6/4/25 ElectroComp EML 400/401 + Roland TR-909 + General Radio 1654-A + Alesis MIDIVERB II

"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

video upload by Cfpp0

"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

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.

"5/11/25 (Slope generator and sub oscillator sequence) SSL 1240 + LWSS CGS01 + Synthesizers.com Q123 & Q125 + muSonics Attenuators & Multiples & Wave Folder + Happy Nerding FM AID + Zerosum Inertia The Scorpion Tail + Blue Lantern Mixer + Alesis MIDIVERB II + ElectroComp EML 200

I spliced two takes one after the other. In the first, the 440 Hz tone from the Synthesizers.com Q123 Standards module, gated by the Blue Lantern mixer, is the constant bell-ish sound panned left. Throughout the whole video I am selecting divide or multiply on the Lower West Side Studios CGS01 Sub Oscillator, which varies the sequence. The Synthetic Sound Labs Dual Slope Generator bipolar output to CGS01 input A. CGS01 output A to .com Q123 to muSonics Multiples to Free State FX Macro Digital Oscillator V/OCT input and to Happy Nerding FM Aid CV input and to .com Q125, with Q125 output to muSonics Wave Folder CV input. Macro output to FM Aid carrier input. Macro sine out to muSonics Wave Folder to Multiples to Zerosum Inertia Scorpion Tail audio in and to Blue Lantern Mixer input 4, with spectral wave folder switched on, triggered by SSL 1240 fall gate out. CGS01 output B to CV in on Scorpion Tail. FM Aid saw out to Mackie Onyx 1640, panned right, with reverb from Alesis MIDIVERB II. Blue Lantern mixer VCA output to Mackie, panned left, with MIDIVERB II. Zerosum Inertia output panned center, dry. The drone is four VCOs on two EML 200, with internal spring reverb, modulated by their master sine waves."

5/3-5/25 (2 patterns) Simmons SDS6 & SDS1 + DR-55 clone + DigiTech HM4 + EML 200 + (in description)

video upload by Cfpp0

"5/3-5/25 (2 patterns) Simmons SDS6 & SDS1 ('flange snare') + Doctor 55 clone + DeltaLab Effectron II + TAMA DS200 + ElectroComp EML 200 + Ace Tone MP-4 + DigiTech HM4 Harmony Machine + Alesis MIDIVERB II + MXR 136 Dual Limiter + DBX 119 + Peavey 1300

This Simmons SDS6 was dead, but it’s been serviced by The Simmons Guy. It got converted from 220v to 115v with a rebuilt PSU, a cloned reset circuit on a custom PCB, traces rerouted on the dead expansion PCB with new caps and trimmer, new RAM ICs, new batteries, plus a MIDI in mod and, due to a lot of corrosion, plenty of new traces, caps, resistors, diodes, and so on. I’m still working my way through the SDS6 manual, but it’s already been a real pleasure to have such a giant sequencer. It makes the Doepfer Trigger Matrix seem microscopic. Considerable noise from the SDS6 is audible through the (always noisy) Doctor 55 clone. Not sure why. Anyways, the SDS6 is triggering the DR-55, which runs through the DeltaLab Effectron II, overloading the preamp limiter, fully wet, full feedback. In the first pattern, the Effectron II is set to Flange Lo (16ms). And then Double (64ms) in the second pattern. The SDS6 also triggers the SDS1, with a “flange Snare” EPROM and with the auto run feature on, and it’s panned a bit right with reverb from the Alesis MIDIVERB II. The SDS6 also triggers the TAMA DS200, which runs through the Ace Tone MP-4 for saturation and spring reverb. The DR-55 is also running through the Peavey 1300, which is panned left and has a lot of reverb from the MIDIVERB II. I did an overdub where I ran the whole first pattern through the DigiTech HM4 harmonizer, but the detuned copy sounded better when placed early, before the high pitched original. So if you are wondering why you can’t see those detuned notes on the SDS6 matrix, that’s why. You can see those notes being leveled by the MXR 136 limiter in the cutaway shots. The second pattern has drones from the EML 200 synthesizers: one is constant, panned left, and getting louder the whole time; the other is four VCOs through two VCAs, modulated by two different master sine waves, with the EML internal spring reverbs and reverb from the MIDIVERB II."

The pumping drone that sounds like a harmonium is the ElectroComp EML 200 through a 2hp Comp module, with reversed reverb from the Alesis MIDIVERB II and spring reverb from the Paia 6740. The bass pulse is the Metasonix D-2000, triggered by the MFB SEQ-1. The 16th note synth panned center is the Roland System 100m, sequenced by the RYK 185, through the Roland SPH-323 through the Peavey 1300. The 16th note synth line panned left is the EML 400/401. The percussion is the DSP 808 and the Soundforce S-LD, triggered by MFB SEQ-1 and ALM Pamela’s New Workout, which clocks everything."

4/22/25 Soundforce S-LD + SSL 1660 + GenRad 1564-A + BLM Gate Seq + DSP 808 + MIDIVERB II + PV 1300

video upload by Cfpp0

"4/22/25 ElectroComp EML 200 + Synthetic Sound Labs 1660 + Analog Craftsman acVOKs + STG muSonics Vanilla Envelope + General Radio 1564-A + Blue Lantern Gate Sequencer + Soundforce S-LD + DSP 808 + Alesis MIDIVERB II + Peavey 1300

Testing out a used Soundforce S-LD module we just got. You can hear the cowbell and the maraca (there’s a switch on the back to choose the Linn toms or percussion). The other percussion is from the DSP 808 module, which is a similar sampled sound module, but with pitch control and voltage controls. The synthy kick drum is the General Radio 1564-A processing the S-LD kick drum. Its VU meter looks like it’s out of sync, but it’s just slow and getting pinned hard. The two drones that build up are from two ElectroComp EML 200 synthesizers. The synth lines are Synthetic Sound Labs 1660 The Matrix Algorithmic Composer through the Analog Craftsman acVOKS filter into the STG muSonics Vanilla Envelope. The reverb is preset 10 on the Alesis MIDIVERB II."

Nothing drones quite like the ElectroComp EML 200. Two EML 200 VCOs are running through its left mixer into its internal spring reverb into its right mixer into the ADR Pan Scan and the Alesis MIDIVERB II and Eventide H3000B (Cyclons). The synth is the RYK 185 sequencing five VCOs through three filters on the Roland System 100m, processed by the Pan Scan, H3000B, and MIDIVERB II, with LFOs modulating the filters and with manual wiggling of the envelopes. The claves is the RYK 185 gate output triggering the DSP 808 module, with spring reverb from the Paia 6740. The tom is from the Roland TR-606, squashed by the MXR 136 limiter, with a room reverb on the MIDIVERB II. As the TR-606 kick drum is faded in, it further squashes the already squashed tom. The other kick is the DSP 808, with a trigger from ALM Pamela’s New Workout inverted by the Ladik U-202."
