McLeyvier Amadeus synthesizer (computer music system)

This artifact helped pave the way for the evolution of computerized music in contemporary culture. Often referred to as the McLeyvier, this is a computer-controlled analog synthesizer designed for composing, sequencing, performing, editing and notating music. Though somewhat revolutionary at the time, its development coincided with the rise of digital synthesis—a factor that made this analog machine fade into obscurity. Its inventor, David McLey (1948 – 2010), was an American-born musician and instrument designer who spent the latter part of his life in Toronto.
