Common Music (CM) is a real-time music composition system implemented in JUCE/C++ and Scheme. It generates musical output via MIDI, OSC, CLM, FOMUS and CSOUND. Its user application is called GRACE (Graphical Real-time Algorithmic Composition Environment)

Features:

• Algorithmic music composition environment
• Runs on Mac, Windows and Linux
• Real time scheduling of musical algorithms
• Two coding languages for designing algorithms: S7 Scheme and SAL (an easy-to-learn alternate)
• MIDI input/output
• CLM/Sndlib audio system built in (Scottstaedt)
• CCRMA digital audio instrument definitions built in (Scottstaedt)
• Open Sound Control input/output
• Metronomes and running algorithm redefinition for live coding
• Data visualization
• Music pattern definitions
• Fomus system built in for computing music notations (Psenicka)
