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."

"The M0SS-201, M0SS-309 and M0SS-416 are 3 new members of the M0SS line of synthesizers from UltraPalace, expanding on the flagship M0SS-101 released in 2025.

This line of instruments packs the power of an advanced synth in to a tiny, rugged enclosure, and offers a unique user interface, designed to be intuitive, hands-on, and fun. Press a button to select a parameter in the synthesis engine, and turn the encoder to modify its value.

Coloured LEDs positioned across the face will pulse and toggle to show the signal flow, indicate settings, and show the current parameters magnitude.

These synths feature USB MIDI Host, as well as 1/8" MIDI, so you can connect any MIDI controller, and map knobs or faders to any parameter using MIDI learn, allowing you to transform your inexpensive MIDI controller into a powerful and fascinating vintage-style synth, or to integrate the synth into your existing MIDI setup.

On Kickstarter here: https://www.kickstarter.com/projects/...

"The M0SS-201 is a west coast synth, which takes some inspiration from the Buchla Easel. This modern monosynth is packed with features that will inspire experimentation into advanced synthesis. It is capable of an incredibly broad spectrum of sounds, and diving in, you might find yourself wondering if the sounds you are creating have ever been heard before by human ears, and the answer may well be no!"

Gene GX synth into effects = beautiful lofi atmosphere

video upload by Lo-Fi-Si

"Gene synths Gene GX
Walrus Audio Qi Etherealizer

Sending lofi fuzz and crackles into long delay and reverb with some granular sampling. The grains (at +2 octaves) create subtle trails as they feed into the reverb and delay.

I’m using the VCA Decay to adjust the keys from muffled plucks to longer chords.

The raw sounds of the GX are so interesting but I couldn’t resist exploring what happens when sending them into big effects.

To my ears it’s beautiful.

Serviced ARP Omni 2 Synthesizer with Synthchaser MIDI, LED Sliders & Road Case

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

via this eBay listing

"Here's a nice, restored ARP Omni 2... with MIDI!! This synthesizer has just been fully serviced by Synthchaser, the United States' top ARP specialist - recapped, new key bushings, new LED sliders, clean, fully functional, calibrated, in tune and sounding great. And best of all, this has been fitted with the Synthchaser MIDI Adapter! This keyboard is the sound of Joy Division and is all over The Cars' "Moving In Stereo", and many other late 70's/early 80's albums. It produces the lush Solina/String Ensemble sounds plus has a polyphonic synthesizer section with a voltage controlled filter, LFO, and ADSR, and a dedicated bass synthesizer section.

Excellent condition, with some marks on the right leather side panel. Includes a road case that needs new foam and to be aired out as it smells musty. See photos for condition. This synth was serviced by Synthchaser (the top ARP specialist) in February 2026. Work done included:

Synthchaser MIDI Adapter - Supports MIDI IN and THRU (only an "IN" jack has been fitted on this synthesizer). Configurable MIDI channel and starting key on your MIDI controller.

Synthchaser Precision LED slider upgrade. All 15 of the old original sliders have been replaced with new, smooth, high precision LED illuminated sliders (purple color--think Prince!). The difference in the way these sliders feel and perform compared to the originals is a huge improvement.

Power supply rebuilt - All tantalum and electrolytic capacitors in the power supply have been replaced, and high quality, high temperature 105 deg C capacitors have been used for the power supply filter capacitors.

All tantalum capacitors replaced - The tantalum capacitors in ARP synths are ticking time bombs. All of the over 100 tantalum capacitors in this synth, including the power supply and filter submodule, have been replaced with electrolytics to help provide stable operation for years to come.

Synthchaser 4075 Filter Enhancement Kit Installed - The ARP Omni uses the same 4075 filter submodule found in the Odyssey, Quadra, Avatar, and Pro DGX. This has been recapped, and enhanced to provide superior frequency response.

Keyboard rebuild - New key bushings installed, buss bar & key contacts cleaned and adjusted, keybed leveled, keys cleaned

Oscilloscope calibration - Fully calibrated to factory spec using oscilloscope and frequency counter."

MICROFREAK & PIGMENTS 7 DEMO

video upload by elz production

"Microfreak:
We can think of many reasons to freak over the MicroFreak. Yes, it is small, but it does offer some of the most unique sounds we’ve heard when it comes to budget synths.

If you’re new to the synth world, you really can’t go wrong with this instrument and it’s a great option with which to learn your skills. It’s well-built, comes with plenty of sound options, and the interface is intuitive.

Synths are evolving and growing in power every year. While some of us might love the crispness of an analog synth, as well as their bulky size, we still love the fact that you can have a powerful synth that can fit in a traveling case.

