Transposition Matrix 

There are two types of Matrices available: Transpositional  and Extended Just. Each presents a palette of ratios to be used in the formation of new Keyboards.  

A Transposition matrix is formed by selecting two keyboards as axes, yielding a matrix of ratios that are products of the two keyboards (cell ij =  celli0 * cell0j). This forms a set consisting of each keyboard transposed by each step of the other. Use the Transposition Matrix... item of the Tools submenu to create a Transpositional Matrix.  After choosing Transposition Matrix... click on any two Keyboards you want to multiply. After you've selected your Keyboards, choose OK in the Transposition Matrix Panel.
