"Up for sale a super rare and awesome Octave Plateau - Voyetra 8. There were only a few hundred of these made and you almost never see these for sale!
Selling as is.
Known Issues are: Audio outputs do not pass signal although the headphone out does work correctly. Unison L is not working but Unison R is working.
Other than that there are some scratchy switches & pots from age which are to be expected. I contacted one of the original guys from Octave Plateau and he stated " the Voyetra serial is one of the last batch manufactured so is probably a Rev4" The Rev4 is the most desirable version works with MIDI librarians like MIDI Quest Pro and has advanced SysEx. Earlier versions have a much more limited UI.
Midi In cable included. (XLR Male to Midi) See shop description."

"1970's YAMAHA EX-2 ANALOG SYNTHESIZER ORGAN. Their (sic) were only 12 of these made and it is very rare. It does work, but i dont know how to operate it. Speaker is missing its felt cover in the back, but does have a replacement for it. Pick up only in Pahrump, Nv 89060."

You can find a demo of one here. Note the EX-2 is not the pre-cursor to the GX-1. That would be the EX-42 (1970–1977, stage model, design origin of GX-1)" according to the list of Yamaha products on Wikipedia.