It makes us wonder about what the future holds for Arturia and the budget synth market in general.

Pigments 7:
Arturia have done it again. Pigments has grown in terms of features and become leaner and meaner under the hood, with those CPU and workflow improvements. It retains its place at the top table of software synthesizers, sitting alongside the likes of Omnisphere, Absynth 6 and UVI’s Falcon.

For the MPE enthusiasts amongst you, Pigments further cements its place as a showcase instrument for such endeavours. Pair it up with an Osmose, Rise or even Arturia’s own PolyBrute 12, and Pigments 7 becomes next-level superb.

If I had one quibble, it would be the lack of day-one support for AstroLab. They always seem to be playing catch-up, which will leave AstroLab owners slightly frustrated that they can’t take advantage of these new sounds straight away."

BÖHM SOLIST - 1972

video upload by Vintage Audio Institute Italia

"This unit is available for sale - if you're interested just shoot us an email at : Vintage dot Audio dot Institute @ gmail.com

Normally we focus on Italian gear but this is such a great little machine we thought we'd venture out a little.
This is the first model Bohm Solist - a mega-early, analog auto-accompaniment unit and drum machine from West Germany.
Comparing the two Bohm Solist models - the S and the 78 - we realized that they're almost identical. The only thing that's added to the next model are a few chord sounds and 4 added bass line variations.

You can watch our demonstration of the Solist 78 here : • Dr. Böhm Solist 78

The Solist machines are essential song-writing tools and offer some great, useful features : great drum sounds, chords and bass lines as well as an arpeggiator, all transposed by the control keyboard.

This video is not really a demonstration but a jam of sorts, with some help from external effects this unit sounds great and is a hoot to play.

Specifications :

The one-octave keyboard controller can only operate one finger at a time - it's not made to be played, but to indicate the desired key to the main, sound generating unit.

The major, minor and 7th and 9th chord options are engaged by pressing the grey side keys and the buttons on the right in tandem with the desired key.

Dr. Böhm named the auto-accompaniment section Böhmat - perhaps a mix of Böhm and Automat - and it has quite a lot going on considering for such an antique device:

1. A bass sound generator of bass lines spanning two bars.
2. 3 chord sounds with 6 rhythmic patterns
3. An arpeggiator figure and a Wah effect for the chords and arpeggiator.
4. Analog drum machine of 24 patterns that are mixable, mute options for most individual drum sounds.

The bass and chords rhythm patterns are unique to each rhythm engaged while the arpeggiator line is a single pattern for all.
The tempo of the Wah-Wah LFO effect follows the main tempo.

The drum section has 24 drum rhythm patterns that can all be played at the same time if one desires. There are mute options for all but a few drums sounds, as well as a snare roll and a single, hard-wired drum fill.

Make Noise Trio: 50 Combo Patches for Strega+0coast+0ctrl. No Talk Sound Demo. Live Jam/Performance

video upload by Anton Anru

"VOLTAGE IN SHADOW is a collection of 50 combo patches and patterns for a semi-modular system by Make Noise: 0-COAST + 0-CTRL + STREGA. It includes textures, basses, leads, drones, chords, percussion, and FXs.
💎 There is a wide range of timbres inside the pack: soft and bright, musical and experimental, harmonic and FX-like, cyclic and generative, slow and fast, analog- and digital-style, dry and atmospheric, clean and distorted.

📦 Get these patches: https://antonanru.sellfy.store/p/make...

🦠 This is one of the most complex works I’ve done. It required a lot of time and effort, but I also received huge pleasure and inspiration while working with such interesting and unique devices.
The patches turned out to be very fluid, dynamic, and non-static — largely due to the “alive” and sensitive nature of the synths. However, this also creates some difficulty when recreating the patches from images: even small changes in knob positions can affect the final result.

Erica Synths Steampipe + Torso S4 // DAY 17 #jamuary2026

video upload by Dexba

"Perfectionism almost killed this video, and for a second, I forgot about the point of #jamuary I recorded, and recorded, and re-recorded, and a few days have passed, back and forth, because I care so much about this sound, this vibe, this balance.
I am not 100% satisfied, but I have to let it go, because otherwise I know for sure I will start to hate these chords, I will have to tweak the sounds once again, I will change the video, and so on.
But I do love the resulting vibe, and I will try my best to bring variations on this theme in some live scenario, maybe with a different controller instead of the OPXY (which I am only using because it has midi via 3.5mm jack and... an audible metronome, I am looking at you, Torso)
I hope you'll like it, now this jam is free to run wild on the internet 🧡"

