"xtremely RARE item from the French Synthesizers Made By Ruben & Serge Fernandez in the 70′s. The RSF Blackbox is a small 18 keys mini synthesizer that can turn your Analog Monophonic Synthesizers into Polyphonic by the use of CV/Gate with both type of Voltage Source as CV Volt/Oct. And/Or Hertz Volts and Both Gate Types as Positive Gate (V-Trigger) or Negative Gate (S-Trigger).So basically you can control & use every kind of Analog Synthesizer with this unit like Korg, Roland, Yamaha, Kawai, Sequential Circuits, Moog, ARP, Oberheim."
Similar to the EML Polybox.
End 70-Ira I bought a Yamaha CS-30. It is now in restoration. By lack of money, I was not able to buy also this Blackbox. So my interest exists decades, which is reason to ask for the price. As this post was placed in 2019, I suggest it is sold long time ago. Nevertheless I hope to get some idea what the device would cost and if someone knows where to buy it.
