The Voyetra One is a monophonic version of the Voyetra Eight. They both share the same fron panel design, however their color schemes were different. As with the Voyetra Eight, the Voyetra One was designed to be used with a matching monophonic MIDI keyboard controller. Somewhere out there there is a prototype of this synthesizer called the "Voyager One". The model name was changed before the planned release in 1983. However, it that it ever made it into production.
