Modular for the Masses
Nyquist Nightmare
Audio Mangling Modulator/Demodulator
This module is a modulator/demodulator. The top four knobs interact with each other to take a signal and mangle it beyond all recognition, or if you're patient and lucky, let the signal come through mostly unchanged.
What is going on there? you ask. The input is used to frequency-modulate a VCO that can oscillate beyond anybody's hearing range. The resulting (possibly ultrasonic) signal frequency-modulates a second identical VCO. This leads to the kind of signal degradation you might expect from an AM radio transmission. Or a short wave signal fighting its way through a hurricane.
The rest of the knobs control filtering; high-pass to remove the truly ground-shaking rumbles the top for knobs can generate, and resonant low-pass to get the harsh high pitches out of the signal, and emphasize (for example) the frequency range of human speech, if you want to pass old movie dialogue through this.
Also included are a wet/dry control (while prototyping this module I would sometimes spend minutes looking for the perfect knob settings to allow a signal through just to realize the signal source had stopped playing), a CV input for the low-pass filter with an attenuator knob, and a effect volume knob.
Some fun things to try:
with zero input, try to get a modem sound!
connect a simple waveform and massage the top four knobs to fold the wave in surprising ways
David Lynch. Put David Lynch through this.
turn the resonance of the low-pass VCF up and use this as a VCO (not 1V/oct, I'm afraid
Turn both "Carrier" knobs all the way down, so the VCOs are stalled, and listen to the signal bash its way through
"A short update on the browser based Nord Modular Editor that I am currently working on as a fun hobby project."
Additional details via https://nordmodulareditor.com where you can try it out yourself if you own an original Nord Modular:
"Nord Modular G1 Editor
Create, edit and (soon) share your Nord Modular patches with the community.
Some quick remarks:
This is still a very early version. A lot of things don't work or don't work correctly yet. You should be able to edit patches, browse slots, add modules and cables, adjust parameters and load patches into a slot. You probably want to run this in the Chrome browser, i haven't tested others. I have only tested this with a Nord Modular Keys for now, I assume the Rack version will work the same but I don't know about the Micro. I assumed it would work the same but it appears that some people have issues getting it to connect. Parameter values are often shown as their raw 0–127 values. None of the displays work yet. When something is wrong, updates don't come through, or communication seems to be stuck: refresh the page. When using a trackpad, you probably want to use "scroll to pan" navigation. You can select this in the settings. To add a module, drag it from the toolbar on top. To delete a module or cable, select it and hit delete. The tab key in the editor will toggle rendering cables behind or in front of the modules. If you were following my personal YouTube channel for updates, please follow my other channel instead. Feedback is much appreciated, but I don't have a proper way to do that yet. This is a personal hobby project. I am not affiliated with or connected to Nord in any way. Peter van der Noord"
"I turned a rare 1980s Texas Instruments toy synth - the 'Speak & Music' - into a full virtual instrument. Here's the demo and a live track built entirely with it.
This little plastic relic from 1981 has one of the most unique lo-fi tones I've ever heard: wobbly oscillators, crushed bit-depth, and a raw analog character that no modern synthesizer can replicate. So I sampled every note, every texture, every glitch — and built a playable virtual instrument from scratch.
───────────────────────────────── WHAT'S IN THIS VIDEO ───────────────────────────────── → Overview of the original Speak & Music toy synth (1981) → Demo of the virtual instrument → Live track composed entirely with the virtual instrument and the real one → How this fits into lo-fi & ambient music production workflows → Where to get the instrument (link below)
Speak & Music Bundle with 3 other retro instruments : Gurmroad : https://alpfv.gumroad.com/l/forgotten... ───────────────────────────────── ABOUT THE SOUND ───────────────────────────────── The Speak & Music was part of Texas Instruments' "Speak & Spell" family — a range of educational toys with surprisingly musical internal hardware. Its built-in synthesizer produces the kind of retro, degraded, lo-fi tones that music producers have been chasing with vintage synth VSTs and lo-fi sample packs for years. This is the real thing, captured and made playable.
Perfect for: lofi beats, ambient pads, cinematic textures, lo-fi music production, experimental electronic music, and anyone who loves the sound of broken vintage gear.

