Superbooth 2018: Black Corporation Kijimi Demos

Black Corporation Kijimi - Superbooth 2018 Published on May 5, 2018 Sound On Sound magazine

Note: Kijimi is actually based on the RSF Kobol mono synth. via the creator himself, Roman Filippov: "It’s a polyphonic kobol more than polykobol, since it uses ssm2040-like filters, not ssm2044"

"The Kijimi from Black Corporation is a modern recreation of the legendary RSF Polykobol synthesizer. Find out more..."

RSF Kobol Expander II Analogue Analog Modular Synth

Note: Auction links are affiliate links for which the site may be compensated.
via this auction

"RSF Kobol Expander II, an ideal partner for your RSF Kobol Expander but also just as easily integrated into a vintage modular or semi-modular synth system such as those from ARP, Moog, EMS, Roland, etc as well as modern modular synthesiser systems from the likes of MOTM, Synthesizers.com, Analogue Systems, Analogue Solutions, Doepfer, & all the Eurorack variety...

These Expander systems were made by Ruben & Serge Fernandez of the RSF Synthesizer Company in France from 1979-81. It uses an SSM 2050 chip for the envelope generator as well as other rare IC's from that era alongside analogue circuit design.

Certainly vintage, it seems the Fernandez brothers were inspired by the Moog & Oberheim synths of the day but as the vintage synth crew know all too well, RSF instruments had a character all of their own, with some unique features that allow for amazing flexibility, especially on the Expanders, thanks mainly to extensive Control Voltage (CV) implementation for all the modules within the unit, as evidenced by the number of jack sockets around the edges- 40 in total. (Note these are for 1/4" jacks & have been cleaned.)

There were only around 200 of these synth Expanders made so certainly a VERY RARE item.

Effectively 10 analogue synth expander modules housed in a 4U 19" rack. (Not including the multiples.)

Contains the following modules:

1 Ring Modulator
1 ADSR envelope
1 VCA
1 LFO
1 Mixer (3 Inputs & 1 Output)
1 Sample & Hold (S&H)
1 Noise Generator
1 Voltage processor
1 Gate Delay
1 Envelope Follower
2 Multiple Jack Groups (One group of 4, one group of 3)"

RSF Kobol Synthesizer with Memory Slots and Built-in Sequencer

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

via this auction

"This unit works 100 percent and is in a very good condition. The RSF Kobol was the French synth company's first compact keyboard synthesizer. It is a monophonic analog synthesizer with traditional controls, knobs, switches and two oscillators for a good solid analog synth sound. Unique are the 16 memory slots for saving your sounds and the built in sequencer.

Although it is mostly a traditional analog synth with stable oscillators and lots of knobs that allow you to control the ADS envelope, the filter section and the nice LFO, it did offer some unique features for its time. Most notably, the oscillator waveforms can be continuously swept across for a very cool morph from square to saw to pulse, etc. This, as well as note on/off and other parameters can be controlled via CV/gate. External sounds can be processed through the delicious SSM Kobol filter and envelope sections too."

via this auction

"Rare semi-modular rack mount mono synth, made by the Fernandez Brothers Ruben & Serge, in France between 1979-82. Only 800 units are estimated to have been produced.

This functions as a standalone synth, unlike the Expander 2 which offers additional features for the Expander. I sold my Expander 2 many years ago to a buyer in Spain under my redstartradingltd eBay user ID.

For recent feedback see the Oberheim DMX sold a year ago on this account & other high end audio items.

The Kobol Expander was serviced by synth Prof Andy Jury back in 2014 for which I have a pdf copy of the receipt but would benefit from another service for calibration as below.

The Maplin 5600S analog vintage synthesizer flagship (Video 1)

YouTube via scienceforce

"This is a vintage Maplin 5600s stereosynthesizer. This sequence is based on his two transient trapezoid envelopes. It's a very nice matrix synthesizer with many parameters ...much more than an EMS VCS3. His Matrix has 30 x 30 contact points (900 in total) for complex I/O and control voltages.
It has a built in spring reverb and an amazing cv controlled phaser.
The "kick" come out from a RSF Kobol driven by the Maplin 5600 trigger."
