Matrix Maker X for Mac

From M-T Software:

Matrix Maker X is designed to facilitate the easy creation and formatting of twelve-tone matrices (12 x 12 arrays) used in the composition and/or analysis of twelve-tone music, as well as the creation and formatting of 7 x 7, 6 x 6, and 5 x 5 matrices (or, for that matter, of any dimension from 2 x 2 through 12 x 12). Any number of matrices can be created without exiting and re-initializing the application; this is particularly advantageous if the program is being used in a networked environment. Extensive documentation in HTML format can be viewed by utilizing any of the current Macintosh browsers.

Matrix Maker X can not only create and format matrices: it can also analyze the properties of the set. This feature is accessible for hexachords and complete twelve-tone sets; the application will analyze sets for both hexachordal and tetrachordal combinatoriality.
This application offers the following features:

• OS X support (this version runs on OS X only)
• New GUI
• Analysis of properties of sets now includes both hexachordal and tetrachordal combinatoriality
• Ability to play the set so that you can listen to it
• Dynamic editing of set properties
• Additional on-line documentation available through the Help menu includes a brief overview of twelve-tone theoretical concepts
• New installation method (drag-install instead of an installer)
• Adds the ability to print the analysis on a separate page
