The Steiner-Parker Synthacon was a monophonic analog synthesizer built from 1975-1979 by Salt Lake City-based synthesizer manufacturer Steiner Parker. It featured three voltage-controlled oscillators (one of which could output sine and sawtooth waves and two of which could output sawtooth, pulse, and triangle waves), a two-pole resonant Sallen Key Filter, two ADSR envelope generators, a pink- and- white noise generator, and a 49-key keyboard. While the Synthacon was not a modular system, signal routing could be achieved through a series of switches.
Users and Popularity
According to designer Nyle Steiner, "...several hundred Synthacons were made and sold." Marketed for live performance and studio use, the Synthacon was used by Earth Wind and Fire, The Doors, Pink Floyd, and Frank Zappa, among others.
The Synthacon Today
The Synthacon's filter circuit can be found in contemporary modular synthesizer designs due to its low cost and relative ease of construction. A derivative of the Synthacon filter is also used in the Arturia Minibrute analog synthesizer. The filter is of the diode ladder family and features separate inputs for low-pass, high-pass, and bandpass modes. Many versions of this circuit are available.
