"I made some beats and generated noise using only the Hikari Instruments Triple AD.
The Triple AD features standard envelope mode and cycling mode, and can also be controlled by incoming trigger (voltage) timing.
By combining its LFO and envelope functions, you can enjoy a full performance with just this single module.
It’s easily the worst—and coolest—way to use an envelope module imaginable!
#eurorack #eurorackmodular #envelope"
Triple AD from Hikari Instruments provides three independent Attack/Decay envelope generators in an uncommonly tiny Eurorack footprint. Each of the envelopes has a dedicated trigger input and an output.
All envelopes can be set to self-cycling mode either manually via a switch or using control voltage or gate signals sent into the cycle input jack, extending the module's utility into LFO-like territory. Additionally, above each of the outputs, there is a 3-position range switch, enabling access to envelope times from 0.2 ms to eight seconds in length.

Per-channel cycle mode may be activated manually or momentarily set via CV/Gate
"Gator Legio is a stereo supersaw oscillator inspired by the Manis Iteritas Alia core, with piles of detuned saws, phase modulation, and plenty of stereo movement.
Let's start with Detune. This spreads the saw voices apart in pitch, taking your sound from a tight unison to a huge, dense, swarm of saws.
Saw Mod changes the character of those waves, giving you another way to push the harmonics with that classic Noise Engineering sound.
Then there's Saw Count. This switch changes the number of saw waves in the swarm.
And since Gator is stereo, the Stereoness switch spreads those voices across the stereo field for an even wider sound.
The inputs are for phase modulation. Feed in another oscillator and you can take that supersaw into much stranger territory.
And send a gate to the 8vA input and Gator instantly jumps up an octave, giving you another fun way to animate a sequence.
Gator is one of several synth voices available for Legio. You'll also find AT, Plus, Unda, Reso, and plenty of completely different percussion voices and effects to swap in over USB.

"The hardware R2R Ladder Eurorack module is now available as a free virtual module, marking the first release in VAEMI’s expanding software line.
Istanbul, Türkiye – September 2026 – Istanbul-based electronic musical instrument manufacturer VAEMI – Volt Age Electronic Musical Instruments has released its first plug-in and first software product: R2R Ladder for VCV Rack.
The new virtual module is a software adaptation of VAEMI’s physical R2R Ladder Eurorack module, preserving the original hardware’s bidirectional architecture and core musical concept. The plug-in is available free of charge through the official VCV Library.
Inspired by the fundamental architecture of an R-2R digital-to-analog converter, R2R Ladder uses eight weighted connections representing eight binary bits. Together, these provide 256 possible binary combinations, opening up a wide range of applications for audio, CV, gates, modulation and waveform processing.

Powered by an ATmega328P microcontroller (standalone DIP-28 package) and a Spin Semiconductor FV-1 DSP chip, this module architecture bridges old-school analog synthesis with modern digital studio effects.
"Clave, Ecuclidean Drum Machine lets you intuitively play rhythmic patterns that complement and syncopate with one another. Prepare your compositions across 16 steps and 8 sample tracks by saving different versions or parts, and refine your performance with the included effects and filter. All in a single, lightweight, and portable unit. It comes with 5 factory-installed drum kits and has space for you to add your own.
It’s based on what’s known as Euclidean Rhythms, which describes the distribution of beat intervals. It sounds complicated, but that’s exactly what makes the system simple. The best part is that you’re not limited to using the automatic distribution system, you can also program it step-by-step, 'XOX' just like any other drum machine.
In our musical quest to create a hybrid sound that blends electronic music with organic rhythms, we have collaborated with percussionists, designed our own synths and drum machines, programmed digital instruments, and even built electromechanical percussions!
This campaign is to introduce our new drum machine to the world; we already have a couple of working prototypes. We need your support to be able to produce the first batch of machines. This is already our fourth project on Kickstarter—we hope we can crowdfund this one, too!"
The Dual Stereo Looper, released in July 2026, is a collaborative effort between P4L and Ambivalent Instruments.
It is a 2-channel stereo looper in Eurorack format.
In addition to basic recording and playback functions, it is equipped with features such as pitch shifting, reverse playback, filtering, and reverb. CV control allows for sound design characteristic of modular synthesizers.
In this video, we will take a deep dive into everything from the module's basic functions to practical applications using CV.

