MARS Vacuum-Tube Synthesizer: The Most Aggressive Modern Synth I've Ever Tested

"What happens when you build a vacuum tube-based hybrid synthesizer in a Soviet space lab and send it back from the future? Today we’re demoing, reviewing, and explaining MARS from Eternal Engine Electronic Musical Instruments — one of the strangest, most beautiful, and most aggressive modern synthesizers I’ve ever played.

MARS is often described as a four-voice polyphonic tube synthesizer, but architecturally it’s more accurately a paraphonic synthesizer. The four digital oscillator voices can be played across multiple notes, but they all share the same tube-based filter and vactrol-based amplifier. That puts MARS more in the tradition of instruments like the Korg Mono/Poly and Formanta Polivoks than a conventional analog polysynth.

In this video, I walk through the full architecture of the Eternal Engine MARS: the digital oscillator section, mono / duo / poly voice modes, pulse-width modulation, ensemble mode, FM synthesis, modulation matrix, envelopes, LFO, sample & hold, the gorgeous Nixie lamp interface, the resonant vacuum tube filter, and the asymmetric tube overdrive that gives this synth its raw, snarling character.

This is not a safe, polite, modern analog synth. MARS is boutique, unusual, heavy, beautifully built, and absolutely vicious when pushed. The tube filter and drive section give it a sound that feels alive in a way most modern synthesizers don’t — somewhere between vintage analog synth, industrial bass machine, experimental sound design box, and Soviet sci-fi artifact.

If you’re into industrial music, EBM, darkwave, synthwave, experimental electronic music, vintage synthesizers, boutique synths, tube distortion, paraphonic synthesis, analog filters, FM basses, PWM pads, or Polivoks-style aggression, MARS is worth hearing.

I also talk through who I think this synth is actually for — and who should probably pass on it. Because while I absolutely adore the sound, MARS is not a cheap “do everything” synth, and it’s not trying to compete with mass-market analog polysynths. It’s a character instrument. A monster. A special machine for people who want something truly different."

Korg Multi/Poly Sound Demo | Pure Factory Presets (No Talking / Playing Only)

video upload by Davide Puxeddu

"Pure sound test of the new Korg Multi/Poly.
No talking, just music. In this video, we explore the potential of this synthesizer through a selection of its best factory presets.

The Multi/Poly takes analog modeling to a new level, merging the DNA of the legendary Mono/Poly with 60 voices of polyphony, 4 complex oscillators, classic filters, the endless modulation possibilities and Kaoss Physics.

🎧 To appreciate every timbral detail and the stereo dynamics, listening with high-quality headphones or studio monitors is highly recommended.

The audio is recorded via direct input through Antelope Orion 32 Gen 4 converters. No compression, EQ, or external effects were added in post-production. What you hear is 100% the raw sound engine of the synth.

Thanks to Algam Eko for lending me this monster for this video.

"This collection of vintage synthesizers has grown with me for years. Most all of these instruments have been used on many projects, including VeggieTales, a variety of remixes, and many PlayStation video games and marketing and promotional discs. Most recently they were used on the Mass Effect Andromeda video games soundtrack. They have also been sampled and are part of the SoundVault Collection and the Kurzweil Analog Collection for the K2000 series samplers.
VEMIA note: to forestall many inquiries, The seller’s idea is that he wants to sell it as a whole. That may or may not work out in this auction. If it doesn’t, obviously he’ll be free to do whatever he wants after the auction finishes.

It all works. Everything has been kept in a clean, smoke-free, climate-controlled studio. I have always fixed things myself, so everything is operational and sounding great. I have repair notes on the synths that received attention, though most of them have worked great over the years, without much need for repairs. There are also several MIDI to CV converters so they can all be controlled by computer, plus cables if desired. And a few have cases and manuals.

