ADDAC Perc VCA and Friends Jam
video upload by Molten Music Technology
"Really liking the Perc VCA for the simplicity of its built in decay envelope and ability to grab a bassline with the minimum of fuss. Here's a quick demo and I hope to do a full review soon."
"While deep in its soul there’s a standard VCA with exponential response that can be used as such, in its heart pulses an AD envelope with a sharp attack and a variable decay internally connected to the VCA control input. When it opens its mouth it can whisper in your ear but don’t let this soft demeanor fool you, if driven to the extreme it will show its teeth and gnarly bite and chew on your cochleas with all its might.
The AD envelope has a fixed short Attack, just enough to avoid the typical “click” that happens when using a Gate signal to control a VCA, while the envelope Decay can be controlled via its knob or voltage controlled using the CV input and attenuverter.
We named it Percussion VCA as most percussion intruments have sharp attacks with variable decays just as its AD Envelope however it can be used for any purpose where a VCA is needed including for CV signals due to it’s DC coupled signal path.
Furthermore it also allows to be driven from a simple Gate signal while controlling its decay. This way it’s easy to plug a noise source, vco or any audio and turn that source into a percussive element."

Antonus 2600 DIY - Test Drive
video upload by Tumeni Knobs
"This is my Antonus 2600 - I just completed building it from the synthCube.com full DIY kit. It is a huge project! Working on it in my free time, it took six months for me to complete. But I'm sure a full-time builder could do it in a couple of weeks. I actually love that it took me this long. :-)
Anyway, since I first powered it up I have been testing, calibrating and starting to understand how it works, and yes, it deserves it's reputation as an awesome sounding and very flexible synthesizer.
This video is just me noodling on it using the Arturia KeyStep Pro with a sound/patch I really like. This is actually just one of its three oscillators, but I have the saw and square waves patched in. The other two oscillators are in LFO mode. The oscillator is using the ADSR envelope and the filter is using the AR envelope plus an LFO to modulate it - makes some interesting accents.
Effects are courtesy of the Fractal Audio VP4, which is an incredible pedal.
I thought adding some drums would give this more of a musical context, so I force-fit some patterns from EZ Drummer.
The opening groove is definitely reminiscent of Bluetech's Laika, from the Spacehop Chronicles album. It's intentional. :-) I really like his stuff! Go buy some at Bandcamp.
This signal path for this recording goes like this: 2600 into VP4 into iRig into iPhone. I then applied a little EQ in Studio One, just to trim out the extreme highs and lows - I did not use any compression on this.
Can't wait to make some "proper" music with this amazing synth.
Cheers!"

Explore the modular’s re-patching power
video upload by Monotrail Tech Talk
"With a modular you have full control over your signal path. This means you can combine modules and functions like oscillators, VCAs, and modulation sources in different ways, again and again. In this video I show how the ingredients for a ‘classic’ 2 oscillator voice can be expanded, and used to create a variety of interesting ‘simple’ dual voice setups."

Synthesizer-Wettbewerb, Beitrag "Ambient Jam"
video upload by KEYBOARDS
"Ambient Jam with Polyend/Dreadbox Medusa and a few iPad apps.
A total of only 6 tracks, a simple chord progression, but with Probability/Random Notes from the Medusa and a few effects. It's all very chilled out and only using my "desktop setup" in my office. Since I usually only make music with hardware, this is a nice change and a challenge for me.
To visualize the whole thing more appealingly, I used a freely available NASA video in the background, which can be used for non-commercial purposes. The video was created with Adobe Premiere Pro. Everything else in the video, and of course the music, is mine.
I use the Medusa with Probability for melodic to whiny synth sounds, mostly with the wavetable oscillators. During recording, I play around with the filters and oscillators. The Medusa sequencer is synced to AUM by Kymatica.
I also recorded the bass beforehand using the Medusa and its analog oscillators. This is played back via the Koala sampler.
The track begins with a synth pad from Synthscraper/Igor Vasiliev
and two tracks of 'synthetic' water (one via the Koala Sampler, the other via the Spacecraft granular sampler). I tinkered around until I managed to create something reminiscent of flowing water from the noise and other sounds.
Klevgrand's Hillman, a phaser-equipped organ synth, is used to give the track a bit of a retro flair.
To increase the dynamics, Klevgrand's REAMP, a tube amp simulation, is later used.
Reverb from Eventide (BlackHole) was used except on the bass.
The mastering was done with GrandFinale 2, which was already in the signal path during recording."

