DAVID COLLETT  Several months ago, I wrote a review of v1.0, praising the software and the author. At that time, I suggested that the author expand the documentation to include more explanations of the analysis. In addition, I have been waiting for tetrachordal combinatoriality analysis. In this latest version (1.1.1), the author, John, has greatly expanded the documentation and the analysis of tetrachords. In the past, I've had questions about the program and found smalll bugs. John has always been very polite, helpful, and responsive about answering email and fixing any problems. I highly recommend this software for anyone interested in studying or composing serial music. Great software, great price, great author. Thanks!