"A gentle IDM patch built entirely from one sequencer — Shoal by Ormer Modular, an 8-track generative melody sequencer now officially available in the VCV Library. Each track uses a numeric seed for a deterministic, repeatable pattern.
6 tracks feed FM synth voices (Bogaudio FMOp), 2 tracks drive drums (dbRackModules Drums), with Branches adding probability-based triggering. Everything passes through Chronoblob2 delay into a shared Valley Plateau reverb.
One clock. Eight evolving voices. Nothing loops the same way twice.
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."
If you came for metallic falcon screams, jump to 1:19. This unbranded 2050 module was made custom by Jakub Jasiński for the previous owner. It’s plugged in a 4ms pod, but it’s getting 5v DC externally. It’s not a clone, but it seems to have been based on the Zerosum Inertia 6550-99, which is probably the greatest voltage controlled oscillator of all time. The Ladik S-143 (through the U-202 and multiplied) is sequencing the 2050 tune input and pulse input, as well as the MFB OSC-2 CV1. The triangle on the OSC-2 is running to the sync input on the 2050. An envelope from the MFB dual ADSR is running to the 2050 drive input. The delay is from the Peavey DDL-3 and the reverb was blended on CXM 1978."
"In this VCV Rack tutorial, we take a deep look at Vult Overon, a complete synthesizer voice inspired by the classic Oberheim SEM architecture.
We’ll explore how Overon works, its two oscillators, state-variable filter, envelopes, LFO, VCA, internal modulation and normalled signal paths — and how to break those connections to use Overon in more modular ways.
After the tutorial, I’ll demonstrate a collection of presets and patches I made for Overon. You can download them and use them in your own VCV Rack patches.

"The 20CC TXX-1 Spectron is a Eurorack format dual oscillator inspired by vintage analog multisampling instruments such as the Mellotron, Chamberlin, and Optigan. Spectron uses a unique combination of synthesis and sampling techniques to bring the rich, warbly sounds of these classic instruments into Eurorack for the first time, while also offering new possibilities to manipulate, warp, and mangle them.
Analog multisampled instruments had their hey-day in the 1950's through the 1970's. They used analog recording technology - tape recording in the case of the Mellotron and Chamberlin, and optical sound printing on analog photographic film in the case of the Optigan. Each key corresponded to a recording of a note played on another instrument, often orchestral sounds like strings, woodwinds or choirs, which would play back when the key was pressed. All of Spectron’s sounds are based around full, per-key recordings of vintage multisampled instruments.
Rather than simply triggering discrete samples, Spectron organizes many samples to create the illusion of a continuous voltage-controlled oscillator. As pitch changes, playback seamlessly transitions between recordings, preserving the character of each original tape while allowing smooth, continuous frequency control.
There are two assignable timbre shaping sections not normally found on sample-based instruments: FM and Sync. These are tuned to range from subtle modulations that recontextualize familiar sounds, through radical transformations that are barely recognizable, and all the way to harsh and clangorous, with continuous CV control of all points between."

Sound is synthesized by a system of oscillators based on Schmitt triggers, that recreates the classic, complex sound of an analog cymbal. The sound is synthesized by a system of oscillators based on Schmitt triggers, operating at different frequencies. The mixing of these signals creates the rich, chaotic, and metallic spectrum.
You have direct control over the resulting texture. The TUNE knob shifts the overall frequency range of the metallic noise, while DECAY sets the length of the sound's wash and sizzle. The TONE control further shapes the character of the ringing, allowing you to fine-tune the brightness and timbre. This combination of controls lets you sculpt everything from a short, bright metallic click to a long, decaying noise.
For dynamic performance, the module features an ACC input (0V to +5V) to modulate the accent level and is triggered via the standard GATE input (+5V to +12V). The final, complex cymbal sound is available at the OUT jack.

"A versatile stereo audio-to-CV processor from Twang."
Crossfader/Polarizer/Panner with a twist.
CPP is a powerful processor for audio, but it also can be used with CV signals. It’s a great tool to work with a stereo field particulary and with a sound design in general. It can be a multitrack bus or individual panner. For small systems it can be end-of-chain mixing tool with vc crossfaders, vc panners and VCA’s.
The module consists of 4 sections: 2xCPP, Mid/Side, 2xVCA. The first two channels are identical and the module is named after them. We have two signal inputs going to the crossfader, controlled with the knob and cv input. Additionally, there is a handy attenuverter to make cv control easier. After crossfader the signal goes to polarizer, which is actually a bipolar VCA and can be used as classic amplifier, ring modulator or inverter. It can be bypassed symply by routing the signal with switch directly to panner, then it can work independently. There is a dedicated input C for it. Thus we can get 3 input mixer inside one channel. In addition, it has 5V offset switch wich can be useful while processing a cv signals. The final stage is panner. It also has cv input and send our signal to sum in stereo.
The second channel is identical to the first one.
The third section is a “secret weapon” of stereo sound design – Mid/side encoder-decoder. L and R inputs are transforming to Mid and Side signals and then can be transformed to wide stereo field. There is no knobs to control this, but there a lot of ways to use it with other on board sections or with other VCA, VCF or FX modules.
The last fourth channel is a pair of VCA’s. There is a signal input, cv input and signal output. Both are the same and have level control knobs.
Finally, all input signals are summing to master output with deficated level control knob. If we use a channel’s individual output, it will be subtracted from the main mix.
