The Voyetra-8 (Voyetra-Eight) is an eight voice polyphonic analog synthesizer. Released in 1982 by Octave-Plateau Electronics (later renamed Voyetra and still later merged with Turtle Beach Systems to become Voyetra Turtle Beach, Inc.), it was one of the first analog programmable synthesizers to be rack-mountable and remains one of the most flexible digitally controlled analog synthesizers.
