RMIF OPUS - Unique synth pulsations

video upload by LFOstore

"The RMIF Opus (РМИФ Oпус) is a rare analogue string machine/synthesizer made in Riga, Latvia by the Riga Musical Instrument Factory (RMIF) in the year 1988.

The sound range is five octaves and the instrument consists of 4 sections — piano, that synthesizes piano like lead soundings of different timbres, analog string machine, that plays wonderful string sounds with soft attack and with the possibility to control release, tremolo and the pereodically repeated beat-fading sounds.

A flexible bass section, that is controlled by 2 lower octaves, that contain three 8' and two 16' registers.

The Opus is based on divide-down technology with a master oscillator and has very nice multimode filter (LPF, BPF and HPF with resonance), a fantastic chorus, ring modulator, vibrato and a lot other features."

Deeply Flawed, Utterly Charming: RMIF TI-5 Synthesizer

video upload by HAINBACH

"The RMIF TI-5 "Digital Keyboard", an 8-Voice analog/digital hybrid synth, is little known, even in former Soviet countries. As they did on the ES-2-5 drum machine I covered here before, it seems that the engineers in Riga took a look at what Roland was doing, taking inspiration from the Juno-line. Unlike the famously sturdy Japanese instruments, the TI-5 was built rather haphazardly, with bad clones of western chips managing the voices and processing. That is why only few survived the test of time. Yet despite its shortcomings it sounds utterly charming, managing both deep Moog-basses, vast evolving pads and chiptune leads.

Alisa 1377 - Raw Sound Demo

video upload by LFOstore

"#alisa #1377 #alisa1377 #synth #demo
Rare USSR synthesizer restored by Alex Taber!

It was made in USSR in 1985 at Luberetskiy Military Radioplant "Rodina" near Moscow.

ALISA synthesizers were made especially for experimental electronic music, creating of sound effects in soviet cinema and scientific acoustic researches. This unique instrument has warm, aggressive and absolutely original analog sound!

The synthesizer has 1 OSC with 4 wave forms, ADSR , filter, various modulations, vibrato and portamento effects.

OSCILLATOR: tune; octave +1/+2; portamento; wave forms: triangle, saw, square, odd harmonics; frequency modulation (for all 4 waveforms); impulse-width modulation (for square wave form) with impulse width and depth controls; harmonics (for odd harmonics wave form). You can use individual OSC waveforms (triangle, saw, square, odd harmonics) or mix them together to get unique sounds!

LFO: on/off modulation switch, two waveforms (triangle, square), modulation rate, modulation rate coarse switch - 1Hz/10Hz.

FILTER: cutoff, resonance, vibrato (filter modulation), ADSR, switch between filter control- keyboard or contour OSC (ADSR). The synths filter due to it`s original architecture can be used as additional oscillator when filter`s resonance knob in self-oscillaltion position and it sounds really weird and interesting!

AMPLIFIER: ADSR, main volume, on/off synthesizer."

RetroSound Studio Tour: Analog Monophonic Synthesizers

video upload by RetroSound

"Welcome to RetroSound Studio Tour: Analog Monophonic Synthesizers & Duophonic — a deep dive into legendary mono synths from the 1970s and 1980s, including rare East-Bloc classics.

In this new episode, I showcase iconic instruments such as the Minimoog, ARP Odyssey, Roland SH-101, Maxi-Korg, Sequential Circuits Pro-One, alongside Soviet and East German synthesizers like the Polivoks, Alisa 1377 and Vermona mono synths.

These analog monophonic synthesizers defined the sound of electronic music — from the fat Moog and cutting ARP to aggressive Polivoks and raw Eastern European character.

This video explores the sound and architecture of true analog mono synths built around VCO, VCF, and VCA signal paths, highlighting their distinctive basslines, lead sounds, and modulation capabilities. From the Moog basslines to the aggressive Polivoks filter sound and the unique character of East German Vermona synthesizers, each instrument demonstrates why 1970s and 1980s monophonic synthesizers remain highly sought after by collectors, producers, and electronic music enthusiasts."

MARS Tube Synthesizer vs Ultrarare Formanta P432 VST Plugin

video upload by Eternal Engine EMI

"Our friends from UltraRare ( https://ultrarare.su ) have created a cool plugin: a VST version of the Soviet Formanta P432 synthesizer.
The plugin is a rompler with sounds from this Soviet synthesizer. One of the features of the software version is the ADSR envelope, which expands the instrument's sonic capabilities. The sound bank is controlled via MIDI, allowing users to freely switch between presets within a single part.
There's a lot more interesting stuff on the UltraRare page: https://ultrarare.su/?post_type=product"

You can find a demo of the hardware Yunost 70 here.

"UltraRare has released the Yunost 70, a Soviet-era electric organ manufactured between 1970 and 1973 using germanium transistors, the foundation of early electronics. This version of the plugin features note-tuning for all built-in oscillators and an additional one, created using a recording of the instrument's built-in speaker on a reel-to-reel tape recorder, a microphone, and tape, also from the 1970s.

Nick Klimenko - Synthesizer Museum Live (full album)

video upload by LFOstore

"LISTEN: https://cosmicleaf.gr/releases/1136/s...

Welcome to the 25th full-length album by Chronos. With this release, Nick Klimenko celebrates the opening of his personal synth museum!

In this unique space, you’ll find 190 hardware and 160 virtual instruments spanning the years 1978–2025. Chronos returns with a third live-played album, exploring the full depth of both analog and digital synthesizers. Everything was performed and recorded live in one take, inside the new museum space - https://nksynthmuseum.com/en/

Nick devoted countless hours practicing live playing, sequencing patterns and harmonies, and shaping rhythms and atmospheres for every single piece on this release.

When the time came, he simply hit the 'record' button — and played each track straight through.
This approach echoes the spirit of the 1970s, when Klaus Schulze and Tangerine Dream performed concerts entirely without computers or music software.

Musically, this album overflows with ambient and cosmic atmospheres, cinematic movements, and unique soundscapes

Tracklist:
001. Chronos - Soviet Analog Synthesizer Ambient
002. Chronos - Silentium Universi
003. Chronos - Inner Odyssey
004. Chronos - Summer Trio
005. Chronos - Alien Lights Above My Head

Monolit + Aelita //

video upload by Sasha DZA

"Aelita is a Soviet analog monophonic synthesizer from the late 1980s. Simple in architecture, it is known for its raw, unstable tone and distinctive analog drift, valued for character rather than precision.

Paired with Monolit, Aelita gains entirely new possibilities. Precise MIDI automation, sequencing, LFOs, and probability-based control extend far beyond its original interface, transforming a classic Soviet instrument into a flexible and contemporary sound source for studio and live performance."

Alisa 1377: The Rare Soviet Synthesizer from the mid-80s

Rodina Alisa 1377 - Soviet Analog Synthesizer (1985)
The Alisa 1377 is a rare monophonic analog synthesizer built in the Soviet Union during the mid-1980s.
Manufactured at the Lyubertsy Military Radioplant 'Rodina' near Moscow.
A lead synthesizer intended not for mainstream pop, but for experimental electronic music, sound design, film work and research.
Produced in small numbers, making surviving the units rare.
The Alisa 1377 is fully analog. All waveforms can be used individually or in combination. Frequency modulation (FM) available for all waves.
Pulse width modulation (PWM) with adjustable width and depth.
Octave switches (+1 / +2) and portamento. The sound character is warm, raw and a bit instable. Unconventional compared to western synths. The self-oscillating filter and the FM options allow for metallic, droning, and very experimental tones.
