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
Octogain VCA
Octopus USB/MIDI interface
Octo I/O
Octovert
Resonator

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."

West Coast Synthesis
video upload by 4ms Company
Patch notes via the 4ms MetaModule forum:
External Audio Path:
-Audio main output on ch. 1 and ch. 2
Internal Audio Path:
-Two VCOs are entangled with their audio outputs mapped to one another’s FM inputs.
-Each oscillator then goes into its own wavefolder.
-The wavefolder’s both have a dedicated lowpass gate.
-The low pass gates are fed into a VCA for volume modulation
-Each VCA is then sent into a stereo mixer
-The stereo mix feeds into two spring reverb units for Left and Right.
-A limiter is placed on the output for master volume control and clip protection
Internal CV Path:
-Free running random voltage generators are fed into a dedicated CV mixer for each VCO.
-The random voltage amount and crossmodulation are mixed with another to create a 1v/octave signal for the VCOs.
-The trigger outputs of each random voltage generator ping the lowpass gates.
-The random voltages go into a full wave rectifier and are used as CV signals for the two VCAs: this creates random volume fluctuations for each channel.
Metamodule knob mappings:
A - VCO 1 Frequency
B - VCO 2 Frequency
C - VCO 1 Random CV
D - VCO 2 Random CV
E - Random rate 1
F - Random rate 2
U - Random 1 crossmodulation
V - Random 2 crossmodulation
W - VCO crossmodulation
X - Wavefold
Y - Decay time
Z - Random shape

A use for aliasing that you may never have seen before!
video upload by Frap Tools
"Aliasing is usually a big no-no: it means that there's something wrong with your digital sound and with a guy named Nyquist. However, thanks to our Bagài, it is possible to make this bad thing a good one and have some fascinating timbre – with an all-analog signal path (for what it's worth)."

Background Modulars No.10 Buchla200 & DX5
video upload by Memetune Studio
"Don’t have a real Buchla 200 (cloned) and Yamaha DX5 to hand? No worries! Just put this video on in the background (in full-screen mode), and have the next best thing 😁
Here is 10 minutes of self-playing modular synthesiser randomness. Why not put it on loop - then you can have it bubbling away in the background while you do other things
A note on the patch: The DX5 is being triggered and pitched from the Buchla 200 modules (mostly a 280 in cycle mode and 262 Source of Uncertainty, plus some MARF) using a Kenton CV to MIDI Converter. The DX5 is programmed to make a percussive drum-like sound using six operators. The DX5 audio signal then goes back into Buchla modules - mainly the 277 and 288 Delays, which are being fed back on themselves to create the bowed-string-like sounds. The Dodeca module provides mixing, random panning and reverb. The SOU sends random voltages to the 280 so it cycles irregularly. The whole patch has a cybersynthetic nature because it is always on the edge of going chaotic with the feedback to the delays, but it keeps itself under control by injecting new DX5 sounds into the path just in time to settle it back down before it happens again"

Introducing Samarkanda 1953 Resampling Delay Performance Station by Xaoc Devices
video upload by Xaoc Devices




