Can anyone point to a mathematical definition of the term 'phase distortion' as implemented by Casio in their VZ-1 synthesizer ? Is this topic covered in the Moore book ?

Charles Dodge and Thomas Jerse authored a computer music textbook (can't remember the title, but it has "computer music" in it), published by Schirmer, which has a description of the phase distortion technique in the chapter "Distortion Techniques." Hope this helps. The book was published around 1986 or 1987. **************************************************************** * Greg Sandell (sandell@ils.nwu.edu) Evanston, IL * * Institute for the Learning Sciences, Northwestern University * ****************************************************************

(Companies always have to invent new names for things to make it seem like they invented it.) I don't have the Moore book handy, but it is covered in Dodge and Jerse _Computer_Music_ (1985) and more in depth in an article by Marc LeBrun "Digital Wave- shaping Synthesis" in the Journal of the Audio Engineering Society #27 (1979).
