Matrix Maker X is newest version of a Macintosh application designed for use in the composition and/or analysis of twelve-tone music. Matrix Maker X is a continuation of the development of Matrix maker, previously available for use with Macintosh operating systems from System 7.5.1 through OS 9.x. This new version, which sports a completely new and more intuitive user interface and a host of new features, is a Mac OS X-native application built with the Cocoa API and will run on only Mac OS X 10.1.2 or later.

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. At present, this feature is accessible for hexachords and complete twelve-tone sets only; a future update will include tetrachords and trichords as well.

This version replaces v 1.1.3 with a new Universal Binary application that runs natively on both Power PC and Intel Macintosh computers under Mac OS X. V 1.1.5 also adds the ability to print the analysis on a separate page and moves to a "drag install" rather than installer-based installation method, with the Matrix TrueType font included within the application package rather than installed separately in the fonts folder.

New in v1.1.6

• Corrects a bug that prevented the opening of older files created using a different processor type (i.e., PPC vs. Intel)