"Listen the new Radical Frequencies Dual Retro VCO playing an arpeggio , showing all waveforms and making Pulse with modulation and Hard Sync between the vcos . It goes through the RF Mixer and then to Diode Dream Vcf as it suits this oscillator perfectly! #eurorack #modularsynth #radicalfrequenciesmodular #dualretrovco #drvco #diodedreamvcf #analogsynth"
"Handmade Dual VCO of discrete core capable of internal FM cross modulations - Hard sync and Ring Modulator
• Analog discrete saw core oscillators with Saw, Pulse, Triangle and Ring Modulation wave outputs.The sound is warm and fat, emphasizing odd harmonics for this big retro sound. My purpose here is to approach the sound of classic synths from 70s, that we all loved. • The SAW wave produces rich bass frequencies, sweet mids and smooth highs but overall, it is still well balanced across the full frequency range. The Triangle wave is almost perfect in shape with no buzzy hum sound. The pulse wave can produce that chorus-like phasing effect, when using an LFO to modulate the PWM input and does so in a very unique way, as it changes the phase of the signal as well. • Two identical VCOs : VCO ALPHA and VCO BETA, with the ability of hard sync as each VCO syncs internally with the other. Using the attenuator knob for SYNC, you can go from zero to soft sync(11-12 o’clock) to hard sync when the knob is fully CW. For syncing you just need to turn CW, the sync knob of the VCO you want to be the slave. Don’t open both the sync knobs at the same time unless you want to make some weird sounds. • There are external sync inputs for each VCO as well. External oscillators can be used as masters, just feed the output of the oscillator of your preference, into the sync input or either ALPHA or BETA. Just remember to feed a saw or a square wave, into the SYNC input. This is very important in order to sync the oscillator. A ramp wave it will not sync at all! (The RF DPVCO for example is a ramp out VCO and if you want to use it as master you must invert the signal first.) • Both ALPHA and BETA track 5 octaves accurately, tempco resistors are attached to the tuning ICs CA3046 on both VCOs. Separate voltage regulators for each oscillator can achieve the best sounding results without drift or bleed pitch, between VCOs. • Both VCOs go from a relative fast LFO range with the coarse tuning knob fully CCW, up to high frequency oscillation. • Octave Switches of 3 positions: 1 octave down - , zero , 1 octave up +, are available and make patching, fast and intuitive. • There are internal normalisations for exponential as well as linear FM and both have independent EXP FM and LIN FM, attenuators. • You can select the wave for the internal FM buss via the front panel switches .Options are Triangle and SAW. The internal FM wave, is independent per VCO as well. • There are also internal normalisations for PWM, where each VCO modulates the pulse width, of the other and both use the triangle waveform. • There is a PW offset, per VCO - negative phase pulse width at CCW to + positive phase at CW and 50-50 duty cycle square wave, in the middle of the knob. • Ring Modulation section is a separate feature where X and Y inputs are internally connected with the VCOs as well. It has 2 inputs, X and Ψ and one out, RM. The inputs are internally connected to the internal FM buss switch of triangle - saw selector. VCO ALPHA is internally connected into Ψ input and VCO BETA, into X input. You can feed the RM inputs any wave you desire from other VCOs as well . • An external patch cable breaks the normalisation of all internal connections, via input jacks. (EXP FM, LIN FM, PWM, SYNC, X Ψ)
• Important note about tuning : The vcos need at least 30 minutes warm up before using it for good tracking. Also when you have to tune the vcos it’s better the octave switches to be in the middle position and all the fm and sync knobs must be closed (CCW)
• Large range of sounds with countless sweet spots - ultra stable tuning for FM sounds by using the FM and SYNC knobs simultaneously - fat basses, classic leads and drones. Feed the DRVCO into a good filter and you will enjoy it as it was meant to be! The VCF that I suggest is the RF Diode Dream VCF as it is a ladder filter and suits it perfectly! Of course any other filter of your taste can be used with great results."

