Plexiphon Is Now Shipping! | Make Noise

video upload by MAKEN0ISE

"On Saturday, October 3rd, at 3 pm, Tom Erbe will be at Perfect Circuit in Burbank, California, talking about all things Plexiphon and soundhack. The event is free!

The Make Noise Soundhack Plexiphon is a stereo, modeless spatial texturizer which allows for continuously morphing between reverberations and multi-tap echoes, the widest range of possible results being neither reverb nor echo, and all results highlighting and amplifying character previously hidden in the source material being processed.

The Plexus control simultaneously modulates the number of feedback paths in the algorithm, and their entanglement together. The Size of the paths determines the temporal relation between them, operating like a 'delay time,' or a 'room size,' at either extreme of Plexus.

Diffuse and Color offer softening/sharpening/darkening/brightening effects over time.

Couple and Skew are stereo operations: Couple determines to what degree the left and right sides are isolated or intermingled (from 'dual mono' to fully interlaced stereo), while Skew offers simultaneous inverse or tandem control of the left and right paths on the Plexus, Size, and Color parameters.

The Send gate input (normalled high, or patchable) determines whether and when the input signal will be fed into the Plexus.

An envelope follower is provided at the CV output for re-integration of the Plexus into its own controls or elsewhere in the voltage controlled system.

Plexiphon is built from entirely new code by Tom Erbe, specifically for Make Noise’s newest digital hardware.

Introducing Haas Zone Processor

video upload by Verbos Electronics GmbH

"Introducing Haas Zone Processor. In stores now.

Video by: ‪@coquinati_music‬

In 1951 Helmut Haas wrote the paper On the Influence of a Single Echo on the Intelligibility of Speech, describing the psychoacoustic effects of delay on sounds. Since the paper describes short delays, “The Haas Effect” generally refers to delays shorter than 50mS. The Haas Zone Processor enables the effects in this range, including chorus, flange, phase cancellation, doubling, ADT, waveshaping and others.

At the core is a multi-tapped digital Delay Bank largely influenced by vintage studio processors including the Marshall Time Modulator. Tap1 can be switched and swept from less than 1mS up to 20mS. Tap2 is chained from the output of Tap1, adding an additional 1mS-20mS. Tap3 ranges from 9-42mS. In addition to having their own full volume outputs, all 3 delay taps can be blended with the Dry input signal in a voltage controlled mixer.

Also included is a Bandpass filter built from a 2 pole hipass followed by a 2 pole lowpass. Bandwidth can be swept from very narrow all the way to full bandwidth. Frequency can be swept across the full audio range and voltage controlled through a bipolar attenuator.

To the left is a Voltage Controlled Oscillator, similar to the modulation side of a Complex Oscillator. Included is a Triangle, Square and Sawtooth wave that range from 0-10v. The Frequency can sweep from more than 1 minute per cycle all the way up to audio range and tracks volt/octave.
There is an envelope Follower on the input and both it and the triangle output from the Oscillator are normalled to the c.v. inputs on the Delay Time. The output of Tap3 is normalled to the input of the Bandpass filter and the output of the Bandpass filter is normalled to the Feedback In. Through tweaking the Delay Time, Oscillator Frequency and Bandpass Frequency multiple resonance points can be accentuated. The Haas Zone Processor is intended to be used as an effect, inside a patch as waveshaper or as a voice on its own."

This Eurorack filter has AUTO DYNAMICS! // Flow 3 from Joranalogue *MEGA DEMO*

video upload by DivKid and Joranalogue Audio Design

"As we'd expect from Joranalogue, they take inspiration from classic, seemingly simple functions and turn them into musical and technically impressive devices. Flow 3 is a compact filter that builds upon on the idea of an auto wah, it's a filter with 'auto dynamics'. There's on board modulation, that can modulate itself or your modular system, stave variable filter outputs, CV over everything and an easy to play with layout in 6HP."

Update: Press release follows:

Joranalogue Audio Design announces availability of Flow 3 auto-dynamic filter module for Eurorack that sounds bigger than it looks

STEKENE, BELGIUM: having made its impressive-sounding debut during a showcase at SUPERBOOTH26, May 7-9, FEZ-Berlin, Germany, high-quality Eurorack music synthesiser modules-maker Joranalogue Audio Design is proud to announce availability of Flow 3 — an auto-dynamic filter that sounds bigger than it looks, thanks to the novel variation on the classic state variable filter topology that lies behind its compact 6 HP panel — as of August 25…

Firstly, Flow 3’s core integrator saturation of its simultaneous — low-pass (LP2), attenuates frequencies above the filter frequency (or cutoff) at -12 dB/octave and self-oscillates at a phase of 180°; bandpass (BP2), selects a band of frequencies around the filter frequency (but below and above that the attenuation slope is -6 dB) and self-oscillates at a phase of 90°; and high-pass (HP2), attenuates frequencies below the filter frequency at -12 dB/octave and self-oscillates at a phase of 0° — outputs provide for a sound that is clean yet distinctive.

