An Experimental “Bent by Design” Synth Voice // 3 Patches with the Trepenator from ZLOB

video upload by DivKid

"Here we have the TREPANATOR from ZLOB, which is an experimental "bent by design" synth voice. It's inspired by Rob Hordijk's Benjolin and ZLOB remaking similar ideas with their own modules and circuits. There's two oscillators, a multimode filter, many feedback points, oscillating 3 band EQ and more in this highly interactive and wide ranging abstract voice and instrument.

Like the Benjolin that inspires it, the Trepanator excels and abstract, organic and interactive self influencing textures, sounds and rhythmic ever evolving loops. In this video there's mud burping, swamps in space caves, aquatic bubbles, harsh noise, unique techno percussion and FX and plenty more.

"The Trepanator is a 14hp analog “Bent by Design” experimental instrument featuring a Dual VCO, Difference Rectifier, 3-band EQ, Sample/Track and Hold, and SVF(state variable filter) all built into one nonlinear module. Its origins trace back to a love for Rob Hordijk’s Benjolin and patching a similar pseudo chaotic feedback-based instrument from scratch using all Zlob modules.

Although not based on Hordijk’s circuit or signal flow, it uses a similar architecture of dual voltage controlled oscillators, an “interference pattern generator,” a state variable filter, and internalized cross-patched feedback. Instead of a Rungler and comparator the Trepanator uses a sample/track and hold with slew, a difference/rectifier circuit(based on NLC), and a self-oscillating 3-band EQ. Utilizing this excessive feedback between the VCO’s, EQ, S/H, and SVF, creates a completely new instrument for discovering abstract electronic sounds. The Trepanator is a highly interactive, unpredictable, and an immediate instrument capable of a huge range of organic and sounds from: snarling, plucking, bubbling, screaming, gurgling, hissing, grunting, pinging, and quacking, to machine like rhythmic loops, circuit bent broken modem sounds, no-input mixer screeching, intermittent short wave radio fizzling, and full on Harsh Noise Wall all within the touch of a fader or a small knob turn without any external audio or any control voltage in."

"The Blippulator is now available at Nosiebug

https://www.noisebug.net/products/biy...

Meet blippulator, the quirky offspring of Rob Hordijk’s legendary designs, blending the heart of a Blippoo Box with the chaotic energy of a Benjolin.

Born from the mind of Hordijk's sonic explorations and further refined by Biyi, Blippulator takes everything we love about these classics and adds a fresh twist.

At its core, blippulator features extensive CV control, letting you dial in and modulate key parameters like the pitch of its two oscillators and the cutoff frequencies of its dual resonant filters. These aren’t just any filters—they’ve got that twin-peak magic that Hordijk fans will instantly recognise, adding a complex, organic edge to your sound.

One of blippulator’s coolest tricks? You can select any two arbitrary signals to create a custom PWM waveform, adding a layer of flexibility and unpredictability to your patches. Whether you’re controlling it from a Eurorack system or another external device, the 0-5V CV inputs and outputs make it a breeze to integrate into your setup. The panel is user-friendly, making it easy to get hands-on with your sound and improvise live.

And just when you think you’ve got it figured out, blippulator’s got a few secret weapons up its sleeve to keep things interesting in your performances. It’s a powerful tribute to Rob Hordijk’s genius, honouring his designs while pushing them in new directions, making it a must-have for anyone who loves modular synthesis and sonic exploration.

Blippulator is more than a synthesizer—it's a celebration of the past and the future of sound design, with a nod to one of the most innovative minds in the field. Plug in, experiment, and let it take your performances to the next level"

"Played some more with the ALA Monsoon this time - a drone from Moog Mavis is recorded into Monsoon after some wavefolding, and then put through some heavy reverb. A heavily (self-)modulated Maths is opening the VCA channel. The melody comes from ALA Beehive into the Void algorithm from TTA Zverb, while the aux out goes through ALA Benjolin (with the filter being modulated bei Benjolin's Rungler) and into pico DSP's delay.
The v/oct from ALA Steps quantized by Shakmat Bard Quartet, with the harmonies switched by RitS QUA through Noise Engineering Vice Verga. I used the trigger input on the Beehive for the first time, with the ochd expander providing the triggers.