A "Little Synth" Designed by Legends
Crumar S.P.A., based in Castelfidardo, Italy, was a notable player in the 1970s musical instrument industry, specializing in home organs, digital pianos, and multi-sound keyboards, and with a significant focus on the U.S. market. Sante Crucianelli, the son of the owner, became the driving force behind Crumar's design and strategies. Crumar became known for its open lab culture, frequently allowing competitors to test instruments, a rare practice for the time. Another key figure during this period was Luciano Jura, a designer, musician, and programmer. Luciano became crucial as Crumar's point of contact with synth pioneer Bob Moog, which led to a collaboration that resulted in the creation of Crumar's Spirit synthesizer.
Although many details have been lost due to the passing of key figures and the closure of Crumar, the development of the Spirit synthesizer in the U.S. is well documented. Key contributors to the project, codenamed "Little Synth," included Moog engineer Jim Scott, Moog clinician and electronic music historian Tom Rhea, and Bob Moog himself. The project likely began around 1980 or 1981, and incorporated elements from earlier projects by Scott and Moog. Rhea played an essential role in defining the Spirit's key features, such as the keyboard scanning setup, panel layout, functional architecture, and technical documentation. The Crumar Spirit went into production and was released in late 1983.

POLYGENE II - First Look
video upload by LA Priest
"Sound recorded directly from the back of the synth (No added effects / eq / reverb etc)."

"POLYGENE II is an all analog polyphonic synthesizer with two halves. One half is all-transistor class A from signal source through audio path two output, the other half is identical except it uses analog chips to generate dynamic customisable waveforms.
Inspired by the earliest polysynths of the 1970s, it is fully polyphonic (all 24 notes can be played at the same time), can be tuned to any scale or tuning, is multi-timbral and completely touch sensitive.
Touching any part of the synthesizer bridges connections in the circuitry and creates a unique sound.

GS Music Bree6 // Small Simple and Sublime
video upload by Starsky Carr
https://www.gsmusic.com/
"Sound is everything... and the GS MUSIC Bree6 doesn't fail to deliver. There's an intangible quality to the tone of their synths. The GS MUSIC e7 bing their first offering, that bowled me off my feet when I first got my hands on it.
This was first announced in NAMM 2024, so it's took a while to get to me - and it was worth the wait. Its a single VCO 6 voice polysynth with a 24dB LP filter and all analog signal path ... so it's in the same ball park as Juno's except this is a VCO, not a DCO, and has a different flavour.
Importantly for a boutique synth manufacturer, this feels great to use - its got a knob per function interface thats so intuitive and easy to navigate you'll be an expert in minutes!"

Telmatronics Groovetube - comparing line-in/output signals
video upload by Telmatronics
"This video shows our completed machine, running second-version pcb.
It is essentially a 2-channel valve pre-amp with plasma tube in the current path. One channel is used for the synth voice, one for line-in.
We've got a good sound putting audio through a Wingie2 resonator before sending to the synth line-in. This boosts certain frequencies of the input, which puts some initial distortion onto the signal.
For these clips the input signal was split before the line-in, and routed into a separate mixer channel to the synth. Turning them up in turn lets you hear what the resonator is doing, and what the synth is."

