athenaCL description
|
Interactive command-line environment for music analysis and algorithmic composition in Csound and MIDI
athenaCL is designed to be a modular, object orientated, interactive Command-Line environment for algorithmic composition and music analysis. Scores are created in Csound as well as standard MIDI files. The software is open-source, cross-platform, and written in Python.
Musical parts are deployed as textures, layered surface-defining objects containing linked parameter objects to control pitch, tempo, rhythm, amplitude, panning, and Csound synthesis and control parameters.
The system includes an integrated library of Csound instruments. Parameter objects provide generators using stochastic, genetic, and various other algorithms. Textures can be combined, edited, cloned, and tuned with algorithmic temperament objects.
The analytic and algorithmic systems use path objects to organize and share pitch data. Based on post-tonal music theory, paths provide simultaneous representations of ordered content groups in set-class, pitch-class, and pitch space.
Paths can be modeled with the Straus voice leading system and analyzed with numerous set-class similarity measures. As a reference utility for music theory, pitch groups can be searched, analyzed, and compared with a wide variety of tools.
Here are some key features of "athenaCL":
· Advanced
· Easy to use
· Interactive command line: enter commands with arguments, or just enter the command and athenaCL will prompt the user for all necessary data
· Command history logging, and executable command history.
· Graphical displays on platforms supporting Tk or the Python Imaging Library (PIL), providing texture arrangement views, path voice leadings, and texture parameter event graphs
· Rapid creation of Csound scores and orchestras of any duration and complexity, using a built in library of instruments or your own.
· Simultaneous creation of MIDI scores, with configurable instrument and channel settings, suitable for notation or sequencing software.
· Over 20 integrated Csound instruments, all with default values and documentation
· Combine any number of musical parts or textures, controlling tempo, pitch, rhythm, amplitude, panning, and Csound parameters with over 30 dedicated, customizable parameter objects
· Parameter objects include tools for stochastic, random, chaotic, and cyclical generators; specialized objects for genetic algorithms and Xenakis sieves; linear and exponential break-point segments, masking with variable wrapping methods, accumulators
· Control panning in mono, stereo, or quadraphonic space
· Control pitch data with 12-tone pitch-class notation and partitioned pitch-space sets. Tune pitches algorithmically with microtonal resolution using temperament objects
