"Functions well

Received this in trade and do not have the finished module, so I'm unsure how close this is to the final model, appears on the surface to have one less input of modulation and a simpler display.

Currently behind a 19" metal panel to allow for standard rackmounting but could be easily adapted to a custom case. Connects via an included header adapter to standard Eurorack power"

RSF Kobol Expander I and II

via this auction

"The rack version of the RSF Kobol with a great sounding and very snappy SSM filter.
The Kobol Rack (Expander I) was essentially 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 some new processing modules such as ring modulation, sample-hold, andenvelope followers as well as extra VCA and LFO modules.

The Kobol looked and sounded great, andwas quickly snapped up by the big names in synthesizers of the time. But beinga small French company, RSF were never able to truly mass produce these.
About 800 Kobol Racks were made, 200 Expander 2's. This makes them quite rare!

They have been used by Vince Clarke,Vangelis, Jean-Michel Jarre, Depeche Mode, Peter Gabriel and Hans Zimmer.

The RSF Expander II rack mount modular synth was manufactured as a companionoption module for the Kobol Expander I synthesizer. The19" 3 U space unit features a Ring Modulator, Envelope, a VCA, an LFO,Mixer with 3 inputs and 1 output. Additionally it has a Sample & Holdmodule with internal or external clock, a Noise Generator, Voltage processorthat is delectable Linear or Logarithmic, Voltage Inverter, Gate Delay, anEnvelope Follower, Lag Generator, and finally 2 multiples."

Googlish:

"So...here comes m,al 10 selected sound demos of the 'Yammex'. This is an expander from Klaus Dzida www.v3sound.com which is specially designed for Yamaha Tyros, Genos and PSR keyboards."

via this auction

"I bought this from Sweetwater a couple of years ago to expand the voices of my Yamaha Genos. It has many excellent pianos, EPs, horns, organs, etc that complemented and in some cases IMO sounded better than the voices on my Genos. There are several on line videos that demo the voices. Now I no longer need the V3 module (since I use my Genos with a Legends 70s piano).

This expansion sound module works with any keyboard that can send midi messages. The advantage of using it with a Yamaha arranger is you can load the voice names into your keyboard, but it doesn't use significant storage in the arranger since the sounds are all stored on the module."
