Moog's modular synthesizer used voltage as control

Pitch, filter and loudness were all steered by electrical signals Robert Moog built his modular system in 1964 from separate voltage-controlled oscillators, filters and amplifiers joined by patch cables. Because a voltage could control anything, a keyboard or an envelope could shape pitch and tone without a player's hands. Universities and studios bought the first systems. It sits in Mondo's music collection, one of 200 facts that each trace back to the reference below.