"Here we have SUMP PUMP from Robots Are Red (with circuit design from Setonix Synth). It's a 6HP stereo Eurorack noise gate that can also invert its behaviour into a compressor and with the 'floor' control it can also be an expander. We've 3 umbrella sections in the video with compression, noise gate and sidechain ducking techniques. Check out the patches and let us know which is your favourite. There's also an exclusive run down of the dirty bass patch on / divkid"

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.

"Rain beat against the grimy glass of my office, as if the darkness itself were trying to force its way in. I sat, leaning against the battered back of my chair, watching the city drown in this invisible energy. They called it dark matter, but that was just a word, a pathetic attempt to describe something that had long since ceased to be mere matter. It breathed, pulsated, permeated the edges of reality, distorting the angles of perception and memory. People changed, became... different. Not evil, not mad, but simply *not the same*. Their faces seemed to blur, losing their clarity, until they became masks reflecting something ancient and alien. I saw it absorbing light, not simply extinguishing it, but reprocessing it, turning it into something new, something that defies description. And I knew that sooner or later she would get to me, swallow me up in her bottomless dark ocean, turning me into another brick in the foundation of something incomprehensible, something that would come when the universe got tired of being the universe.

"The "pairing series" is back! In this one we explore the Zakal, a spring reverb / feedback device from Colossus Audio. We start by using the Metal Fetishist as a sound source but quickly flip the tables and use it as a sound processor instead, making Rythms with the feedback tones that come through its input from the Zakal.
The background noise you may hear comes from my microphone, not from the instruments. I will be more careful next time.
"Zakal is a resonant audio feedback instrument. It generates feedback using reverb springs, with the feedback signal shaped by a low-pass filter and a delay in the feedback path or simple feedback. Additionally, Zakal can function as a spring reverb effect, offering versatile sonic possibilities.
Zakal contains amplification and recovery circuits designed to generate audio feedback through its reverb springs.
A switch allows you to engage the LPF and Delay within the feedback path, enabling creative control over the frequencies fed back into the spring reverb, shaping unique resonant textures.
When used as a spring reverb effects unit, the POST EQ provides precise shaping of the wet signal, offering enhanced tonal flexibility.
At the end of the chain, a 3-band EQ provides additional shaping of the output, offering precise control over the final sound. When used as a spring reverb effects unit, the EQ enhances the wet signal for even greater tonal versatility.
ZAKAL does not include a power supply. It operates on a standard 9V DC (negative center, 2.1mm barrel plug) compatible with most guitar pedal power supplies. If you do not own one feel free to reach out, and I’ll help you find a suitable option."

"Cold sand creaked beneath limbs I couldn't remember having acquired. Metal and flesh, woven into an inconceivable construct, pulsed with a dim, inner light. The planet was dead, scorched to the bone, only rusted rock and endless dunes on the horizon. I didn't know who I was, what I was, or how I had ended up here. My memories held only fragments of alien sensations, echoes of long-forgotten knowledge that didn't add up to a coherent picture. I was a mechanism, not crafted by hand, but grown like a mushroom on the rotting wood of space. My purpose? Nonexistent. My past? Emptiness. I simply wandered, driven by an instinct I couldn't explain, across this lifeless land, like a ghost forgotten even by death. And with every step, with every breath, I felt this planet, this emptiness, creeping into me, erasing the last vestiges of what could have been.

"Diogenes' Lantern" is a 12-voice drone synthesizer. However, it is capable of generating noise, ambient textures, and melodies alike. The synth features a unique control system designed to eliminate the need for a thousand knobs to manage every parameter; instead, it works as follows: One knob sets the value for the first oscillator, while a second knob determines the *offset*—how much the value of each subsequent oscillator differs from the one preceding it. This method is used to control all parameters: frequency, waveforms, and signal combination types.

