started when SourceForge was down for over one week during an active development period.

http://blackdiamond-fmodex.freeforums.net/ BlackDiamond (formerly Crazy Machine) is a project I neglected for years until I got back into making music. The package comes with free VST plugins (gonna hunt for some more) and samples, and soon to be introduced (If I can figure out the programming ms timelines) some point in time perfect sequencer sample mixer playback thingamagiggy we are now back in full armor trying to create the wildest dreams of software working on BlackDiamond (form. crazy machine). Works with DSOUND,ASIO,ALSA AND MORE PLUS AUTODETECT.

CLEF is a Max-based modular environment for composition and performance of live electronics, developed at CIRMMT/McGill University.

 CLEF follows structural design concepts and allows users to rapidly create digital signal processing topologies and control data taking advantage of the provided infrastructure and feature set. 
 CLEF separates domain model from data access layer and user interface, relying on dedicated technologies: OpenSoundControl for data access, Max dictionaries for module description and pattr for storage management. CLEF is implemented natively on top of Max and does not require external installers, libraries or compiled code. This makes CLEF portable, compatible, and straightforward to mix and merge with your favourite patches. CLEF projects can be built into collectives or applications for easy distribution. © 2009-2014 Marlon Schumacher. All Rights Reserved.

Automatic music notation application for musicians and composers.

Mutabor is a Program that allows performing and composing microtonal music using a normal MIDI keybord. But it's powerful description language is intended to allow permanent retunings and tuning logics in to describ, what's actually goes on.

OMK are several small projects that can be glued together to build custom music controllers based on both free hard- and software. Our most prominent one is the Chimaera, a polymagnetophonic theremin offering an unprecedented expressive and dynamic play.
