"Rare Synth/Sequencer in incredible condition! EML made only 300 of these. Serial numbers started at 400 I believe, from what I’ve read they start with each model number. Completely checked through and serviced. Works and sounds great, really unique HUGE sound and a really fun sequencer. We have a great record of putting a lot of care into our shipments and will ship protected. Instrument quality and playability is well documented please ask if you need any other pics or vids. Would make an amazing stage or studio instrument. A couple small scratches on the back, as pictured, slight patina on handle.

EML's 400/401 ElectroComp is a rare semi-modular analog synthesizer/sequencer that first appeared in 1970 and although it was produced until 1984, roughly 300 were made. The synthesizer (401) component can be considered a scaled down version of the EML 500 in some ways. It looks very similar in color and layout but lacks a built-in keyboard. It retains patch-cord signal patching and editing associated with modular synths as well as some switches. Dual VCOs produce a monophonic analog sound which can be shaped by the multimode resonant VCF (filter) with switchable hi, low and band pass filtering. Only sawtooth, square and noise waveforms are available from the oscillators. The envelope section offers only attack and release control (the EML 500 envelope section added sustain).

Complementing the EML 401 modular component is the 400 system which, as seen above, is covered with dozens of switches and sliders. Basically it's an analog sequencer component. It is a 12-tone diatonic sequencer with a digitally controlled voltage quantizer built-in - a sophisticated feature for the time. This allows for a variable number of steps-per-octave ranging from 5 to 60...a very unusual feature which makes the unit very useful for those exploring alternate/microtonal tunings. It also offered voltage controlled envelope generators in 16 stages! These could be programmed for creating pretty wild sequences and patterns.

The EML 400 and 401 system was a response to the popular Moog and ARP modulars from the era. It offered new ways of synthesizing classic analog sounds which may not have been better than its competition, but it certainly was unique. Today these rare instruments can still be found in use by synth anoraks around the world."

"If you are considering buying this synth, I imagine you already know a bit about it. But for those stumbling onto this listing and are intrigued, there is a video link for one example of the one for sale in use....

Allow me to offer that all I know about it.

This is a FULLY FUNCTIONAL EML Electrocomp 200. I had it restored over at Main Drag Music in Brooklyn, NY a few years back. The Power Cord is original, and I’ll include the original capacitors with the unit in a bag.

This is an exceptionally rare synth, built in Vernon CT in likely the late 60’s or mid 70’s. It was initially made to be an educational synthesizer for science classrooms to teach kids the physics of how sounds are created.

On its own, it is a modular synth island with one master oscillator that serves as an LFO and/or ring mod source & two saw tooth waves. The synth also has a spring reverb, a ring mod, and a mic amp along with a 6 channel stereo mixer (3 per side).

While it does offer keyboard control in the back, it is for a specific keyboard that I do not have, but the synth CAN be controlled via CV with an atypical 1.2V/Hz output. I have successfully controlled the sawtooth waves with an Elektron Analog Four, as they are the only wave shapes that have an input section.

This synthesizer sounds like it’s history. You can smell the capacitors in the sound. You can also actually smell the synthesizer a little bit when it’s turned on (not a bad thing, it really works perfectly). All of the wave shapes are very stable and have their own vibes that are unique from any other synthesizer you’ve heard.

This synthesizer is a weird little beast on its own, and controlled with CV it offers some beautiful sounds. As a piece of outboard gear, the spring reverb, ring mod & mic amp are awesome on drums, guitars, other keyboards, and of course the synth its-self.

For those who do experimental music, ambient music, electronic music in general or are looking for a vintage happy mistake machine to sample that also looks as good as it sounds, you’re gonna love playing with this synth.

I have taken excellent care of this synth and am sad to see it go, but it’s time for it to be enjoyed by someone else who appreciates and loves it as much as I have. I’d love to hear what you make with it and how you carry on its legacy."