RESONANCE response is exceptionally smooth — it, too, can easily reach self-oscillation (at higher feedback levels), the temperature compensation and exact calibration effectively transforming Flow 3 into a reliable quadrature sine/cosine VCO (Voltage-Controlled Oscillator) with tight pitch tracking.

The ace up Flow 3’s sleeve, however, lies in its auto-dynamic nature — helpfully highlighted by the non-erasable AUTO DYNAMIC FILTER graphic positioned across that compact, clean-cut 6 HP panel. After all, it is a filter that can modulate itself, achieved by a combined DECAY generator/envelope follower circuit controlling the filter frequency over an adjustable range; either fire decay envelopes from external triggers, or flip it to AUTO mode to follow along with the incoming signal’s amplitude envelope (or both, simultaneously).

Saying all that, then, creating heavy-hitting analogue kick drum sounds becomes a breeze, but, with a bit of patching, Flow 3 can even be used as a spectrum splitter (or crossover), cleanly separating the full audio range into low and high portions, for dual-band signal processing — perfectly possible thanks to the Linkwitz-Riley filter response at minimum resonance.

Ultimately, users of Flow 3 can clearly get carried away as the Eurorack module concerned creatively takes the old auto-filter concept to new voltage-controlled heights, hearing for themselves exactly what the fuss was all about at that impressive-sounding SUPERBOOTH26 showcase!

Coming complete with a 16-to-10-pin Eurorack power cable, two black M3 x 6 mm hex screws, two black nylon washers, and a hex key, Flow 3 is available as a 6 HP module — measuring 128.5 mm (H) x 30 mm (W) x 52 mm (D) with a +12 V: 45 mA/-12 V: 45 mA maximum current draw, reverse polarity (MOSFET) power protection, 100 kΩ impedance inputs and 0 Ω (compensated) impedance outputs — through Joranalogue Audio Design’s growing global network of authorised dealers at a MSRP (Manufacturer’s Suggested Retail Price) of €215.00 EUR or $225.00 USD.

Superbooth 26 - Xaoc Devices Introduces Skopje & Budapeszt

Superbooth 26 - Xaoc Devices Skopje & Budapeszt

Xaoc Devices proudly debuts two new products at Superbooth 26: Skopje 1988 Dual Quantizer and Budapeszt 1972 Exploratory Stereophonic Spectral Lattice Network. Here is some information on the modules.

On the surface, Skopje is a seemingly simple compact (6HP) dual quantizer with two independent channels. However, some clever features coupled with high-precision A/D and D/A converters make it a complex (though extremely easy to use) compositional tool suitable for all kinds of musical outcomes. The user interface is similar to Zadar with frontpanel labels clearly indicating the features available for adjustment. No menu diving as the small OLED display is only used for selecting banks and scales. Each channel is able to quantize its input to a different scale from a different bank (up to 100 banks each containing up to a 100 scales - if you're deranged enough to need as many... ;-). Skopje stores its data on a regular microSD card. The module supports its own very simple scale format (a straghtforward TXT file you prepare on your computer), as well as any of the abundant SCALA files you throw at it. You can mix and match different scale format files in one bank. Various tuning systems and description formats supported. Microtonality galore! Our own scale programming system additionaly includes a few clever features, e.g., various voltage limiting settings. But there's more.

Got a lovely sounding VCO, but with volt/octave tracking leaving something to be desired? Skopje to the rescue - you can quickly calibrate any of its channels to fit your VCO like a glove for precise tracking! Other notable features include: glide, scale switching via triggers or CV (great as a performance/compositional tool with your own scales/note combinations), and transposition (including unquantized for vibrato).

Skopje is in production and will be available in June 2026.

