Welcome to the home page for Polytone Additive Microtonal Synthesizer (AMS)! Polytone AMS was written during the summer of 2023 as a laboratory for experimenting with additive synthesis, temperament and microtonality. It began life as a Pure Data patch, written in 2006 and 2007, which was originally intended to simulate a Hammond drawbar organ. It was later expanded to incorporate microtonality. The microtonal aspect of the app was inspired by the work of Harry Partch and his 43-tone scale. For a detailed account of Partch's musical system, I highly recommend his book, Genesis of a Music.
