Analog Music Synthesizers
January 2006
There is no doubt that synthesizers have changed the face of music over the past 30 years. Synthesizers’ initial impact was in the area of “academic” music, since their almost brutish size, extreme complexity, and exorbitant cost fairly much confined them to university settings. But as interested experimenters became more familiar with the concepts of electronic music, and the linear integrated circuit revolution kicked into high gear, homebrew analog synthesizers started to pop up..
