7/1/26 Roland TR-909 & RE-201 + ElectroComp EML 400/401 + SDS1 + Dukane 2a76 + MIDIVERB 2 + CXM 1978

video upload by Cfpp0

"This video is shot at a more revealing angle than usual, to document the setup before we change it. When we added an EML 400/401 to our EML 200, we made custom shelves to line the three panels up on a table. But we got a great deal on a second EML 200 during the pandemic, so that got installed on a metal shelf over the first EML 200. The studio kept growing over the years, with lots of revisions on how it is all arranged, but the EML 400/401 hasn’t moved an inch. I never liked this hockey stick configuration and have always felt the EML 400/401 is a bit underutilized. This summer we’ve decided to move the 400 above the 401, creating a big EML block, so that the 400 is closer to the 200s, to the Buchla system, and so it’s easier to reach everything at once.

Anyways, the point of this patch was to use V1 on the right set of stages to reset the left set of stages. It’s a fun trick because you can control when and how often you want to reset the sequence using the sliders. The TR-909 is externally clocked by ALM Pamela’s New Workout at 130bpm. The kick and rim shot are saturated by the Dukane 2a76. The snare sound is the Simmons SDS1, triggered by the rim shot trigger output on the 909. The EML 401 filter is in high pass mode. At 0:43 I drop the kick, unmute the clap and hats, and turn off the voltage control of the envelope, which makes it sound like a goose. At 1:13 I change the TR-909 pattern and switch the routing of the lower voltages on the 400, from V4 to V3 and from V3 to V4."

"We recently acquired these two consecutively cute curiosities courtesy of a very inspiring and equally interesting gentleman and great friend of the late Don Buchla. When I brought them back to the shop, naturally I plugged the 101 in and attempted to get proper scaling and triggering sound out of it for 45 minutes, watching videos reading pointers etc. Finally I tried turning the 5 pin keyboard plug around, and then I lost 4 hours in seemingly 10 minutes. I was floored. I didn’t hook up the 200. The next day I delivered these to my friend and tech in Santa Ana. Within a week he had checked them out , addressed any issues and found them to be fully functional and in great working condition. So I picked them up and was really excited to try the 200. Got back to Fullerton and plugged it in with a mf-104 tailing into an early cooper cs-106+ and went to heaven. The spring sounded like the grampian, the preamp is also in that vein, dual ring modulators are very special. In particular as a studio piece the stereo functionality takes this to another level, signal processing to use while mixing or effecting tracks Is very much more than 1/2 the value with the 200. Awesome machines."

EML 101 and EML 200 Manuals

This one is in via Keith Soehn who had the following to say:

"As a former owner of 2 EML 101s, an EML 200 and the EML 400/401/416 Sequencer, I somehow felt the need to desktop publish the manuals for the above-mentioned EMLs. (I will also redo the EML 500.) It’s my belated thanks to all the people and to present and past users of these synths and sequencer. I enjoyed working with these units.

I presently have finished two manuals for the EML 101 and the EML 200, and I’m almost finished with the Sequencer manual. James Gideon has graciously posted the pdfs on his website at: https://siliconbreakdown.com/eml"

5/29/26 (goofy samba) EML 400/401 & 200 + Roland CR-78 + DSP 808 + Metasonix R-57 + ADE Panscan (…)

"5/29/26 (goofy samba) EML 400/401 & 200 + Roland CR-78 & SPH-323 + DSP 808 + Metasonix R-57 + ADR Pan Scan + Alesis MIDIVERB II

Whatever this is, it came about when I hooked up the Roland CR-78 drum machine trigger output (Disco 2/Samba) to the ElectroComp EML 400/401 external clock input. And it sounded so goofy I had to record it. A kick from the DSP 808 was added on the 1. The EML 400/401 is auto-panning through the ADR Pan Scan. Then I did an overdub, alternating octaves on the EML 400/401, with the CR-78 beat running through the Metasonix R-57, and a clave on the DSP 808. There is an additional clave sound towards the end, from the EML 200, using the envelope output from the EML 401. Reverb from the Alesis MIDIVERB II."

5/24/26 EML 200 + Metasonix TM-3 & TM-1 & TM-7 + Lower West Side Studios CGS01 + Alesis MIDIVERB II

video upload by Cfpp0

"The ElectroComp EML 200 master triangle is feeding the Lower West Side Studios CGS01 Sub Oscillator module, which is producing a sequence. The positive output of that sequence is modulating the Metasonix TM-3 gas-tube dual VCO, which runs through the Metasonix TM-1 SE waveshaper. The positive sequence from the CGS01 is also modulating the VCA input on the TM-1 SE. The negative output of the sequence from the CGS01 is sequencing the two VCOs on the EML 200, through its VCA, and with its internal spring reverb. The TM-1 SE audio output runs through the Metasonix TM-7 ultra-distortion scrotum smasher, which is being modulated by the EML 200 envelope output. From 1:49, the TM-3 suboctave and oscillator sync are creating some cool percussive spasms. Some reversed reverb is applied from the Alesis MIDIVERB II."

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."

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."