"Meet the lovely Samarkanda - a monster of a delay with unlimited potential
Xaoc Devices Samarkanda is a digital quad delay module with extensive patching capabilities and a lot of flexibility for signal mangling. It can be used as four entirely independent delays, a dual stereo delay, a complex/multi-tap or multi-channel delay, a quad/polyphonic resonator, a dual chorus, a dual flanger reverb, a looper (with sound on sound!), and a granulator, or any combination of those. You can reverse the delayed signal, hold it, squeeze and stretch it beyond all recognition and still go back to the original piece of audio captured in the buffer! The internal lossless normalization (the signal doesn't leave the digital domain) combined with top-notch components (including 24-bit AKM converters and 32-bit internal processing) are responsible for high sound quality. Samarkanda has been conceived in the truly modular spirit. Not only can you control almost all its features remotely with CV/gates, but the external feedback path gives you the opportunity to process the delayed signal with other modules.
Samarkanda offers a wide range of delay times beginning at a mere 0.5ms and reaching up to 15 seconds per channel. That means that, by stacking its four channels, you can achieve up to one minute delay! There are two operating modes switchable individually for each channel. Analog delivers pitch changes that resemble classic analog tape and BBD delays. When you combine it with the looping Hold function, you can play Samarkanda with any 1v/octave CV source - using the Sync function you can even loop single wave cycles. The Digital mode gives you a granular buffer-scrubbing effect (no pitch change) across the whole delay time range. You can seamlessly switch back and forth between modes without losing any information. You can use Samarkanda for multiple tasks at the same time - from four independent delay lines through any combination of channels processing the same signal up to a quad behemoth. You can also use the linking feature for ease of operation (the first channel in the chain acts as the main control source for the others).
As most settings operate on a per-channel basis, you can freely combine different features (such as analog/digital behaviour, delay time range, reverse and hold functions, etc.) in a configuration of your choosing. You can synchronize each of its channels separately to a different source, either via the Sync input, or by using the tap-tempo functionality (with multiplication and division galore). Should you ever get lost, the Purge button comes in handy when/if things start to spiral out of control!
Notable features:
Quadruple resampling delay
Lossless chaining of sections
Delay range of 0.5ms to 15 seconds per channel for a total of 60 seconds when stacked
Analog (tape-like) and digital (granular) sweep behaviours
Continuous, synced, and tap-tempo operation
Clock division and multiplication from 1:8 to 8:1
Buffer freezing and 1V/oct loop playback control
Reverse delay effect
Multiple options for coupling channels
width 42HP
depth 40mm (including cable bracket)
+230mA/-90mA

"Come and meet PATH the new DivKid & Vostok Instruments analog morphing router that is OUT NOW as assembled modules and DIY kits. Path builds on the interpolating scanner technology of Trace and performs the opposite function, rather than Trace doing 4 input scanning to 1 output, Path takes 1 input and morphs it across 4 outputs. Like a quad panner, open for creative audio and CV routing."
*TIMING INDEX // CHAPTERS*
00:00 Hello & previews
01:37 What is Path? Feature run down
03:08 Advanced FX sends with trails
06:19 Powerful modulation (+Trace combo!)
11:42 Unique panning FX (alternative to a quadrophonic panner)
14:39 Distributing triggers for filter ping riffs!"
Check with dealers on the right for availability.
"Path is a four-channel Interpolating Router created in collaboration between Vostok Instruments & DivKid.
Born from the roots of our previous module, Trace, Path picks its central concept and does something relatively simple yet powerful: it flips it.
The circuit routes one signal to four possible outputs, fading from one to the next following a soft slope response to ensure smooth transitions.
Path counts with Trace’s best features. It shares the same DC-coupled interpolating circuit at its heart, making it perfect for experimenting with any signal on any of its inputs.
Thanks to the fixed voltage normalled at its main input, Path is also a versatile and unique modulation source out of the box.
Its compact size and layout make Path a very performative and handy tool for adding an organic layer of movement and experimentation to every patch."

Sequence Replicatin' with MultiMod (Level 0) | Make Noise
video upload by MAKEN0ISE
"How would you go about replicating a sequence? When it comes to the modular signal path there are a number of intersection points to cut into. For example you could use the word “sequence” to refer to the final audio output of a synthesizer that is being sequenced. It could also mean the oscillator outputs prior to having filtering or effects applied. It could mean the series of stepped control voltage values that determine the oscillators’ pitches from moment to moment. That’s a beauty of the availability of signal flow to us in the modular synth, that we can cut in and disrupt at any of these points, all of which work together in concert to determine the ultimate output."

