"The material exhibited in this book is the result of my experience gained in over twenty-five years of activity as a professional keyboardist, sound designer, producer, teacher and from an intense continuous research in the field of synthesizers that lasted several years and is constantly evolving. This text is aimed at all those who do not have in their cultural background those technical and scientific notions necessary to better understand the dynamics that are the basis of electronic music and synthesizers, to those who want to deepen the topic if they already have knowledge or to those who have the need or curiosity to deal with more specialized texts for each specific topic at a later time." (Andrea De Paoli)
