Doepfer A-188-9 High Speed VCO - Audio Demo

video upload by Doepfer Musikelektronik GmbH

"Over the last month, we have been recording videos for our Instagram channel. Here is a compilation of some of the clips!

In the video, the A-121-S stereo filter is mainly used as an end-of-chain filter. In combination with the A-149-4 quad random voltage source, it is possible to add modulation to the stereo field.

The feedback path was often patched in the clips, for example with a bandpass filter that had high resonance. This can lead to some pretty crazy sounds, as you can hear!

Another interesting thing to try is playing really high or low notes. Some of these the BBD is unable to track, which results in some quite nice glitches.

The A-188-9 and A-188-1 BBD combo offers a wide range of sound possibilities and often produces happy accidents. It's totally worth trying!

Questions? Let us know!

Module A-188-9 is a so-called high speed VCO that tracks prefectly to the 1V/oct scale in the frequency range of about 15kHz ... 500 kHz. The main application is the exact drive of BBD modules (A-188-1/2) to generate sounds realized by means of the so-called Karplus-Strong synthesis. But even in cooperation with other modules featuring high speed inputs (e.g. digital noise, delay, frequency divider) the A-188-9 makes sense. In principle, the module is made of a precision audio VCO followed by a PLL (phase locked loop) unit that multiplies the frequency of the audio VCO by 32. Thus the module can be used also as an audio VCO as it features the standard waveforms sawtooth, triangle and rectangle with adjustable pulse width."

"Rossum Electro-Music works its' way into the 5U system. The results are pretty nice.

Using a Trident Oscillator with quantized pitch CV from a Mob Of Emus into three envelopes from Synthetic Sound Labs Octal VCA Expander, then on to the Rossum Panharmonium Mutating Spectral Resynthesizer.
A tap off the Trident is sent to the Rossum Linnaeus filter for a percussive FM part which starts the work. The timing is from the Moon Modular 563 Trigger Sequencer.
The rhythm section is the Synthetic Sound Labs / Hagiwo Geo Gruvn euclidean sequencer for all the parts.
The bass part is the SSL Woven Spirits (MI Plaits) in wavetable mode.
The dual Q960 sequencers are transposing the 1V/Oct input to the Panharmonium and sending various control voltages to the bass and another pad swell sounds from the 5U system.
All recordings are in real time to Cubase 12 and video is edited in Final Cut Pro."

Multimode Tube Filter, Saturator & Beyond! // VAMP from Apollo View Modular

video upload by DivKid

"With Vamp Apollo View modular took the early Korg MS-20 and MS-10 filter designs, which favoured non-linear character over stability and control, they added more character with a tube input saturation stage and tube resonance feedback path, further output clipping stage options and then designed in modern stability and control. I joke in the video the filter is so rubbery it might as well be wearing a gimp mask. Vamp is also multimode with low pass, band pass and high pass modes with routable pre/post VCA and gain option, smart normalled CV options and prevision circuitry to turn it into a full single module tube voice, killer kick drum and more.

VAMP
8HP Multi-Mode LP/BP/HP Sallen-Key Filter with Tube Saturation & Distortion

VAMP is a multi-mode analogue filter that gives you low-pass, band-pass, and high-pass responses in a compact 8HP design. At its heart lies a classic Sallen-Key topology supercharged with real vacuum tube (12AU7) saturation and multiple stages of clipping, letting you move seamlessly from smooth, hi-fi filtering to snarling, overdriven character.

One half of the tube is used to saturate the input, while the other half provide MS-20-inspired resonance limiting (tube, not diodes). With FLOW placing the VCA pre-tube or post-filter, and FANGS selecting Off / Soft / Hard output clipping, VAMP ranges from subtle warmth to ferocious harmonic destruction.
FEATURES
Three filter modes: low-pass, band-pass, and high-pass
Classic Sallen-Key topology with tube saturation and clipping

Make Noise Introduces PoliMATHS and QXG

video upload by MAKEN0ISE

Check with dealers on the right for availability. User video by Cinematic Laboratory further below.

PoliMATHS [MSRP: $459] is an eight-channel CV and Audio event generator for the New Universal Synthesizer System or any Eurorack modular synthesizer. It uses a single set of controls to generate complex functions at eight independent channel outputs. PoliMATHS’ functions are made up of two components: first, the well-known Rise-Fall envelope with variable Curve (familiar from the original MATHS and Function and 0-Coast Slope); and second, a variable-Shape Oscillation whose amplitude is controlled over time by the Rise-Fall envelopes. This oscillation can be either low frequency for the creation of complex control functions, or audio frequency for native generation of audio events/notes with optional tuned pitch control via 1v/oct control voltage. PoliMATHS also includes output headers for creating pre-patched connections to the control inputs of QXG.

