AC Toolbox
Author:Paul BergManipulates:MIDI, Csound score files
Description:The AC Toolbox is a Macintosh PPC application to assist the algorithmic composition of music. A legacy version for older, 68K-based computers is also available. Several models for defining musical events are included. They can be used by defining objects such as sections, shapes, masks, or note structures. It is also possible to play, plot, modify, and examine objects in a number of ways. Extensive online help is available. In addition to Midi input and output, the AC Toolbox can also produce text files suitable for use as data in other programs. In particular, score files for Csound, note list files for Common Lisp Music, and tables for MAX can be produced. An important method of creating data in the Toolbox is the use of generators. A number of generators have been included reflecting various approaches to the creation of musical material including tendency masks, stochastic functions, chaotic systems, transition tables, recursive subdivisions, metric indispensabilities, morphological mutations, etc. The AC Toolbox is implemented in Lisp and input syntax often reflects the conventions of this language. It is also possible for a user to extend the Toolbox by adding Lisp functions. For example, additional generators can be defined in Lisp to use with the Toolbox.
