"12/10-19/25 Metasonix D-2000 + Make Noise Maths + Roland SH-101 + Gieskes Starving Binary + Alesis MIDIVERB II + Peavey 1310 + Yamaha EM-100 + DBX 119 + ElectroComp EML 200

This was a test from earlier this month of a rack we installed above the Metasonix D-2000. There are two Make Noise Maths and a Gieskes Starving Binary triggering the D-2000. The D-2000 is heard as is, but it is also heard through the DBX 119, which gates the signal, and also gates a drone from the ElectroComp EML 200, which is fed through the DBX 119 at the same time. The Roland SH-101 is played manually, through a Peavey 1310 delay into a Yamaha EM-100 mixer, with the preamps cranked up and the internal spring reverb on. Everything has some Alesis MIDIVERB II."

"This EML-101 was meticulously refurbished and is better than others you may find. This process required 36 hours of highly skilled vintage synth labor, plus parts costs. This unit includes the factory installed pitch bend wheel, which is rare.

Here's a summary of some of the work we did to this instrument that should make it significantly more valuable than others on the market:

We replaced the original handle - those familiar with 101s know the handles often fall apart - we've learned not to carry them by the handle / always carry them with both hands! At the time of writing this description, we see a unit listed as serviced with duct tape holding its handle together. This unit was fully disassembled and cleaned inside and out. Replaced jack washers and nuts. Rebuilt power supply for longevity (replaced electrolytic capacitors and 2 regulators). Replaced metal latches. Replaced electrolytic caps. Cleaned jacks. Removed and cleaned all keys. Removed and replaced rubber keyboard bushings. Cleaned and lubed key contacts and bus bar. Recalibrated CV VCO 1, 2, 3, 4, VCF. Replaced trimpots exp circuit. Replaced all pots that weren't perfect, so this unit works crackle-free and feels like playing a brand new instrument."

The Vintage Synthesizer Museum Doc - A "Living Museum" where otherworldly sounds come to life!

video upload by Helium Vision

"In this episode of Helium Vision, we invite you into a world that hums with the strange and the beautiful—the Vintage Synthesizer Museum (VSM). Founded in 2013 by the avid synthesizer historian Lance Hill, this “living museum” exists in a space where the past and present come together to offer an immersive experience into the magical world of sound. It’s not just a museum—it’s a place where visitors and artists can disappear into their work, perform in a unique atmosphere, or learn the art of synthesis.

Initially opening its doors in Oakland the VSM is now nestled in the heart of Los Angeles, this space has since witnessed the presence of many modern visionaries—Damon Albarn, Egyptian Lover and Neurosis, to name a few—each leaving behind their own distinctive imprints.

Come with us, as we step into the otherworldly corners of the Vintage Synthesizer Museum and uncover the tales of the instruments that dwell within.

Classic EML 400 / 401 Sequencer / Synth

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

via this VEMIA listing

"**NEW REDUCED START PRICE** EML 400 / 401 analogue sequencer and synthesiser Very rare, old and amazing! This machine is quite confusing, but when you get to know it you can see how powerful and unusual the sequencer is. The EML400 is the best vintage analogue sequencer I have ever used. As far as I can tell, it all works, but some of the sliders are crackly. Given its age, this is to be expected. Overall condition is very good, but please study the photos. The unit is 115V, but can include a step down transformer if requested. The user manual is available to download on the internet. Does require some knowledge to get the sequencer to loop. ***Plus VAT for a UK buyer.*** VEMIA can collect for packing (24GBP) or hand delivery."