Activate channels in many possible patterns using Channel Index, Round, and Parallel Modes
Modulate parameters across channels with Spread or Modulation Dissemination
Designed to work with MultiMod and QXG and future NUSS modules
Chain to QXG for immediate eight channel amplitude control


The Quad Stereo Gate (QXG) [MSRP: $239] music synthesizer module is a Four Channel Stereo Low Pass Gate and Mixer. Like the DXG before it, the QXG utilizes a new low pass gate circuit that does not use vactrols. This circuit is 100% analog and its response was arrived at after many months tailoring it to meet or exceed the expectations that have been set by all the vactrol low pass gates that Make Noise has created over the years. Additionally the QXG adds a Vactrol button to select between a Slow, low-pass-gate-like response emulating the decay time of a vactrol (Vactrol button ON), and a Fast precision response that still maintains the gentle filtering characteristic (Vactrol button OFF). Fast response can be especially useful when patching QXG with complex and quickly-changing functions such as those generated by PoliMATHS with the OSC circuit in use. The QXG also includes a Stereo Sum Output with voltage controllable Stereo Spread to quickly route all four channels across the stereo field. Each channel also has an individual output that removes the channel from the Sum when patched. In addition, QXG includes signal and control input headers for creating pre-patched connections from the outputs of PoliMATHS and MultiMod.

PoliMaths & QXG | How does it sound when you know nothing?

video upload by Cinematic Laboratory

"Today MakeNoise has introduced PoliMaths and QXG. My dealer already had them in stock (!) and allowed me to buy them - under the strict condition to keep it a secret until after the official launch video. So I had the opportunity to make a video in one day, without access to any help from the manual or the MakeNoise launch video. Normally I'd do my homework first, but this opportunity is rare. Usually, I can intuitively figure out how a module works, but with PoliMaths, almost nothing is familiar, and what's familiar works differently. So I've probably been using a MonoMaths, but since I decided to get two, there's still a Poli vibe to it.

This is probably one of the worst videos I've made so far, but it's fun to patch in the blind with zero knowledge, and this was the only day I could record, edit and post it. So forgive me for being a MakeNoise groupie. I am biased, but I also think it's for a good reason. MakeNoise managed to make something extremely innovative. I'll make a proper video soon, and I'll figure out what to do with this one later."

CubuSynth Introduces ARKARION Eurorack Analog Synthesizer Voice

video upload by CubuSynth Modular

"The ARKARION is a complete analog synthesizer voice, housed in a Eurorack module, with digitally controlled signal routing. It combines the tactile experience of analog patching with the generative potential of randomized patches, all controlled via a single button or external gate signal.

Inspired by a fictional "DNA synthesis" concept, the ARKARION interprets a virtual genetic code to define routing schemes for CV and audio. This allows complex, evolving sound design with minimal patching.

This synthesizer is designed for users seeking a unique blend of structure and chaos, combining traditional subtractive synthesis elements with a digitally modulated signal flow. Whether played from a MIDI source, sequencer, or by hand, the ARKARION delivers a wide range of timbres, from tightly controlled tones to wild and unpredictable textures.

Weston Precision Audio: SV1 & SF1 | Full Demo and Review

video upload by Happy Mag

"Tasteful design and even tastier tone — that’s Weston Precision Audio! 🎛️
Met Devin at Buchla and Friends earlier this year and it was an absolute treat 🙌

Starting with the SV1: a dual stereo VCA with both vintage and clean paths — four VCAs in total 🔥
Vintage brings warm saturation with discrete transistors, while the clean side is modern, transparent, and tight 🎯
Run it in mono or stereo, link controls, bias your CV, and boost gain up to +6dB.
Need grit? Crank the input or flip the Overdrive switch for creamy distortion or sharp clipping 💥
And yes — zero-crossing detection eliminates clicks from fast envelopes. Smooth as 🧈

Next up: the SF1, a stereo or dual-mono VCF with two identical 4-pole filters.
Switch between LP, HP, BP — or tap into notch, all-pass, and phaser outputs too 🌈
Link the filters or keep them independent. Modulate everything, shape stereo motion, or use it as a sine oscillator with 1V/oct tracking 🎶
It’s a filter, it’s an oscillator, it’s a full-on sound design weapon 🧪

Head to WestonAudio.com to dive deeper.
And shoutout to Pig Hog for keeping the patch bay clean 🐗⚡️

IM TZ Dual VCO demos

video upload by Todd Barton

"This and other great modules are available at https://www.infinitemachinery.com/

Also, there will be a booth at Knobcon next month https://www.knobcon.com/"

"The TZ Dual VCO is two full featured VCOs on in a single 16HP module. Both VCOs output sine, square, saw, triangle and PWM wave forms. Each VCO also has thru-zero and expotential FM input. The type of FM is selectable using a toggle switch. An important feature of TZ Dual VCO is the FM input for each VCO can be control by a VCA input. A potentiometer adjusts the overall maximum of the FM input while the VCA provides an amplitude envelope.