PS Yes, this is a game of life screen saver on Skopje in one of the photos :-)

MAIN FEATURES:
- dual quantizer with precision A/D & D/A converters
- highly customizable
- compatible with microtonal scales
- OLED display for ease of use
- up to 100 banks, each with up to 100 scales
- VCO calibration feature
- data stored on microSD card
- SCALA file support
- 6HP

BUDAPESZT — 1972 Exploratory Stereophonic Spectral Lattice Network

Budapeszt is a stereo dual spectral processor built around the interference of resonant structures. It features two independently tunable comb-type filters with six distinct modes. Each filter has its own set of controls, with two separate triangle LFO's providing internal modulation (with free and synced operation, and an envelope follower mode on top). The real magic happens in the interference between two stereo filters though. The overlap of two resonant structures weaves a spectral lattice: a complex grid of peaks and voids. The final geometry of that lattice is determined by the relationship between the channels rather than by either one in isolation. To encourage experimentation and for even more sonic flexibility, multiple feedback paths are available, including cross-coupled feedback between the filters. There's also a feedback phase inversion switch for each filter.

Filter modes include delay-based, phase-based, and filterbank-based approaches to shaping the frequency domain. The first mode draws on a signal model inherited from Xaoc Devices Samarkanda, enabling artifact-free pitch behavior across the full frequency range. The remaining modes distribute resonant energy in ways ranging from the mathematically orderly to the perversely irregular. That being said, more familiar results, like flanging and chorus, are also easily attainable - delivered by Budapeszt with unusual precision.

Budapeszt is equally at ease processing oscillator waveforms and complex samples. It eagerly responds to short triggers with percussive transients whose character depends entirely on what the two channels are doing to each other. The interaction between the two channels is the instrument. Two channels agree, and the result is color. Two channels disagree, and the result is stormy weather. The space between agreement and disagreement is where Budapeszt lives.

It's a noise gate, it's a noise suppressor, it's a compressor, it's an expander, it's stereo.

The Specs and Stats:

Width: 6hp
- Attack and Release knob for envelope(s)

- Threshold for suppression/compression (0V - ~8V)

- Floor controls the amount of suppression/compression from -100dB to Unity and even up to +10dB for expanding the louds louder or make the quiets a bit louder.

- Level controls your overall output level

- Gate/Comp switch: When in "Gate" mode, whenever the input falls BELOW the threshold level, the envelope will engage towards the floor setting. When in "Comp" mode, the envelope will trigger when the input rises ABOVE the threshold setting.

-Stereo inputs and outputs. The envelope follower is assigned to the Left input, so the L input can also be used as a sidechain input for a mono signal (into In-R).

- Engage input. This is a gate input for manually engaging the envelope.

- Threshold CV input. This offsets from your knob position.

- Floor CV input. This also offsets from your knob position.

- Duck CV Input. This is an envelope follower input that applies and inverted envelope to the level of the signal. Send a simple pulse or trigger, an actual kick, an envelope, or anything else into this to duck your signal.

-Envelope Output. The envelope Output does not follow the "floor" settings and always outputs a full voltage envelope.

Special thanks to SetonixSynth and many others for really helping make this module a reality.

Crazy Chicken Modular SHRIMPY filter musical demonstration

video upload by Fedir Tkachov Music

"Musical exploration of new eurorack filter by Crazy Chicken Modular - SHRIMPY."

Shrimpy is a fully analog multimode voltage-controlled filter with three simultaneous audio outputs: low-pass, band-pass, and high-pass. It was designed with a strong focus on character rather than neutrality.

The resonance is voiced to emphasize midrange frequencies, giving the filter a present, expressive tone that cuts through a mix. At higher settings, it becomes vivid and assertive without collapsing into thinness.

At the heart of Shrimpy lies an unusual distortion chain integrated directly into the filter core. This distortion adds a pleasant crunch, enriching the sound. When pushed further, it can turn glitchy and rustling, introducing rough textures and unstable edges that make the filter feel alive. It should be noted that the distortion sound characteristics will depend on the Shrimpy settings and the input signal, since distortion occurs in the filter core itself, rather than at its input or output.

All parameters are fully voltage-controllable:
Cutoff frequency (with and without attenuator)
Resonance
Distortion amount

This makes Shrimpy a flexible yet opinionated sound processing tool, well suited for experimental patches, aggressive basses, textured leads, drones, and evolving soundscapes."

Soft Memo is a hybrid stereo multi effects desktop unit with eight digital CV controlled FX programs, two analogue feedback paths and two complex voltage-controlled LFOs.

It has patch points to integrate external synthesisers and sequencers and it is designed to creatively reshape your sounds with a menu-free hands-on approach.

You can create patches by connecting inputs and outputs with eurorack-standard 1/8" jacks.

All its inputs are protected from potentially dangerous voltages.

It generates (and reacts to) control voltages in the 0-5V range: when a CV signal is patched into an input, its knob becomes an attenuator for the incoming signal.