9/28/25 (bird) ElectroComp EML 400/401 + Paia 6740 + DeltaLab Effectron II + MIDIVERB II + CXM 1978

video upload by Cfpp0

"Some stringy flutes. The 16 steps on the right side of the ElectroComp EML 400 are producing V4, which is controlling the envelope decay on the EML 401. I’m resetting that loop throughout the video, to change the accents and envelope. The 16 steps on the left side of the 400 are producing V3, which is controlling the 401 filter (in high pass mode). The 400 sequence is being clocked by ALM Pamela’s New Workout, with a division of 140bpm. The 401 output hits the DeltaLab Effectron II delay hard and overloads the limiter. The delay goes from the Effectron II to the Mackie Onyx 1640, with spring reverb from the Paia 6740, gated stereo reverb from the Alesis MIDIVERB II, and pitchy downsampled stereo reverb blended on the CXM 1978. The bird was racing our ferry and won."

video upload by Cfpp0

"7/31/25 ElectroComp EML 200 + Metasonix S-1000 Wretch Machine + Synthetic Sound Labs 1600 + Analog Craftsman acRLS

It was inevitable. The Metasonix S-1000 Wretch Machine is now in the 6U rack on top of the ElectroComp EML 200 stack. Just to the right of the Metasonix TM-1, TM-1 SE, TM-5, TM-2, TM-7, and Zerosum Inertia Cenotaph. We’ve tried to find a TM-6 to add to the racks for several years now, but to no avail, so why not just put the S-1000 here? Duh. This was a test video, with the EML 200 square wave driving the Synthetic Sound Labs 1600 clock divider, which triggers the S-1000 and drives the EML 200 envelope and the Analog Craftsman acRLS shift register thing, which modulates the S-1000 oscillators, pulser, and filter. Both signals get spring reverb from the EML 200. Sounds like creatures to me."

"This EML-200 was meticulously refurbished, with future-proofing measures. This work required 28 hours of skilled vintage synth tech time, plus parts costs.

In addition to repairs, we performed the following work to this EML200:

Replaced all electrolytic capacitors - an important preventative measure.
Power supply rebuilt - another important preventative measure: Replaced power supply electrolytic capacitors, regulators, cleaned heat sync, applied silicone lube.
Replaced power cord.
Installed new rubber feet.
Replaced jack washers and nuts.
Replaced front panel screws.
Cleaned inside and out.
All jacks cleaned for better connection.
Painstakingly removed, opened and cleaned and lubed all potentiometers to eliminate crackle.
Cleaned all switches to eliminate crackle.
Installed new grommets for reverb unit.

The end result is a beautiful example of this classic instrument that works like new again and is a real pleasure to play, without the problems one would normally expect from a 50 year old instrument that didn't receive this kind of treatment. It’s ready to play and record with. See photos - this is exactly what you’ll be getting, nothing more and nothing less.

EML ElectroComp 101 – Vintage Duophonic Semi-Modular Synthesizer

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

via this eBay listing

"From rags to riches....

The short video [at the listing] shows the starting condition of this wonderful Electrocomp EML-101 synthesizer.

We commissioned the super talented Wes Curry of Curry Cases to create this absolutely gorgeous solid walnut enclosure with all new hardware and high quality soft brown leather carrying handle.

Inside, this has had much restorative work, switches and pots have all been deep cleaned, power supply fully rebuilt and all electrolytic capacitors replaced and various other repairs to bring the synth back to 100%

The Pratt-Read keyboard has been completely stripped and rebuilt with all new key bushings. Key caps have all been treated with 'retrobrite' to bring them back to white. (Some were also replaced) the result being a good looking keybed that plays like new again.

This two piece synth clasps together to be portable, but when opening, the bottom clasps then clip back into the lid so that it becomes a desktop arrangement. with the cable extended you can also mount the two pieces upto about 3 feet apart."

"6/14/25 ElectroComp EML 200 + SSL 1520 Segwencer IV + Happy Nerding FM AID

This was a test of the 5U version of Happy Nerding FX AID with the ElectroComp EML 200. It’s processing the master sine wave from the upper EML 200, and modulated by the master triangle from the lower EML 200. The upper EMl 200 ring mod and switch are also being used, with the switch getting pulsed by the lower EML 200 master square wave. The Synthetic Sound Labs 1520 Segwencer IV is also being used, modulated by the lower EML 200 master triangle. The spring reverb is from the EML 200."

