Matrix Maker X

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. Matrix Maker X is a Mac OS X-native application built with the Cocoa API and will run on only Mac OS X 10.1.5 or later. Matrix Maker X 1.1.7 is compatible with Mac OS 10.5.x ("Leopard"). 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, matrices 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. The application can check a set for hexachordal and tetrachordal combinatoriality, all-interval properties, and R- and RI-degeneracy and can also do limited analyses of hexachords and sets of other than twelve or six members; a future update will include trichordal combinatoriality as well.