The patch points are visually divided between inputs and outputs: the inputs are placed in the middle of a white circle while the outputs are not.

Soft Memo is powered by a 9V center-negative (500 mA) power supply, the standard PSU used with most guitar pedals.

Features:

Eight FX programs

A total of 25 patch points

Two high gain preamps

Two feedback paths made of analog VCAs and resonant analog VCFs


Two complex voltage controlled LFOs with clock division and phase offset control

An envelope follower

A→B buttons to set how the two channels controls interact with each other"

Café Quantum

video upload by Patch Point

"By Ciat-Lonbarde"



"When the Cocoquantus2 first appeared, it didn’t just find an audience—it created one. Musicians, experimentalists, producers, and curious tinkerers fell in love with its organic chaos, character, and uncanny ability to turn accidents into art. It became a modern cult instrument because you couldn’t play it without forming a relationship with it.

Café Quantum continues that lineage with reverence—then boldly invents a new chapter.

At its core, Café Quantum preserves the tactile immediacy and playful unpredictability of the Coco ecosystem. But surrounding that familiar heart are entirely new tools designed to make the instrument feel more alive, more intelligent, and more expressive.

One of the biggest leaps is the open-source programmable engine. For the first time, players can write their own behaviors—little sonic personalities— at the Cafe modules, one for each side, and the Quantum module can carry them out by patching points. Whether it’s generative patches, evolving modulation, rhythmic structures, or strange autonomous rituals, the instrument becomes a creative partner. And thanks to the dedicated banana sockets, these behaviors integrate directly into the patch ecosystem. The Cafe module becomes a blank page for your imagination, shaped as far as your coding skills can carry you

The preamp has grown up too. Now it features a Norton gain character and adds a VCA input, making external dynamics, sidechaining, and voltage-controlled level manipulation feel effortless. On top of the newly redesigned preamp features you still have the envelope follower that opens the door to all sorts of expressive interactions between incoming audio and internal modulation.

Then comes the new magic trick:
A radio-based gestural controller sits atop the entire system, allowing 4 hands-free modulation reminiscent of a theremin. Move in space, and the instrument responds—pitch, delay time, grain density, feedback paths, whatever you choose. It transforms performance from knob-twisting to full-body expression."

Rack Mount Sennheiser VSM-201 Vocoder

Starting Bid $5,000

Estimate $20,000 - $40,000 USD

A late 1970s Sennheiser VSM 201 Vocoder with no serial number from the personal studio and collection of Florian Schneider of Kraftwerk (see images). While it’s said that only a few dozen of these Vocoders were produced, a few examples made it into the hands of forward-thinking musical artists including Herbie Hancock, Daft Punk, and of course, Kraftwerk, who used a VSM-201 like this on their albums Man Machine (1978) and Computerworld (1981). The VSM-201 has an intelligible sound that has not yet been bested by modern gear. Includes power cable. This VSM-201 has been removed from its wooden enclosure (which bears the serial number plate) and modified with a metal rack mount casing, presumably for live use. Requires 240v, IEC power cable not included.

Dimensions: 19 x 9 x 9 inches

Where Modulation Connects

FAC Polyflo is an AUv3 plugin for modulating and sequencing MIDI instruments and modular gear via control voltage. It outputs MIDI and analog CV simultaneously, making it well-suited for hybrid setups that combine digital and analog equipment.

The plugin includes two LFO generators offering 10 waveforms, including classic shapes and random spline, with support for cross-modulation and syncing. It also features an envelope follower that tracks audio FX input or an external sidechain. The generated signals, together with the host clock and MIDI input, are fed into six independent FLO(W) processors.

These processors combine, shape, and route inputs using math operations, conditional logic, and comparators. Each FLO includes individual polarity, division, and multiplication controls, providing deep and flexible modulation that balances chaotic creativity with precise timing.

Each FLO processor output is connected to its own output bus, enabling easy integration with hardware via DC-coupled audio interfaces like the Expert Sleepers ES-9. For simpler setups, FLO outputs can be routed to the stereo output. FAC Polyflo can also convert MIDI notes, pitch, and control changes into control voltages, making it a powerful MIDI-to-CV solution.

If you prefer to work exclusively with software, the plugin runs smoothly in software-only environments with full MIDI support, making it equally suited for purely digital workflows.

FAC Polyflo works as both an Audio Unit FX and MIDI FX, featuring a clean, touch-optimized interface with precise control and waveform visualization. It’s available as an AUv3 for iOS (iPad/iPhone), macOS, and Vision Pro, and requires a compatible AUv3 host app to run.