Each VCO has the following inputs:

1V/Oct
PWM CV
FM signal
FM signal VCA
Each VCO has the following wave form outputs:

Sine
Square
Saw
Triangle
PWM
Each VCO has these adjustment knobs:

Coarse
Fine
PWM
FM amount
The upper VCO can be synced with the square wave of the lower VCO. A three position toggle switch is used to select hard sync (up), soft sync (down), or no sync (center).

Switchable Sync-Mode (from Rev.6)

The XR22 VCO FT is a VCO with amplitude modulation option – which can be used for volume control, or ring modulation of the oscillator’s sine/triangle output. The AM-input signal is added to a DC-voltage adjustable by knob ‘Gain’ (between ca. +/-5V) and the sum voltage is being internally multiplied with the sinewave/trianglewave The result is an oscillator amplitude depending on the ‘Gain’-DC plus AM-input signal. The applied AM-input signal can be mixed to the VCO output signal (modulated or unmodulated) too – a kind of ‘dry/wet’ control with the mix provided on the sine/triangle output. With no AM-input, the XR22 VCO FT behaves like a normal sinewave/triangle VCO, then its volume is controlled by knob ‘Gain’. Whereas with the knob ‘Gain’ in center position, the oscillator tone is becoming almost muted, and the input signal on ‘AM in’ controls the amplitude of the wave completely; thus the VCO can be used as a ring modulator.

The FSK (frequency shift keying) option provides two internally switchable different oscillator frequencies F1 and F2; each controllable by the two big-sized knobs (and their respective fine-tuning knobs and CV inputs). Switching between F1 and F2 can be done manually or by a logic signal (e.g. a gate signal) applied on input ‘FSK in‘. Further, it is possible to use the XR22 VCO FT‘s squarewave output for FSK switching. This will result in ramp or sawtooth (on the sine/triangle output) and pulse (on the squarewave output) waveforms. The falling and rising edges of the of the sine/triangle signal and the duty-cycle of the squarewave output are independently adjustable, and/or controllable via CVs of F1 and F2.

Furthermore, there is a switch for linking F1 to F2. In this case, the ratio between F1 and F2 is remaining the same, independently from the frequency, and ensuring properly 1V/oct. CV tracking.

A switch allowes to enable ‘sync mode’: An applied trigger will restart the wave always at the same point, useful for synced LFO applications and more.

For optical control, the XR22VCO FT has a full-color LED for AM visualization and a 2-color LED for FSK control.

Arcaico Murena Stereo filter, vca mixer #synthesizer #eurorack #modularsynth

video upload by Arcaico Instruments

"Arcaico Murena is a feature-rich analog module designed to deliver a distinctive, unpredictable, and versatile sound. With a width of 26 HP and a depth of 38 mm, the Murena is a concentration of functionality in a compact space.

A 6-channel mixer, each equipped with a distortion VCA, attenuverter and switches to select the internal routing destination. The channels are divided into two groups of 3, allowing flexible stereo management. Each VCA can be controlled either manually via the panel or via bipolarized CVs, offering extensive modulation possibilities.
Each group of 3 channels terminates in a multi-mode filter , capable of generating extremely aggressive sounds. After the filter, the signal can be routed to a distortion or directly to the mix. This configuration allows the two groups to be treated as a stereo pair or to use A-B crossfade modulation for dynamic transitions.
Every parameter of the Murena is manageable either from the panel or via CV, offering complete and creative control. The ability to patch the module to itself allows endless sonic combinations to be explored, making each use unique and unpredictable.

New Eurorack Modules Coming From Doepfer

Doepfer will be showcasing the above new modules at SUPERBOOTH25. Details on each follow.
Check with dealers on the right for upcoming availability.

Module A-119-2 is kind of a dual version of module A-119 without envelope follower. Instead two amplifiers are available and the module width is 4 HP only.

The module contains two amplifiers with separately adjustable amplification levels. Each channel is equipped with an overload display. The module can be used also for stereo signals, e.g. the stereo output of a smartphone.

Controls and displays:

Level 1/2: manual control of the amplification in the range 0 - about 45.

