|The unreleased mono version of the Voyetra Eight was naturally called the Octave-Plateau Voyetra One Programmable Monophonic Synthesizer Module.
While this may be the case internally. The two models differ quite a bit with the Voyeta One having more dedicated controls for the VCOs, filter, envelope, LFO, output and what appears to be modulation routing.
The Voyetra One model featured all of the features of the poly version as well as a built-in keyboard sequencer, quad-modulation bank system, lead performance options, and an audio gate input for trigger sounds from external sources.

||As with a piano, the harder you hit a key, the louder the sound, unlike most organs which always produce the same loudness no matter how hard you hit a key.
||Pressing a key after you activated it. Channel Aftertouch, no matter which key, it will send a Channel message. Poly Aftertouch, sends the pressure per key instead of the whole channel.
|Values for OSC, LFO, Filter, Envelope are per voice unless stated otherwise.
