Open Source MinGW/MSYS2 Music Composition Software

Automatic music notation application for musicians and composers.

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.