Overload 1/2: overload LED, begins to light up for output levels beyond about 10Vpp (+/-5V)

In 1: audio input 1 (monophonic or stereophonic, see technical details)

In 2: audio input 2 (monophonic)

Out 1/2: audio output (monophonic)

Technical details:

for higher amplifications the two amplifiers can be daisy-chained

normalling options: the signal applied to socket In 1 can be normalled to socket In 2 in different ways by means of a jumper on the pc board:

socket In 1 is connected via a mono patch cable (standard patch cable) to a monophonic signal and this signal is normalled to socket In 2 (i.e. the same input signal for both sub-units): jumper on pin header JP2 in upper position

socket In 1 is connected via a 3.5 mm stereo TRS cable to a stereophonic signal and the second channel of the stereo signal is normalled to socket In 2: jumper on pin header JP2 in lower position

no normalling: jumper is removed from pin header JP2

all inputs and outputs are DC coupled. Thus the module can be used also for the amplifications of control voltages.

The Infinite Machinery Hexa VCA is a 6 channel VCA with DC coupling and a unique normalization function. All in 12 HP

Signal inputs are DC coupled.
CV input response, 0 to +5V

Maximum amplification is unity gain, or 1.

Channels with no CV input will have CV normalized
to the CV of the channel above. This cascading of CV
values is defined in two groups, channels 1 - 3 and 4 - 6.

For example: If CV is patched to channel 1 and no CV
patched into channels 2 & 3 - Channels 2 & 3 will
follow the CV of channel 1.

Patch CV into channel 2 and nothing into channel 3
then channel 3 will follow the CV of channel 2.
The same hold true for channels 4 - 6, with 4 being
the start of the CV cascade.

Trilling Synth Modules Introduction

video upload by Dirk de Bruin

"I’ve designed a set of original Eurorack modules with intuitive interfaces and powerful features to help you create melodies, harmonies, and custom sequences in your synthesizer setup.

The T=3^x⋅2^y Midi Clock Divider makes it easy to explore rhythmic possibilities. The intuitive front panel shows the relationship between all outputs at a glance.

The 4051 Permutational Sequencer turns simple gate signals into complex sequences. This sequencer uses three gate inputs as a binary number, which determines the order of its steps.

Take your melodies and harmonies to the next level with the MC2VQ MIDI Controllable Dual Voice Quantizer.

https://www.kickstarter.com/projects/..."

Musically Meaningful Clock Divisions

The T=3^x⋅2^y Midi Clock Divider makes it easy to explore rhythmic possibilities. The intuitive front panel shows the relationship between all outputs at a glance.

Flexible Rhythms: Outputs are organized into triplet, standard, and dotted note divisions, perfect for creating musically meaningful patterns.

Seamless Integration: Combine any three outputs with the 4051 Permutational Sequencer for instant access to unique and inspiring sequences.

Reset in and out: To sync to other modules or use the reset in to make it reset itself if you want different sequence lengths.

Whether you're building complex grooves or experimenting with polyrhythms, this module simplifies the process.

Simple Inputs, Complex Sequences

The 4051 Permutational Sequencer turns simple gate signals into complex sequences. This sequencer uses three gate inputs as a binary number, which determines the order of its steps.

Dynamic Variations: Feed it three successively halved standard notes like quarter, eighth and sixteenth notes for a standard left-to-right sequence. But the real magic happens when you replace any of the inputs with another signal, resulting in limitless creative possibilities and rhythmic variation.

User-Friendly Design: Color-coded inputs make it easy to understand and control.

CV Output Range and Level Options:

The CV output range is adjustable via a dedicated switch, allowing you to tailor it to your specific needs. Additionally, the level knob provides precise control over attenuation for fine-tuning the signal.


Trigger Output:

Each time the sequencer advances to a new step, a trigger pulse is sent from the trigger output, making it easy to synchronize with other modules or external gear.

This sequencer is a powerful tool for creating evolving patterns that push your creativity to new heights.

Perfectly Spaced Notes, Dual Voice, MIDI Control

Take your melodies and harmonies to the next level with the MC2VQ MIDI Controllable Dual Voice Quantizer.

Dual CV/Gate Output: Creates two sets of CV/Gate outputs from the same scale or chord, resulting in lovely and complementary harmonies.

Unique Mixing Capabilities: Blend the three analog inputs differently for each output using dedicated mixers, generating beautiful harmonies or cascading arpeggios.

MIDI Input: Use a MIDI keyboard or sequencer to set scales or chords on the fly, enabling seamless chord progressions and harmonic shifts.

MIDI Output: Use the two voices generated by the quantizer to control your MIDI synths, or send the output to the next MC2VQ to synchronize scales across both modules.


Smooth Transitions: The quantizer’s algorithm distributes active notes evenly across the 1V/oct range for fluid and consistent transitions.

Trigger Inputs: Optional trigger inputs let you synchronize outputs with a fixed rhythm for precise timing.

Whether you're composing melodies or creating complex arpeggios, this module provides a unique and expressive way to shape your sound.
