Founded in 1975<ref name="ss">[http://gyraf.dk/schematics/VCAs_Ben_Duncan.pdf ''VCAs Invesigated part two''] by Ben Duncan, Studio Sound, p.60, Jul. 1989</ref> by John Robert Burgoon,<ref name="hae">[https://web.archive.org/web/20130103111420/http://www.anchor-electronics.com/about_us/about_us.html History of Anchor-Electronics] (archived)</ref> Solid State Music Technology (SSM) originated out the [[Wikipedia:Homebrew Computer Club|Homebrew Computer Club]], an early 1970s Silicon Valley computer hobbyist group.<ref name="emwssm" /> It was one of two companies that in the mid-1970s designed and sold [[analog]] [[integrated circuit]]s used in [[synthesizer]]s, the other was [[OnChip Systems|Curtis Electromusic Specialties]]. |

SSMs first products were computer boards for the now-obsolete [[S-100 bus]] standard, including some boards intended for music applications. As [[Dave Rossum]] told the story in a 1981 interview with [[Polyphony (magazine)|Polyphony magazine]], an engineer named [[Ron Dow]] had come to [[E-mu Systems]] looking for funding to develop a [[voltage controlled amplifier]] on a chip. However, the proposed design would not have been compatible with the [[modular synthesizer]]s that E-mu was selling at the time, so they turned Dow down. Dow then went to SSM and they agreed to fund the project and market it. The result was the first synthesizer-specific integrated circuit, the SSM2000 VCA. The following year, Dow came back with an idea for an improved design that was compatible with E-mu's systems and E-mu became involved with SSM in the design, the result was the SSM2010.<ref name="emwssm" /><ref name="dri">[http://www.siliconbreakdown.com/rossum_interview.htm Interview of Dave Rossum] by Jay Lee in Polyphony Magazine Nov/Dec 1981</ref> |
