"Here is a very rare occasion to buy a RSF Kobol and this one is in full working condition. Internal battery has been replaced. Its worse cosmetic flaw being the crack in its right flank as shown in the pictures, which has not cracked further for the last 20 years. Feels totally solid. Otherwise the cosmetic condition is excellent. It comes (not in the pictures) with its original paper manual and in a very sturdy custom wooden box with foam inside that is also very heavy. So if you want to ship you will have to tell us if you want the box or not as since it weighs almost as much as the synth it will have a significant impact on the shipping cost. The RSF Kobol is one of the very best vintage monophonic synths ever designed with its distinctive powerful and precise sound and one of the sexiest User Interface ever designed. Plus it has 16 memory slots and the ability to sequence these slots making it one of the most powerful sequencers of its time. You can trigger it from any 5V clock. More information can be found here : https://www.vintagesynth.com/rsf/kobol-expander and here : http://rsf-synth-official.com/cadre.html"

"Only around 200 units were built in the '70s and maybe only 50 are left - probably less.

The unit is all original with big knobs (hell yes!) and a sequencer that steps through presets, not notes!"

Rare "Engineer Sample" Behringer Kobol Keyboard Spotted

This one was spotted and sent in via
M Me.

"Not in production. Not available anywhere.

Perfect for your Youtube video or synth channel.

Rare opportunity to own one of a kind synthesizer keyboard.
This is the Behringer Kobol Keyboard. There's a label in the back showing this to be an "Engineer Sample".

All controls and keys seem to be working. Although given this is not a production model, there could be quirks. The Pitch and Mod wheels light up when activated. The LED bar changes when knobs are turned.
I had tested only the audio outputs - headphones, main out, and amp out. Other connections and USB are untested.

Good overall physical condition, but there are very visible scratches and dings and dents on the panel, as shown in the photos.
The back stand has 3 positions for tilt adjustment."

RSF Kobol Expander Modular Synth System 1978

Pics of the inside below.

"Up for sale is an extremely nice clone of the RSF kobol expander 1 and an original RSF kobol expander 2. The clone is made with original SSM chips for the filter and envelopes and original ua726 for the oscillators. I was able to tune it up so that the knobs match my original expander exactly and it now sounds 100 percent identical. It also runs off of 18 volts and is even slimmer than the original. This expander alone would make a great travel synth.

I had plans to make new faceplates and build a travel case for these guys but I have too many projects going on right now. It’s a great oppurtunity to get these two for a bit cheaper than what they have gone for in the past. The expander 1 is simply the best bass synth ever. Super snappy and great for leads as well. The behringer and moslab clone both missed the mark in my opinion. There’s something very special about the wave shaping of the original and I was amazed that I got the clone to imitate this behavior exactly. The ringmod on the expander 2 is really interesting/ dirty pairs well with the wave shaping. Be careful with purchasing kobols as there are clones out there. Always ask for inside shots of the units. I A dead give away is usually the switches.

The expander 1 is in perfect condition. The expander 2 has a slight dent on the corner that was not noricable when racked and the faceplate has a few scrapes. Both are in excellent working order with no scratchy pots or anything."

RSF Kobol Expander *Vintage *Serviced

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

via this listing

"For sale is a very rare RSF Kobol Expander. Made in limited quantities in the late 1970’s. Despite its age, it has been serviced and is fully functional.

However, there are two caveats, one knob is missing, and sometimes the tuning isn’t so stable. It is analog synth, modeled after a mini moog after all."

It can also be combined with other machines.

Comes with power chord

-- -- -- -- -- -- -- -- --

The rsf's are powerfull synthesizers, built in France in the end of 70's begining 80's, with a HUGE and beautiful, super warm and wide sound.

The Kobol can be coupled with the Kobol Expander 2 and the programmer ( very very rare amazing sequencer ).

These beautiful machines are rare because they were produced by hand by two brothers for only a couple of years."

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."

EMEAPP SONIC TEST DRIVE: RSF BLACKBOX Feat. DON SLEPIAN

video upload by EMEAPP

"Another rarity from the halls of EMEAPP, here we have the ultra-rare RSF Blackbox from the late 70s. While it doesn't look like much on the outside, it is capable of a pretty amazing task: it can turn a monosynth into a polysynth by using it's CV/gate output. Intended as a peripheral device for the RSF Kobol monosynth, the Blackbox is compatible with a plethora of other vintage monosynths. In this video, electronic music pioneer Don Slepian will demonstrate the Blackbox's capabilities as a stand-alone instrument.

You can find us at www.emeapp.org where we invite you to join us as a FREE member."