RetroSound Studio Tour: Analog Polyphonic Synthesizers

video upload by RetroSound

"RetroSound Studio Tour
Classic Analog Polyphonic Synthesizers from the 1970s and 1980s

In this episode of RetroSound Studio Tour, I explore the sound, design, and history of legendary analog polyphonic synthesizers from the golden era of electronic music. These vintage poly synths defined the lush pads, warm brass sounds, and cinematic textures heard in synth-pop, progressive rock, disco, film scores, and early electronic music.

This studio tour focuses on true analog polyphonic instruments featuring multiple voices, voltage-controlled oscillators , classic analog filters , and rich modulation systems. Unlike monophonic synths, polyphonic synthesizers allow full chords and layered harmonic textures — making them essential in 1970s and 1980s music production.

Exploring OXI ONE: Lazy Ambient Jam w. Moog Messenger, Vermona Perfourmer, Prophet 12 & Eventide

video upload by copenhagennoiselab

"'Sunday Excursion' is a relaxed ambient jam built entirely around two sequences from the OXI ONE.
No composition. No arrangement. Just hands-on exploration and letting the hardware talk.

🔁 SEQUENCING

The OXI ONE runs two independent sequences:

Sequence 1 – Rhythm / Pulse
– Matriceal mode for controlled randomness
– Drives a Moog Messenger mono synth
– Acts as the rhythmic backbone of the piece

Signal chain:
Moog Messenger → Klark Teknik KT76 → Korg DL8000R → TC Electronic Fireworx

Sequence 2 – Melody / Texture
– Linear mono mode with probability-based notes
– Drives a Vermona Perfourmer in round-robin poly mode
– Each voice slightly different for subtle movement and width

FX:
Vermona Perfourmer → Eventide Eclipse

🎹 LIVE PLAYING

On top of the sequences, chords and textures are played live on a Dave Smith Instruments Prophet 12.
The patch is a slow, restrained pad with a simple overtone structure.

FX:
Prophet 12 → Eventide H9 (Blackhole)

This is not a 'track.'
It’s a documented session exploring how the OXI ONE interacts with a few quirky synths and late-90s / early-2000s rack FX.

If you’re into hardware sequencing, probability, and letting small variations do the work, you’ll probably find something useful here."

"We are thrilled to welcome synthesizer pioneer Dave Rossum to the Board of Directors of the Bob Moog Foundation, the governing body our organization. Many of you know of Dave from his early days at E-mu Systems, and his more recent work through Rossum Electro-Music, but his work extends far beyond the companies that he has created. Dave's work in SSM chip design can be heard in the Prophet 5, Korg Polysix, Korg Mono/Poly, Fairlight II, PPG Wave 2, and many others. He also invented the polyphonic synthesizer keyboard.

Dave brings with him a wealth of creative and business expertise that will help drive the work of the Bob Moog Foundation forward. You can read more HERE."

Minimoog Prototype Exhibit At the Moogseum This Weekend Only!

The anticipation is almost over! We are thrilled to be hosting the Minimoog Prototype Exhibit at the Moogseum, this weekend only, in partnership with the Museum of Music Technology (MMT). The exhibit will feature four ultra rare Minimoog prototypes from 1969, 1970, and 1971, as well as a host of related artifacts from the Bob Moog Foundation Archives.

We are honored to have JoE Silva, author of The Minimoog Book: The Synthesizer That Changed Music Forever: Sounds, Stories, and Technology join us throughout the weekend of the exhibit. He'll be on hand to delve into the history of the Minimoog with exhibit attendees and sign books in the Moogseum store.

We're excited to share a new addition to the exhibit. MMT will be bringing Minimoog serial number 1016 (the sixteenth Minimoog ever produced out of 12,269 units), which was purchased in 1971 by none other than David VanKoevering, the marketing genius behind the early Minimoog sales. David's Minimoog will be available for exhibit attendees to play and explore. Come get you hands on this incredible piece of synthesizer history!

Finally, be sure to take advantage of the morning tours with our executive director, Michelle Moog-Koussa. Michelle will be delving into Minimoog history as it is conveyed through the main gallery of the Moogseum. She doesn't give tours often, so take advantage of this opportunity. The tours are available for a small fee for any exhibit attendee.
