You may remember Jerry Kovarsky’s “Discovering Digital FM…John Chowning Remembers” article in the FM101 Series,. Jerry is back with an interesting two-part series entitled “History of the Synthesizer”. In part one he covers early precedents, the development of subtractive synthesis and modular synthesizers and the first Yamaha synths like the SY-1, GX-1 and CS-80. Check out History of the Synthesizer Part One here.
