Matriosity is a serial matrix creation tool. It allows users to enter in a prime row, either as numbers (1-11, and either 0 or 12 for C) or letters (C, C#, etc.). It then generates a serial matrix, displaying the data as per the users' preference as numbers or letters, and displaying the prime form of the matrix's dyads, trichords, tetrachords, and hexachords. Matrices created by Matriosity can be saved for later and printed. Version 1.1 supports row playback.
