The rare EML SynKey #synth

12/28/25 ARP 1623 + ElectroComp EML 200 + Peavey DDL-3 + CXM 1978

video upload by Cfpp0

"I think this is the first time I sequenced the EML 200 with the ARP 1623. The sequencer is 1 volt per octave and the synthesizer is 1.2 volts per octave, but it still works. Here the gate bus 1 on the ARP is triggering the envelope on the EML, which controls the VCA both VCOs are running through. That signal then runs through the EML spring reverb into the Peavey DDL-3 delay to the Mackie Onyx 1640 mixer, where the dry is panned left and the wet is panned center. Both have stereo reverb blended on the CXM 1978."

"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."

"This unit was previously modified to include an audio output jack for vco2. This allows frequency modulation (FM) of the oscillators or filter which nicely expands this examples sonic palette beyond a stock 400's.

We did the following work to this unit. The items at the top of the list are things we consider normal servicing. The ones at the bottom labelled preventative are future-proofing measures that other sellers rarely take (they often don't even service them either).

Cleaned inside and out.

Replaced power cable.
Cleaned and lubed switches and pots.
Replaced jack washer nuts.
Replaced some screws.
Replaced all electrolytic capacitors - preventative.
Calibrated vco1 vco2 cv exp cv - a must after a recap.
Replaced IC socket (14pin x 16) - preventative.
Replaced all pins inside multipin connectors on unit and inside connector cable - preventative."

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."

7/31/25 EML 200 + Metasonix S-1000 Wretch Machine + SSL 1600 + acRLS

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."

"I forgot to upload this and now I don’t remember what was going on offscreen, but because the 1U DeltaLab Effectron II appears above the top EML 200, there must be a rack of 5U above, assisting the EML 200s."

Additional Tone Tweakers Listings

"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."
