Analog Music Synthesizers
January 2006, Page 57
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..

Spreadsheet - The Forgotten Analog Design Tool
October 2006, Page 59
Nowadays, there’s a ton of software kicking around to greatly simplify the design and construction of electronic circuits. Packages to capture schematics, perform simulations, lay out printed circuit boards, and so forth, abound. The trouble is, most non-professionals can’t justify the typically stiff expense of these,especially when not used on a daily, income-producing basis...
