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.

If you're into rare, mostly Italian synths and drum machines you can subscribe to our channel and please check out our other videos of rare gems, but you might also enjoy the V.A.I. website : a photo book and encyclopedia Italian Vintage Synths and Drum Machines: https://www.vintageaudioinstitute.com/"

A COMPACT ANALOG COMPRESSOR

Messor is a fully analog stereo feed-forward VCA compressor designed for studio, modular, and live systems. The architecture is derived from the original Cosmotronic eurorack module, with extended headroom, improved channel matching, and a revised sidechain topology optimized for wide dynamic ranges.

HIGH HEADROOM

The internal ±12 V regulated power rail provides substantial headroom and consistent operating conditions for both line-level and modular-level sources. It reliably handles high-transient material from synthesizers, drum machines, and percussion-heavy sources without premature clipping. High-impedance inputs and balanced outputs simplify interfacing with modular systems, samplers, and balanced studio equipment.

Signal flow begins with a low-noise stereo preamplifier offering up to 18 dB of gain, followed by a pair of matched VCA control blocks. The feed-forward topology provides predictable transient behavior, accurate envelope shaping, and stable stereo imaging. A post-VCA conditioning stage adds tube-like saturation, introducing controlled harmonic content when driven into overload.

Industrial experiment with Hexdrums, Xenodrive & the Echolocator

video upload by Richard DeHove

"This is an experiment. It started with the thought: "What if I took just two voices from Hexdrums and feed them as individual outs left and right into the Xenodrive?". That felt a little raw even for me so I then added the Echolocator after the Xeno. After hooking it up I had a joyous 30-minute "jazz odyssey" of which this is the still-very-long-for-pure-drums cutdown version.

All three machines are tweaked as a single control surface and I don't think any machine here is the star. They all do their bit. Since there's no unaffected sound keeping things stable the Xeno work is quite restrained compared with the complete destruction of which it's capable, and likewise the Echolocator stays reasonably tame.

Was there a lesson from all this? Perhaps it's just that trying odd combinations is fun. On a more practical level I can certainly see that various sections could be usefully sampled as loops. To that end I've put together a pack of 16bit 44KHz loops at 110bpm that are on my Patreon page. Many of them can be usefully split left and right for further processing.

As usual there is no DAW processing and the volume has all the ups and downs of the original.

Behringer BMX - What the F...lol

video upload by Noir Et Blanc Vie - After Hours

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

So the Behringer BMX, honestly, do you really care what I think? WELL, here's my thoughts, it's IMPOSSIBLE to freaking use something like this on the floor of a convention without help and NOBODY was trying to help me haha. That said, sound wise, oh for sure, it's solid, 100%. Dare I say "good", BUT, dang, everything is good these days. Gear is just a tool, but I think this could be useful, more useful than the Linn from the B. Would I buy the BMX, absolutely not, never hahaha. That's becasue I'm FLUSH with drum machines, and straight up, if I'm working with an artist or my own albums for drums specifically I'm ITB. Tempest is still the absolute king, if you have a TR-8s, Tempest, uhhh, Drumlogue, Alphabase, I mean geez a number of other drum machines you're good, you don't need to buy more space fillter, you can make music without this, TRUST me. BUT, it does sound good, the bass drum is no Alphabase though, no freakin way.

A Love Story - Roland Cloud CR-78 First Look

video upload by Starsky Carr

"The Roland CR-78 CompuRhythm is one of the most iconic drum machines ever made — and now it’s back as a stunningly accurate ACB emulation inside Roland Cloud. In this video I take a deep dive into the CR-78 plugin, exploring its legendary analog sound, programmable patterns, classic rhythms, and all the powerful new features that go far beyond the original 1978 hardware.

The original CR-78 was the world’s first programmable drum machine and became famous for its warm analog voices, signature presets and musical groove. It appeared on countless classic records — from Phil Collins and Blondie to early synth-pop, post-punk and electronic pioneers.