Pure Analog Polyphony with the VAEMI Modular System #eurorack #osiop #xfmr #vca #subtractive #synth
video upload by Vaemi
"Pure Analog Polyphony with the VAEMI Modular System
Most polyphonic synthesizers are hybrid designs that combine digital control with analog sound generation. In modular systems, however, building a truly pure analog polyphony can be both challenging and deeply rewarding.
In this video, we created a fully analog polyphonic structure using the VAEMI modular system. We used sawtooth waveforms on all oscillators. With 3 OSI-OP modules, we achieved 3-voice polyphony. By using VAEMI Analog Sequencers, we provided dedicated voltage control for each oscillator, resulting in a completely analog polyphonic sequencer.
The signal path was processed through our prototype analog filter module, creating a classic subtractive synthesis architecture. The entire system was synchronized via clock signals from the Beatstep Pro. The final recording was passed through an RE-201, adding a classic tape delay and spring reverb atmosphere.
Sometimes, chasing sound takes you back in time.
This pure analog polyphonic structure we built with VAEMI blends the feeling of the past with the modular technology of today.
You'll know what we mean when you hear it."

TipTop Polyphonic Modular + ASM Hydrasynth : "Entangled State" by gattobus
video upload by gattobus
"This track came out of the blue while I was playing and experimenting with TipTop Audio Poly Modular System and my ASM Hydrasynth.
This patch sounds organic and deep, a perfect blend between analog and digital!
I loaded a custom wavetable on TTA Vortex 6 then I set up a classic signal path going through the poly filter (TTA Octopass) and the poly vca (TTA Octogain). Then I added some external modulations coming from Hydrasynth CV outs, which turned out to be the best keyboard controller for this incredible system!
Star of the show is TTA Resonator that adds a very organic and ethereal texture to the entire patch!
These are the modules in my system:
Vortex 6 Oscillator
ATX-1 VCO
Octopass Poly Filter
Octostages Poly Envelope x2