Fred's Lab Tooro Custom Patches [Bank 1] by synth_nyc

via synth_nyc

"I’m pleased to inform you that Fred’s Lab just released my 50 Tooro Custom Patches [Bank 1]. You can listen to them in high resolution (24bit 96kHz PCM WAV masters, FLAC encoded) on my site (optimized for Chrome on MacOS and Windows):
https://synthnyc.com/index.php/album/freds-lab-tooro-custom-patches-bank-1/

or in low resolution on my bandcamp:
https://synthnyc.bandcamp.com/album/freds-lab-tooro-custom-patches-bank-1

All recorded at 24bit 96kHz PCM on UAD Apollo X hardware with mostly UAD FX.

All patches have been created from scratch using my TouchOSC bidirectional editor for the Tooro: https://vimeo.com/1148477983

Most patches have MW, Velocity, AT and PB configured.

All patches have their volume normalized, so there is no audio jumping from going to one patch to the next.

All patches have been named, though you will need an editor that supports this Tooro feature, or you can simply see it using SYSEX Librarian.

As usual, I’ve tried to highlight what I think is unique about the Tooro. I particularly like the Shaper (analog) filter which I think blends beautifully with the digital oscillators.
Also the LFOs AM mode is quite interesting when combined with a LFO Rise value.

This synth has a lot of (strong) character; like the Modal 002 and Super 6 to give an example of hybrid synths with (strong) character (IMHO); but sounds completely different.

I hope you’ll enjoy those 50 Tooro Custom Patches as much as I’ve enjoyed programming them.

They are available for purchase on Fred’s Lab website: https://fredslab.net/shop/shop-front.php"

20 Years Later: The Korg Radias Still Sounds Incredible! Preset Demo |No Talking|

video upload by Davide Puxeddu

"In this video I play a curated selection of presets, showing why this synth still sounds fresh, wide, and inspiring even after 20 years.
Expect lush pads, deep basses, evolving textures and signature arpeggiators that defined the early 2000s Korg sound.

🎧 Best experienced on headphones – everything you hear comes straight from the Radias, no external effects or EQ.

✨ About the Korg Radias
Released in 2006, the Radias combines virtual-analog oscillators, formant motion sequencing and an advanced vocoder, making it a true hybrid instrument that still rivals many modern synths today."

UDO DMNO - It's bad

video upload by Noir Et Blanc Vie - After Hours

"Subjective opinions within, those who do not understand subjective opinion may be excused lol

Boring NAMM 2026 Noir here again lol
DUH, it's bad ass, OBVIOUSLY, the UDO team are kings of giving us classssssy old school sounds, amazing futuristic soundscapes all while putting it inside a gorgeuos box, imagine being able to get down on something that feels as good as it looks. See people as a musician, sound isn't everything, it's playability, it's easy of use, it's also is something inspirational. The DMNO is every single one of those things. Synths have gone stale, it honestly sucks, I'm not a synth crazy person, I'm a musician who loves cool instruments, getting excited has been real hard the last few years, hence why I've been playing shows and making albums way more. Can't be stuck inside playing the same ole thing companies think is 'groundbreaking, you should be excited' UDO is the truth, and they did it again. This is truly the new Cream Dream."

Ambient Electronica of Fading Synths and Sapporo soundscape | Fading Memories 2026-01-22 by atnr

video upload by atnr

"This piece was created using the ‪@SequentialLLC‬ Prophet-10, ‪@MoogSynthesizers‬ Moog One, ‪@YamahaSynthsOfficial‬ CP88, ‪@NordKeyboards‬ Nord Lead, and tape loops. Set against field recordings captured in snowy streets of Sapporo, electric piano and synthesizer sounds emerge and fade away, forming an ambient electronica composition.

The Prophet-10 is used to play synth pads, processed with reverb and delay via ‪@ChaseBlissAudio‬ LOST+FOUND.

Two tape loops are used. One contains a one-minute recording of an electric piano performance, while the other plays field recordings from the streets of Sapporo. The electric piano tape is played back on a ‪@WeAreRewind1‬ cassette player and processed with delay using ‪@strymon‬ TIMELINE. The field recording tape is played on a Rock & Play cassette player, with the pitch lowered and further processed through ‪@ChaseBlissAudio‬ MOOD MKII, where reverb and layered micro-loops deepen the pitch and texture.

The Moog One and Nord Lead are occasionally played to add synth pads. The Nord Lead is processed with reverb via ‪@gfisys‬ Specular Tempus.

The CP88 plays a Rhodes sound, layering simple phrases with its built-in reverb and delay."
