In this historical video excerpt, David Vorhaus talks about two of his analogue inventions - the MANIAC analogue sequencer, and the Kaleidophon from 1979.

Syrinx was a Canadian electronic music group active from 1970 to 1972. Propelled by the compositions of keyboardist John Mills-Cockell and backed by saxophonist Doug Pringle and percussionist Alan Wells, the group broke musical ground with their innovative use of the Moog synthesizer and their world music inspirations. Their song “Tillicum” received national attention as the theme music for the television series Here Come the Seventies.