Frap Tools Magnolia, 8-voice analog thru-zero FM polyphonic synthesizer | Project update
video upload by Frap Tools
Click CC at the bottom of the player for subtitles.
"Magnolia will be an 8-voice analog through-zero FM synthesizer, which we built to create sounds from the modular world through a classic keyboard interface.
Waveshapers, wavefolders, and, most importantly, analog linear through-zero FM unlock every sound associated with the 'West Coast' synthesis world. But that's not all! Fat resonant filters and powerful analog oscillators allow more traditional subtractive synthesis sounds as well.
A vast and flexible modulation section encourages complex patches with the twist of a knob, but it is always easy to keep track of what's going on thanks to LEDs on every source and destination. An arpeggiator and a sequencer complement the machine.
We are announcing and showcasing two pre-production units. We aim to release the final version at the end of summer, and it will show some differences. It may have a more refined interface, it will feature digital effects, and some of the features currently under evaluation may disappear.
We've been working on it for the last year, and we're eager to show it to the world!"
Follow-up to this post where you'll find additonal pics.
Update: press release follows:
Frap Tools to take on high-end keyboard synthesizer market with ‘West Coast’ MAGNOLIA making its public debut at SUPERBOOTH25
MEDOLLA, ITALY: Frap Tools, hitherto known as a manufacturer of Eurorack modules and accessories alongside professional audio compressors in the 500-Series format, is proud to venture into the world of high-end keyboard synthesizers with its introduction of MAGNOLIA — announced as an 8-VOICE ANALOG THRU-ZERO FM SYNTHESIZER built to unlock every sound associated with ‘West Coast’ modular synthesis through a classic keyboard interface — anchored around showcasing two pre-production units at SUPERBOOTH25, May 8-10, FEZ-Berlin, Germany…
As an 8-VOICE ANALOG THRU-ZERO FM SYNTHESIZER, MAGNOLIA unlocks every sound associated with the so-called ‘West Coast’ modular synthesis world with waveshapers, wavefolders, and, most importantly, analog linear TZFM (Through-Zero Frequency Modulation) Indeed, its intentions are made clear from the outset by the on point wording worked tastefully into its (initial) top panel design. No need to necessarily remain there, though, for fat resonant filters and powerful analogue oscillators also allow for more traditional subtractive synthesis sounds. And although a deep and flexible modulation section encourages complex patches with the push of a button and twist of a knob, switching modulations on and off with the TOGGLE function, it is always easy to keep track of what is going on thanks to the inclusion of LEDs (Light-Emitting Diodes) on every source and destination.
Digging deeper, MAGNOLIA features eight analogue voices with two oscillators — carrier and modulator — and 24 dB/oct resonant HIGH-PASS and LOW-PASS filters; the carrier oscillator has a through-zero core for precise, sideband-rich analogue FM (Frequency Modulation) sounds, so crystal-like pads to growling basses are available to all with the greatest of ease, while FM can be applied to the filters. Furthermore, sculpting sounds that have not been heard before on analogue polysynths are now perfectly possible, thanks to MAGNOLIA’s unique signal flow — think continuously variable waveform shapes and a wavefolder circuit per voice!
Those two oscillators are derived from Frap Tools’ BRENSO (https://frap.tools/products/brenso/), a Euroack module readily representing its creator’s primary analogue source of articulated waveforms whose degree of entanglement can be precisely set by the musician. MAGNOLIA’s Oscillator 1 is the ‘West Coast’ one with TZFM, wavefolder, and FLIP SYNC, while Oscillator 2 is the ‘East Coast’ one, with PWM (Pulse Width Modulation) and fine-tune. Whether wanting experimental FM sounds or punchy synth brass, they are always at anyone’s service. Speaking of Frap Tools’ unique modular soul, MAGNOLIA’s filter section is derived from CUNSA (https://frap.tools/products/cunsa/) — itself a quadruple analogue ping-able multimode resonant filter, saturator, mixer, and oscillator, no less!
Musically, MAGNOLIA sports a keyboard from fellow Italians FATAR, with polyphonic aftertouch capabilities for enhanced expressiveness, while a per-part ARPEGGIATOR and per-part 16-step SEQ (sequencer) serve to creatively complement the synthesizer still further. Features briefly worth drawing attention to here by way of ending on some more high notes include MAGNOLIA’s bi-timbral programs (with SINGLE, MORPH, DUAL, and SPLIT MODES); all-analogue signal path; three loop-able DAHDSR (DELAY, ATTACK, HOLD, DECAY, SUSTAIN, and RELEASE) envelopes; three digital LFOs (Low Frequency Oscillators); and 512 preset memory slots.
Anyone attending SUPERBOOTH25, May 8-10, FEZ-Berlin, Germany can get up close and personal with two MAGNOLIA pre-production units by swinging by Booth B049 there. Their creators will be showcasing them personally, eager to show the results of their hard work, while providing a passionate warm welcome. Frap Tools aim to release MAGNOLIA as a production product by the end of summer, albeit with some differences evident by then. The interface will likely be more refined, featuring digital effects, while some features currently under evaluation could conceivably be removed."

At its heart lies a Curtis CEM3394 voice chip—the same chip found in the legendary Oberheim Xpander—delivering warm, punchy, and expressive tones. Originally launched in the late '80s, the EWI3020M was part of Akai’s bold foray into wind synthesis, but its standalone capabilities and exceptional tone make it a sleeper hit for analog synth enthusiasts and modular-minded players alike.
Key Features:
Monophonic analog signal path with dual VCOs, VCF, VCA, LFO, and dual EGs
CEM3394 voice chip for rich, vintage sound
Wide modulation matrix: 7 sources, 10 destinations
50 patch slots (factory + user)
Waveforms include Triangle, Saw, Square, and Sync modes
Full MIDI In/Out for use with keyboards, sequencers, or DAWs
Rackmount format – a studio-friendly synth module with stage potential
Whether you're breathing life into it with a wind controller or sequencing it via MIDI, the EWI3020M is a versatile, expressive, and highly underrated gem in the analog world."
