Octave Plateau Voyetra Eight 8 Voice Analog Synth

Note: links to listings are affiliate links for which the site may be compensated.

via this auction

"The Octave Plateau Voyetra Eight is one of the rarest and most sought after polyphonic analog synths ever made for good reason. These synths sound amazing. In my opinion it is the thickest and creamiest poly I've ever used and I've owned most of them. The design was way ahead of it's time and it's a shame Octave didn't produce more units which makes them incredibly rare. They pop up maybe once or twice a year for sale and get snatched up pretty quickly.

This V8 is in great shape. I have owned it for over 20 years and it has been in a rack all of that time. It was last serviced by Jeff Blenkinsopp who worked for Octave back in the day. The unit is working and sounding great. It will be very well packed because these units are heavy and delicate beasts."

"There is barely a mark on this and it plays without any issues. Pots could do with a clean to remove any scratchiness but its due for a service since it's been quite a while since the last one. One key is slightly more elevated than the others - a very easy fix apparently."

Rossum SP-1200 Now in Production

This one was spotted and sent in via Soviet Space Child.

via @rossumelectro "SP-1200 reissue units are in production!

How many Easter eggs can you spot on these circuit boards?

A continuation of Dave’s fifty-year tradition of instruments made to last, the Rossum SP-1200 reissue is expertly engineered by its original designer for decades of reliability and is built locally in the United States. Assembling and testing the instruments in close proximity to Rossum’s California headquarters allows for SP-1200’s sonic character to be delivered according to the most exacting quality standards.

On the rear of the main circuit board, users will find dedicated, balanced jacks for all filtered and unfiltered channel outputs as well as the mix output and a new sample input monitor feature.

Throughout the process of creating the SP-1200 reissue, Dave was delighted that with very few exceptions, authentic components exactly the same as those found in the vintage classic instrument could be used throughout and took great care to maintain the classic SP-12 and SP-1200 circuit board layouts. Inside and out, SP-1200 is faithful to the original operation and preserves the coveted, authentic sound and character of the classic vintage instrument. Through this labor of love, Dave was able to create an instrument that should sound exactly the same even to the most discerning ears."

Featuring Jean-Michel Jarre.

"Discovery of a forgotten synthesizer!
Students from the agricultural high school in Courcelles-Chaussy (France) discovered by chance a synthesizer from the 1960s. They went in search of Louise and Marc Voksinski [Wolzinski], the genius creators of this machine. During their investigation the high school students will cross paths with Jean Michel Jarre. The documentary produced as part of a video workshop turns into an exceptional dive into the world of electronic music."