In this demo I explore:

Roland’s ACB (Analog Circuit Behaviour) modelling technology

How the CR-78 patterns, fills and variations work

Sound shaping with decay, tuning, gain and metallic tone

MIDI CC control and DAW automation

Live performance workflow and pattern programming

Why this is so much more than just a retro drum machine

If you love vintage drum machines, classic analog rhythms, synthwave, post-punk, electronic music production or hardware-accurate software instruments, this is one you don’t want to miss.

🎛 Classic analog warmth
🥁 Programmable rhythms & fills
🎚 Deep sound design
🎹 Full MIDI control
🔥 Perfect for synthwave, electro, indie, pop & film scoring

The CR-78 may look simple — but it’s a seriously powerful creative tool once you start digging in."

Alchemist is now EURORACK... into the CITADEL!!!!!
So here we go checking out how this synth engine will play out with his other citadel friend the Wave Bard in breakbeat torture mode.
Also a cool oportunity to play around the Diktaat from Mzourack to trigger both units in a performative way.

Citadel Alchemist is a patchable hybrid-synthesis based eurorack module that empowers you in discovering melodies and even harmonies despite being monophonic.
Patch programmable sequencing via the control signals into the two PITCH MOD inputs opens up a world of melodic inspiration beyond classic arpeggios while staying in your preferred SCALE.

5 synthesis modes
The Alchemist has a carefully tuned wide timbral range spanning across 5 synthesis modes (FILTER, FM, HYPERSINE, SUPERSAW and GLITCHNOISE) accessed by main TIMBRE sweep that is refined by the RATIO control.

The ENV macro knob affects different parts of the synth and sequencing engine to maximize musicality and it even lets you continually morph between the synthesis modes and access truly unique sounds.
The timbral palette is further extended by the dual FX section which offers either a wide delay that will smear the arpeggios into echoed harmonies or a chorus-flanger-distortion-combfilter macro custom tuned for each synth mode.
You can also access gliding rubber textures with the PITCH SLIDE macro that applies pitch envelope and portamento.
You can customize its rhythms and scales with the web-based editor.
Modulate anything
All main parameters can be modulated and tightly sequenced by the surprisingly powerful CV and GATE pattern generator. Create groovy off-grid beats using the built-in LFO, which can be synced, reset, or left to run freely.

Diverse moods of Leviasynth / by Jexus.

video upload by Jexus (sounds-for-synths.com)

"In 2025 Ashun Sound Machines contacted me and asked if I would like to create a set of unique presets for their upcoming synth. No details were disclosed about the instrument but, as you can imagine, I was curious. I agreed and several weeks later a monster 8-oscillator synth arrived at my doorstep. Today all of you can see it and hear it in action - the LEVIASYNTH is ready! Here's a quick video with some factory presets I created on the new Leviasynth. In this demo I kept the internal reverb low and did a fair amount of tweaking to give you a better idea of the timbre / behavior of the synth.

ASM Leviasynth | Sounds and Key Features | Synth Universe

video upload by Synth Universe

"A musical exploration of Leviasynth, Ashun Sound Machines’ successor to the Hydrasynth. Leviasynth is an 8 oscillator algorithmic synthesizer with analog and digital filters and five types of synthesis.

All the sounds featured in this video were created by me and are included in the Leviasynth factory presets (except Synfluctuate and PD keys which may be released by ASM as part of future banks). If you own or try out a Leviasynth, you can browse patches by sound designer and select Synth Universe to find all my sounds. Here I have often emphasized sounds that make use of the analog filter, showing the ability of Leviasynth to emulate analog synths, as this is one of the first things I want to know when assessing a hybrid synth. I also feature patches that highlight the other types of synthesis including FM and phase distortion.

This is a deep and powerful ‘monster’ of a synth and so far I have really only scratched the surface of its capabilities. There are too many features to list here so go to Ashun Sound Machines website to find out more.

Disclaimer: ASM sent me a pre-production unit for the purposes of sound design, but otherwise they had no input into the making of this video or the opinions expressed within.

No external enhancement or processing was applied to the sounds in this video: you are hearing them as output directly from the synth.

