The RSF Kobo is a French monophonic synthesizer released in 1978. Described by purists as the French Minimoog.[3] It could process external sounds to through the envelope and filter section. It was created by Ruben and Serge Fernandez. Less than 200[4] were made as they were not mass produced. At the time a possible alternative or addition to the Minimoog. The Kobol is a very versatile instrument, offering many sought after features of other analogue synthesizers of it's time.[5]

Rack Mount

A rack-mount system was released in 1979.[6] There were four different typkes: The Kobol Rack (Expander I) was only the VCO/VCF/VCA/LFO sections of the Kobol in a rack module. The Expander 2 was an add-on to the Kobol that added new processing modules such as ring modulation, sample-hold, and envelope followers as well as extra VCA and LFO modules.