"extremely good condition physically considering the age. Only issue is the control mode pot is loose, it is switchable but should be soldered into place by a technician. Comes with a volt per octave mod kit by bell synth works, ready to be installed"

Electronic Music Laboratories Electrocomp EML-101 (1972) SN 685

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

via this listing

"A beautiful duophonic synthesizer. This is the earlier model circa 1972 with a CM3 input jack - later models were changed to a SEQ input. This instrument is in good cosmetic condition for its age and it sounds fantastic.

This was first owned by San Diego State University, where I presume it had the cinch jones connector added and was etched and stickered. That connector is producing 15v at pin 5, -15v at pin 11 and is grounded at pin 4.

Any known issues are few: the pilot light is intermittent - flickers on/off and will stay off periodically. The top right corner of the case is separated at the joint but it is sturdy (pictured). There is a missing wood screw in the interior of the keyboard case (pictured). Knicks and dings here and there on the case and face plate, naturally - but really not bad.

All electrolytic capacitors were replaced in January 2019. Included is the non-destructive BellTone 1v/Octave mod kit which I never installed (pictured). The handle is an after-market replacement (not original)."

3/17/24 (bass version) ElectroComp EML 200 + Lexicon PCM 70

video upload by Cfpp0

"Some more RoboCop from the ElectroComp EML 200. Similarly hysterical patch as in the previous 3/17/24 EML 200 video, but more of a bass version this time, with lower tuning on each VCO, different on times for the spring reverb running into the switch, and a bit less swung."

3/17/24 ElectroComp EML 200 + Lexicon PCM 70

video upload by Cfpp0

"The VCO 2 pitch knob is all the way counter clockwise until 0:55, when it is turned up and the VCO goes into audible range and more FM occurs between the two VCOs. That knob continues to get turned and also some on time changes on the switch. Lexicon PCM 70 provides the stereo delay."

3/11/24 (slower range) ElectroComp EML 200 + Lexicon PCM 70 (1.3 Circular Dlys)

video upload by Cfpp0

"Same patch as in the previous 3/11/24 EML 200 video, but with a lower range setting on the master oscillator:

The ElectroComp EML 200 master oscillator square wave drives the whole wave shaper section and the switch. Sampler is fed one output of VCO 1. VCO 1 and VCO 2 outputs go to the ring modulator. VCO 2 also goes to VCO 1 CV input. Sampler outputs go to VCO 1 and VCO 2 CV inputs. Wave shaper is set to amplitude, with the ring mod output going to carrier in, and modulation input is first getting a sine wave from the master oscillator (until 0:45), then only the switch output is audible until (at 0:53) I change it to the envelope. The ring mod output also goes to the spring reverb, 100% wet, which goes to the switch. The switch output is dry, but a stereo delay from the Lexicon PCM 70 is applied to the output of the wave shaper, which runs through mixer No. 1 on the 200."

2/5/24 (atmospheric river range combinations) ElectroComp EML 200 (x2) + Langevin Filter + CXM 1978

video upload by Cfpp0

"Two ElectroComp EML 200 synthesizers are cross-patched, and their master oscillator ranges are adjusted, which affects both samplers, the envelopes, etc. The bottom EML 200 runs through a passive Langevin filter, panned left, high passing. The Chase Bliss & Meris CXM 1978 is set to a delayed reverb, with the reverb increased towards the end. Also used a Synthesizers.com Q124 mult."

"What we have today is an EML 500 Synthesizer. In the late seventies, there were a few different US based synthesizers. You all know about Moogs, Arps, EMS, Oberheims and all of the Japanese models, but EML made unique and idiosyncratic designs.

This is their 500 model, designed as a competitor for the Minimoog/Micromoog and the Arp Odyssey. In its case, it didn’t make much a ripple in the pond, but some guys from Akron liked it. Devo had a EML500 in their studio, and that should tell you all you need to know about this guy.

These are extremely rare. It is probably a Good instrument, but for this model, there aren’t a lot of choices."