Note: Leviasynth does have a powerful arpeggiator and sequencer, but as they were still being finalized during the time I created these patches they are not featured in this video."

ASM LEVIASYNTH Review // Keyboard vs Desktop vs Hydrasynth

video upload by loopop

Details:


From the darkest recesses of the unexplored oceans comes ASM's most powerful creation yet—a hybrid algorithmic synthesizer with sixteen-voice polyphony, eight oscillators per-voice, and a truly absurd amount of sound design potential. There are over 300 waveforms available for each voice's eight oscillator slots, giving you access to a bonafide sandbox of sonic alchemy. Each voice's oscillators can be arranged and rearranged for versatile modulation schemes using the many available algorithms. This open-ended method of crafting timbres gives you nearly-unlimited possibilities for sculpting sounds ranging from familiar tones to completely alien timbres. In addition to the ability to create your own algorithm, the Leviasynth also comes with 144 preset algorithms for quick sparks of inspiration, and the ability to morph between these oscillators non-linearly.

The oscillators can be modulated in a multitude of ways to create even more timbral variation: Frequency Modulation, Phase Modulation, Pulse Width Modulation, HTE Sync, and Phase Distortion can all be applied to Leviasynth's oscillators for nearly-endless sound design potential. These, along with nearly every other parameter, can be affected using the internal 32-slot modulation matrix. Each of the eight oscillators includes its own volume envelope, along with five additional shared envelopes and five LFOs per-voice for creating a moving sonic texture within the canvas of the expansive modulation matrix.

The Leviasynth is one of ASM's most expressive synthesizers to date, offering a 61-key keybed with full polyphonic aftertouch, MPE compatibility, and a four-octave ribbon controller for even deeper playability. Record and playback more than just audio with the internal three-track sequencer, allowing you to record note, arpeggio, and macro automation data. Control a plethora of parameters across the synth with the eight individual macro controls, which provide a deep level of expressivity given the broad timbral potential of Leviasynth's multi-algorithm design. Expand this expressiveness into your Eurorack systems with the 3.5mm CV I/O, providing two assignable Mod inputs, as well as outputs for Pitch, Gate, Clock, and two assignable Mod outputs.

Leviasynth offers both analog and digital filters for sculpting multi-layered timbres. On the analog side, you get a buttery-smooth four-pole low pass, which provides the foundation for beautiful, intimate sounding patches. On the digital-end of the spectrum there is a complex, Hydrasynth-style multimode filter with eighteen different filter types. All of these filters can self-oscillate at high resonance settings, along with pre-drive saturation for helping your patches cut through any mix. The effects section offers two independent methods for applying that extra layer of polish to your sound. In the master effects, you can shape and transform your final sound with Delay, Reverb, Distortion, Rotary, Phaser, Chorus, Compression, EQ and more. The second method provides dedicated insert effects, which offer five flavors of Delay and four Reverbs for giving your sounds that ever-important sense of space. This two-layered approach to effects gives the Leviasynth a sound all its own, and when used in tandem with the aforementioned suite of timbral shaping engines, your imagination is the only limit. Like the vast unexplored waters of the deepest oceans, the ASM Leviasynth holds an immense amount of undiscovered potential underneath its dormant surface.

CRUMAR CORDATRON (1974) Castelfidardo

This is an accordion string machine with organ section, a brass synth section with filter controls, trigger-able analog drum sounds and chord and piano presets on a Stradella button board.
Crumar made a few different models of this type of instrument but this is the very first.
Unicorn rarity is the order of the day regarding the control key- and button board - the serial number 3 of allegedly 10 units ever put in production.

Crumar had just started producing keyboards after mainly producing accordions, and around this time they launched the three COMPAC models that definitely inspired the sections of the Cordatron: Compac Strings, Compac Brass and Compac Piano.

Most of the CRUMAR CORDATRON specifications are in the video as text already so please watch the video and read the text - but a quick roundup would look like this :

The instrument consists of mainly two separate units connected by a huge, hardwired 3-piece connector : the main sound generator unit with power supply, audio outputs, tuning and volume pedal, as well as the control unit - basically a butterflied accordion with a Stradella button board for the left hand and a regular keyboard for the right hand.

