JvR Elektor Formant Modular Systems

JvR Formant 909 Drum Synthesizer video upload by Jos van Ras

JvR Elektor Formant SEMI Modular Synthesizer. (NEW)

JvR Elektor Formant SEMI Modular Synthesizer with VCF 12dB and ARP4072. (NEW)

"This new Elektor Formant built by me with the same specifications as from the 70s-80s.
The modules are designed in a flat design so no wiring to the Pots, Switches and Jacks !!
See for more info on"

Also see the JVR SYNTHESIZER SYSTEM demo by Jason Basson. Curious if it's the same Jos van Ras.

Analog Modular Live Chaos Solo-Performance

video upload by

Another Live Performance with my DIY Analog Modular System.
I have used nearly all my Devices in this Song
The Software that is driving my two Polyend Midi to CV-Devices was
described in an earlier Video (You can download it for free)
The Devices in the order of the Song:
-Orchestrion analog String/Choir machine with second Resonator
-Bass Synth
-Elektor Formant with Synthacon filterclone as Subbass
-Analog Drumbox with 4 DS7-Clones
-Doepfer DIY
-Analog Groovebox with YuSynth Metalizer
-Noise-Toaster designed by Ray Wilson (Musicfromouterspace)
-Strings/Choir Synth 2.0 for first Melody

ELEKTOR Formant synthesizer with some nice mods

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

via this auction

"1970’s Netherlands DIY ( the Magazine “Elektor” provided the schematics and parts )

With added CV and GATE input on female stereo jack, and PORTAMENTO added to the modules ( really nice big vintage knob for timing adjustment )

It originally came with a keyboard ( see last two pics ) which connected to the unit, I still have it ( not working but easy fix ) and I can send it with the unit for free, it’s a 5 octave board though so shipping will be substantially higher.Since I added CV/gate input and portamento I never looked back,so I didn’t fix it.

Two extra non original modules: phaser and pano ( panning module ) are installed, the phaser works but I never really “got it” as it doesn’t really seems to “phase”.

Included are also a bunch of patch cables, the original Dutch manual, and a diagnostics cable which connects to the modules and modules chassis, so you can work on the module outside of ther housing.

Everything is working, with maybe a minimal scratchy pot or switch or two, but for around 50 years old it’s in absolutely great shape! Nothing dramatic

The wood-laminate has a few 'missing pieces'"

Elektor Labs J2B 9bit synthesizer midi / Soulsby Atmegatron clone

Note: Auction links are affiliate links for which the site may be compensated.
video upload by Elektor TV

Elektor J2B Synthesizer First Demo of Prototype from 2014.

"This video shows Elektor's J2B Synthesizer prototype running a soft synthesizer engine ported from the ATmegatron by Soulsby. Listen carefully to the sounds produced by this beast and admire the way you can control it. LPC1347 rulez the waves :-)"

via this auction

"This is a port of the Soulsby Atmegatron 8-bit monophonic synthesizer to the Elektor J2B LPC1343 ARM Cortex-M3 board. The original Atmegatron is based on an 8-bit, 32 KB flash memory ATmega328 and the firmware is available as an open source Arduino sketch. The J2B board has a 32-bit LPC1343 ARM Cortex-M3 processor with 32 KB flash memory.

The Atmegatron has two rotary encoders, eight potentiometers and a pushbutton. Two potentiometers are for volume and bass boost, the others control the synthesizer itself. The J2B board can have up to nine rotary encoders, or eight plus a pushbutton.

The Atmegatron uses a bunch of bi-color LEDs to interface with the user. The J2B can have an LCD.

The Atmegatron uses PWM to produce its sound, the J2B has excellent PWM capabilities.

Based on the previous observations, porting the Atmegatron to the J2B should not be a huge task, which is why I started doing it. The most daunting task was to replace the analog potentiometers by rotary encoders while keeping the same feel.
Two rotary encoders replicate the Atmegatron encoders, six others simulate the potentiometers. The bi-color LEDs are replaced by a 2x16 LCD, but I added two bi-color LEDs to indicate the red/green modes of the synthesizer.

A cool thing of the J2B is its built-in USB capabilities making it possible to update the firmware from any Windows PC simply by copying a file to the board which is seen as an external drive. No programmer needed at all.

PWM capabilities of the LPC1343 are a bit better than those of the ATmega328, which allowed me to increase the sample frequency and gain a bit, making it a 9-bit synthesizer. So, in theory, the sound quality of the J2B synth should be a little better than the Atmegatron."

Clouds-Two DIY analog String Machines

video upload by Andreas Remshagen

A Live-Performance with my two DIY String-Synths
I used the Strings-Synth and the Strings-Choir-Synth 2.0
The Melody comes from the Elektor-Formant and the Drums are from my analog DS7-Clone Drumbox.
All Synthesizers are driven from my Flowstone Sequencer-Software and two Polyend Poly Modules
The effects are from the Elektor Formants Noise routed through a Steiner-Parker Filterclone and Ray Wilsons Noisebox (
All String-Machines are also based one Ray Wilsons cirquits
The Solo-Synth plays the YuSynth-VCO. The ADSR is connected with
the VCO`s CV in and gives the character of a Japanese Flute

1977 Elektor Formant synthesizer demo

video upload by Simon Claessen

"First try after extensive restoration of this beast. Accompanied by the DDrum AT and a Beatstep pro for the triggers and modulaton.

I still have to tune all the oscillators but all the crackling potentiometers, jacks and non responsive keyboard is fixed now"

Elektor Formant - analog Modular Synthesizer

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

via this auction

"It is a DIY system, professionally built and last year overhauled ( capacitors, ICs, potentiometers, switches, etc renewed ). All functions of the modules are given. The knobs work without any noise beside. The whole system is designed 2 voices and internally pre-wired, so that at the COM module the final signals concerns ( VCO - VCF - VCA , each with ADSR ; LFOs are at VCOs, . . ) The sequencer is a 16 step sequencer or two times eight steps. Start/Stop and Reset buttons . The only weak point on this system is that the front panels are not fixed at the front. They do hold through the rear connector, but should be better secured for transport and more intensive use. Total : 1x step sequencer, 4x VCO , 2x VCF 24dB, 4x ADSR, 2x dual VCA, 1x LFOs , noise module, COM (EQ+Output ), keyboard module, power supply 220V"

Prophet~5 re-joins the crew in its new compact and more reliable revision 4 desktop format.

video by Vykaar Tones

"My very first experiments with integrating the Prophet 5 desktop with my other equipment. There are many other better demonstrations of the Prophet 5 on its own elsewhere. RS09 is above the P5 and ARP Odyssey is top left. Elektor formant is played from the left Keystep 37 and Blofeld keyboard is below that. The nord electro 6 is out of view at the bottom of the stand."

"This very rare Elektor synthesizer is for sale. It was built in the eighties and it worked. Over the years some parts have been removed and now need to be added. complete with assembly instructions."

The last, and only other one to be mentioned on the site, was back in 2008 here.

Elektor Formant Modular Analog Synthesizer Demo

video by Vykaar Tones

"The Elektor Formant made in this one off unique style in 1978. Most were made using separate panels available from the Elektor magazine but this one is a custom build. 3xVCOs, VCF switchable HP or LP and 6,12,18,24dB, ADSR and AD envelopes. Dual VCA. Resonant filter module, ring modulator and envelope follower. White and Pink noise, LFO and TR808 cymbal tone generator added by me a few years ago. The CV and Gate are provided by a 960 sequencer and CV transposed with a Keystep37."