Meet the New GS Music Bree6 with Ernesto Romeo
video upload by GS Music
"Our website https://www.gsmusic.com/
Join us in this video as the legendary Ernesto Romeo takes the Bree6 Synthesizer for a spin for the very first time. Known for his profound expertise in electronic music and synthesis, Ernesto explores the depths of GS Music's latest creation, the Bree6, a marvel of analog synthesis technology designed for both studio and live performance.
Follow Ernesto Romeo ig: https://www.instagram.com/ernestorome..."
Press release follows:
After extensive research and dedicated efforts from our team, GS Music is proud to unveil the Bree6, our latest breakthrough in synthesizer technology. The Bree6 is a straightforward synthesizer offering six voices of polyphony, each equipped with a single voltage-controlled oscillator (VCO) and a sub oscillator. It has been meticulously developed to meet the needs of both studio and performance environments. The Bree6 features a fully analog signal path that includes a 4-pole low-pass voltage-controlled ladder filter (VCF), and a voltage-controlled amplifier (VCA). The control signals are digitally generated, incorporating one low-frequency oscillator (LFO) and two ADSR- type envelope generators. Additionally, the Bree6 integrates an effects processor with chorus and delay.
Designed for straightforward operation, the Bree6 provides intuitive access to its full capabilities without complex menus, making it accessible to both seasoned professionals and those new to synthesis.
No Menu Diving
The Bree6 interface is engineered for straightforward and intuitive use, ensuring easy access to its robust features, including MIDI connections, USB, balanced stereo audio outputs, headphone output.
Signal Path
The signal path in the Bree6 is entirely analog, comprising a single VCO per voice, a sub oscillator, a mixer, a 4-pole low-pass ladder VCF, and a VCA. The control voltages are digitally generated, featuring one LFO and two ADSR-type envelope generators. It also features a stereo digital effects processor with delay and chorus.
Oscillators
The Bree6 features a single VCO plus a sub oscillator per voice. The oscillator includes sawtooth and pulse waveforms, with pulse width modulation control that can be
modulated by the LFO. The oscillator tuning can be adjusted, and modulation can be applied from the LFO. The sub oscillator generates a square wave one octave below the main oscillator.
Filter
The Bree6’s filter is a 4-pole ladder-type low-pass filter with resonance control. It can be modulated by EG1, with velocity affecting the modulation depth, and can also be modulated by the LFO. It can also be controlled by the modulation wheel and aftertouch.
Chorus and Delay
The synthesizer offers a stereo ensemble type chorus effect. It simulates a string or vocal ensemble using multiple delay lines modulated by their dedicated LFOs.
The stereo delay can reach a maximum delay time of up to 1 second.
LFO
The Bree6 contains one LFO with selectable waveforms (triangle, ramp up, ramp down, square, and random with sample and hold). The LFO’s frequency can be set from 0.1Hz
to 100Hz, and modulation can be applied to the VCO, VCF, and VCA.
Envelope Generators
There are two ADSR-type envelope generators in the Bree6, designed for precise control over the dynamics of both the filter and the amplifier.

"Born out of collaboration between PWM and the late Chris Huggett, Mantis draws from the legacy of synthesizers like the Wasp and OSCar, but with modern refinements and performance. Blending sounds and techniques built over the years designing instruments for the likes of EDP and Novation, Huggett's final designs went into Mantis, and through some touch-up work and adding powerful MIDI capabilities, PWM brought Mantis to market to honor Huggett's legacy.
As a duophonic instrument, Mantis contains two independent voices—beginning with digital oscillators that are then processed through an entirely analog signal path, alongside a digital effects section. Mantis features mathematically-generated oscillators, running on their own DSP chip for maximum performance and quality. There are two oscillators per voice, plus a sub-oscillator, meaning that you can dial in a blended variety of tones as you see fit.
Possibly the star of the show on Mantis is the unique VCF design, utilizing a unique configuration devised by Huggett. Based on SSI2164 VCA chips, the multi-mode filters in each voice may be controlled simultaneously in series or parallel configurations, with a width control similar to what was found on the OSCar. This leads to a distinctive array of sonic potential, helping Mantis stand out from the pack.
Like other PWM synthesizers, Mantis features incredible digital control capabilities, including MIDI CC control over all parameters. Mantis is a modern synthesizer for the modern day, and a fitting tribute to the legacy of Chris Huggett's work."