All the sounds are analog and are generated by the very first generation of divide down technology - no eproms or other intruders of vulgar modernity is on hand.
The sound generator weighs 23 kilos and is literally crammed with sandwiched layers of massive circuit boards of transistors and capacitors.

Rise Me 🌅 (Arturia Minifreak // Roland J6 Chord Synth + H90 with new granular effect // TR6S)

video upload by 2-Minute Warning

"Happy New Year my friends! 🎹🔊
May 2026 bring you endless jams, wild synth waves, and machines that push the limits of what's possible. Thanks for jamming with me—here's to more electronic adventures ahead!

For this first jam of 2026, after having used the Arturia Minifreak as only instrument in my 2 last videos, I wanted to try it with a couple of other instruments. In this jam, only the DRUMS (TR-6S) have been sequenced, I'm playing the BASS (Minifreak) and CHORDS (J-6) in real-time 😉

The jam starts with me triggering some CHORDS on the J-6 and adding the cool new granular effect (Grainmod) from the Eventide H90 pedal.
I then fade in the DRUMS and finally play the BASS in real-time.
I'm using the AUTO FILL feature of the TR-6S so that there's a break at the end of each 8-measure.

** Hardware used **

// 🥁 DRUMS:
Roland TR-6S (Digital Rhythm Performer)


// 🎸 BASS:
Arturia Minifreak (polyphonic hybrid keyboard with dual digital sound engines and analog filters)

// 🎹 PADS:
Roland J-6 (Chord sequencer with the tones of the renowned JUNO-60 synth)"

Sounds Like the 80s and 90s (In the Best Way) // Waldorf Protein

video upload by Starsky Carr

"Discover the gritty soul of classic wavetable synthesis in this in-depth review and sound demo of the Waldorf Protein. Drawing direct lineage from the legendary PPG and *Waldorf Microwave*, the Protein combines authentic 8-bit, 128-sample wavetables with a modern, streamlined workflow — delivering that unmistakable lo-fi digital bite without the complexity of vintage machines.

In this video, I explore how the Protein’s 8-voice / 4-part multitimbral engine lets a single patch handle basslines, arpeggios, leads and textures simultaneously. You’ll hear how the stepped wavetable movement, classic aliasing artefacts and digital filters create tones that newer, smoother wavetable synths simply can’t replicate.

I also break down:
• How classic PPG-style wavetables actually work
• Why 8-bit waves sound so alive and musical
• Digital filters, drive modes & modulation
• Multitimbral layering for complete tracks
• Why this isn’t a Microwave clone — but something new

Whether you’re into *90s trance, industrial, ambient, IDM, synthwave, techno, or just love characterful digital hardware*, the Waldorf Protein offers a uniquely inspiring take on modern wavetable synthesis."

KIVIAK WoFi - "Fierceful Sequential Machines"

video upload by Alba Ecstasy

"Hi! The team from KIVIAK Instruments sent me the WoFi right before the Christmas.
And since then, there hasn't been a day that I haven't played the WoFi!

I’m not mastering it at it’s very best, yet! - but this sampler has a HUGE POTENTIAL!

From the very first day I sampled my voice, my kids' singing, my synths, ambiental noises and anything you can think of!

Diving into the samples with the Waveform Viewer, using the Touch Stripe or the Texturer’s buttons, to create new interesting sounds and modulate them with the LFO, to obtain either an industrial, harsh sounds or a sound with vintage lo-fi vibe.

Here’s a sample from my Sequential PRO 3, using it to create a Berlin School sequence on my own style with a vintage vibe, and playing over it - by using the SOLO function - a plucky/organ lead, both the sequence and the lead using the same sample.

I’m passing through the sampling MACHINES and the Playback Modes and tweaking some functions.

I added some delay and reverb, and during the playing (made in post processing) I’m bypassing them for a raw sound."

More to come, next days!