Features: 12 oscillators with adjustable waveforms 16 waveforms that morph smoothly into one another 8 signal combination schemes (for pairs of signals) that morph smoothly into one another 3 filter types with resonance (HP, LP, Res) Filter LFO with selectable triangle, square, or oscillator/combiner-derived waveforms A second LFO featuring complex waveforms, capable of modulating synthesis parameters—including the filter (providing two dedicated LFOs for the filter) Tone quantization capability (quantizing to the tonic or fifth) 6-button keyboard interface; individual keys can be custom-configured, or a layout can be selected from 63 presets Attack, Release, and Glide controls Killswitch with smooth fade-out/fade-in functionality Randomize button, allowing for independent randomization of synthesis parameters and LFO settings "Move" mode: each key is assigned its own unique synthesis preset Polyphonic mode with 6, 4, or 2-voice polyphony Support for 432 Hz tuning Distortion effect Smoothly adjustable "Mass" parameter ...of sound, where the number of operating units can be regulated.
"What happens when a synthesizer completely breaks the rules? In this video, we explore the Genki KATLA — a truly unique polysynth inspired by Icelandic volcanoes, featuring a rotating voice architecture, hybrid signal path, and some of the most unpredictable sound design possibilities I’ve come across.
This isn’t your typical analog polysynth. Each of the five voices can run independently with different waveforms, octaves, and modulation — creating evolving textures, harmonic movement, and generative-style sounds that feel closer to modular synthesis than traditional keyboards.
🎛️ What makes the KATLA special? • Rotating voice polyphony (round robin-style synthesis) • Independent per-voice oscillators & tuning • Digital oscillators + analog filter signal path • Looping envelopes reaching audio-rate modulation • Phase distortion, wavefolding & multiple distortion types • Tape-style wow, flutter & pitch instability effects • Stereo voice movement & evolving spatial modulation • External inputs for processing other gear
From lush ambient pads to aggressive, evolving sequences — this synth can go places most instruments simply can’t. It’s not about recreating vintage sounds… it’s about discovering entirely new ones.
💸 At around €5000, this is definitely not a beginner synth — but for sound designers, and anyone looking for something truly different, it well worth a look."

"Hey guys! Very very excited to be presenting the Genki Katla to you all... I am truly in awe of the sound of this very unique and powerful instrument.
I thought the best way to get to know the synth is to start from scratch so in this video we'll go full hands-on with the Genki Katla, exploring (almost) every parameter and building sounds from an initialized patch.
From some raw drone layers and gritty textures to evolving pads, rhythmic sequences, and atmospheric beds, we will see just what this instrument can do, discover new sounds, and maybe make some friends along the way 🙏
If you're into sound design, unique synths, or just love discovering new instruments, this one is for you!
HUGE thanks to Genki for letting me a part of this with them and showing off this super cool synth.
No money was paid, no agreements were made... these are my real thoughts on this very premium synthesizer and I will be sharing lots more."
Press release follows:
Genki Instruments announces availability of Katla as Voice Rotating Polyphonic Synthesizer inspired by its natural namesake
REYKJAVIK, ICELAND: having twice blown European musical minds thanks to show-stealing showcases at SUPERBOOTH25, May 8-10, Berlin, Germany and Machina Bristronica 2025, September 27-28, Bristol, UK, before adventuring across the pond for a repeat performance at Buchla & Friends 2026, January 24-25, LA, CA, USA, Reykjavik-based instrument developer Genki Instruments is proud to announce availability of the eagerly-awaited Katla as a Voice Rotating Polyphonic Synthesizer inspired by Iceland’s largest subglacial volcano as its natural namesake — readily representing the company’s first foray into analogue synthesis, albeit one that uniquely utilises a set of wildcard parameters to infuse it with organic, unpredictable behaviour as an instrument that is worthy of that legacy, excelling at generating rich, evolving, multi-layered textures, where each note stirs, swells, and erupts in its own distinct way — as of March 31…
Clearly Katla’s inspiration runs through its ‘volcanic’ veins. After all, it is framed by side panels and knobs forged from authentic Icelandic lava, giving each instrument a tangible connection to the volcanic forces that inspired it. That this synth should surely roar is a given. Genki Instruments inevitably chose, therefore, to kit Katla out with four independent distortion destinations, the most unruly of which is a stereo CMOS (Complementary Metal Oxide Semiconductor) Drive effect — a characterful saturation stage, pushing tones from warm and rounded to fractured and snarling.