"6/4/25 ElectroComp EML 400/401 + Roland TR-909 + General Radio 1564-A + Alesis MIDIVERB II

The bass pulses are the Roland TR-909 low tom through the General Radio 1564-A, with reversed reverb from the Alesis MIDIVERB II. The TR-909 trigger out is driving the ElectroComp EML 400 sequencer. I recorded two takes of the EML 400 sequencing the 401 (with and with reverb), but ended up stacking them both."

5/31-6/3/25 multitrack test of Roland TR-909 internal clock

"5/31-6/3/25 Roland TR-909 + General Radio 1564-A + ElectroComp EML 200 + Ace Tone MP-4 + DeltaLab Effectron II + Peavey DDL-3 + Alesis MIDIVERB II

This video started out as a quick test of a black General Radio 1564-A Sound and Vibration Analyzer, with the 1564-A processing the Roland TR-909 low tom. The 1564-A is kind of crusty, but it works. Then that video prompted a test to see if the Roland TR-909 internal clock is solid. It is very solid; there are about five different takes layered in this video, and they’re all using the 909 internal clock. The kick, clap, rim shot, hats, ride, low tom and high tom are all used, with the low tom getting either all pass processed or 1/3 octave processed. The rim shot also gets processed towards the end. And the high wood block sound is the 1564-A getting pinged by the 909 trigger output (which is set by a rim shot pattern). The clap and the high tom are processed by the Ace Tone MP-4 preamps and spring reverb. The Alesis MIDIVERB II is used heavily for reverbs, including some absurd reversed delays. The Peavey DDL-3 and the DeltaLab Effectron II are used for delays throughout the video. The drones are two ElectroComp EML 200 synthesizers."

EML ElectroComp 101 – Vintage Duophonic Semi-Modular Synthesizer

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

via this Reverb listing, also on eBay

"A rare and revered classic, the ElectroComp 101 was Electronic Music Laboratories’ evolution of the original ElectroComp 100—crafted by the Connecticut-based company known for its educational and experimental instruments. Released as a flexible alternative to the ARP 2600 and Minimoog, the EML-101 brought serious innovation to semi-modular design.

Unlike its contemporaries, the 101 featured four voltage-controlled oscillators—two of which operate sub-sonically for LFO duties—with morphable waveforms accessible via rotary selectors. It’s duophonic, allowing up to two-note polyphony, and provides a unique modulation architecture where control voltage and audio signals are treated interchangeably, offering highly creative patching possibilities.

A 12dB/oct multimode filter (low-pass, band-pass, and high-pass) with resonance adds tonal versatility, and the onboard ring/amplitude modulation, sample-and-hold (“Sampler”), and dual envelope generators give the 101 deep sound-shaping power. Thanks to its use of op-amps instead of temperature-sensitive transistors, the 101 also boasts impressive tuning stability compared to Moog or ARP synths of the era.

Designed with portability in mind, the unit folds neatly into its own wooden case, making it ideal for studio or stage use.

Originally marketed to universities and educational institutions, the EML-101’s modular flexibility, rich analog tone, and rock-solid build quickly caught the attention of professional musicians and sound designers, cementing its place as one of the most powerful portable synthesizers of the 1970s.

Features:

Polyphony: Duophonic

Oscillators: 4 VCOs (2 with sub-audio range; variable waveforms + noise)

Filter: Multimode 12dB/oct filter (low-pass, band-pass, high-pass) with resonance

Envelopes: 2 ADS generators

Effects: Ring/Amplitude Modulator, Sample-and-Hold

Modulation: Any CV or audio signal can be patched freely

Keyboard: 44-note

Control: CV/Gate compatible

A previously used item that shows signs of cosmetic wear but is fully operational and functions as intended—a vintage gem ready to inspire."

Electrocomp Synthesizers EML-200 and EML-300 Fully Refurbished

video upload by tonetweakers

"Here’s the last EML-200 and EML-300 we fully refurbished. The EML-200 took 25 hours and the EML-300 took 13 hours so far but needs what could be several more hours of work because a couple of the keypad contacts are still malfunctioning occasionally after the first cleaning. Refurbishing 50 year old electronics to work like new again takes a lot of hard work and attention to detail.