RoaF Modular - Carol of the Oscillators | A Modular Synth Patch

video upload by ChiaroBen

"A variation on Carol of the Bells - the main 4 note melody always struck me as very melancholic for a christmas song, and I've been fascinated with it for a while now. This is my spin on it.

Pico VCO is playing the melody, while ALA Beehive is providing a bassline. Coloured noise into Benjolin as a texture filler, and sometimes little drum hits, which are also coloured noise from Pico Noise.

The melody gets put through Pico DSP delay, and then TTA Zverb - the Shimmer Pitch Adjust is one of my favourite reverb modes on that module.

Pitch info comes from Mimetic Digitalis, which gets put through Shakmat's Bard Quartet for quantization. Channel 2 provides the bass, with four different notes switched by the harmoy, which comes from RitS QUA's attenuaters put through Trace, swept by øchd expander.

Noise Engineering's Kith Ruina provides distortion for the bassline, and sometimes breaks up, which caught me by surprise, but I like to record my patches with errors and all, instead of slaving over a perfect patch every time - generative music is unpredictable in places, and that's what makes it organic.

Switching the bass notes with Vice Verga instead of Trace would've probably been less disruptive, but I decided against rerecording and keeping the track as is.

Happy Holidays, everyone. Remember - music is powerful.

It's a Rungle outthere | Cybernetics EP02 | From Benjolin to Blippoo Box

video upload by Cinematic Laboratory

"The Benjolin is a powerful module. For many, it's a chaotic noise source, which was exactly the point of the design. The Blippoo Box is less chaotic, more musical and designed as an experimental instrument. It's more a Pandora's Box. Both have the Rungler in common. It refers to a shift register circuit, but also to the 5U module that includes two VCO's and is not unlike the Benjolin's chaotic core. I do not own a Blippoo Box for obvious reasons (it's now priceless) but I do love my Benjolin. It's going to be a noisy video where I'll try the Rungler concept on Marbles and XAOC Leibniz.
Marbles is a cool extension to the Benjolin, and the Benjolin can also be a great conventional complex VCO.

Rob Hordijk designed the Rungler module (and circuit) to cover the space between a fundamental sinewave and the total chaos of white noise. A creative source of designer noise to enrich your patch. And wow, what a designer he was."

Exploring clocks, loops and chaos with Rung Divisions from Fancyyyyy Synthesis

video upload by Tom Churchill

"This video is about Rung Divisions, by Fancyyyyy Synthesis. It’s one of the most inspiring modules I’ve used recently, but it’s also quite a hard one to sum up in one sentence.

It has two main components. The first is a clock divider which outputs pulses that you can combine in two buses to create polyrhythmic patterns. That drives a universal shift register which outputs pseudo-random, chaotic or looping stepped voltage patterns. It’s an evolution of Rob Hordijk’s Rungler circuit, which is at the heart of the Benjolin synth. And there are dozens of interesting musical applications for it - a few of which I explore here.

Find out more at https://www.fancysynthesis.net/

NB: Fancyyyyy Synthesis sent me this unit to check out, but I don’t get any other sort of payment. This is a demo, not a review, and this channel is a hobby, not a job, so I only showcase things that I’m genuinely enthused about.

​Rung Divisions combines a universal shift register, a “divide by n” pulse divider, analogue noise, and several logic and binary operations. These functions synthesise an array of predictable and unpredictable digital signals at arbitrary time scale.

Rung Divisions’ primary use is as a complex polyrhythmic gate generator that drives a chaotic / pseudo random / looping stepped cv pattern generator, with voltage control over the pattern “direction”, length, and chance of the pattern looping. The combination of these features can be used to generate auditory illusions similar to a stroboscopic effect – like the visual aliasing of a wheel that appears to stand still and reverse direction at speed. Rung Divisions is built with solid state & discrete logic blocks to work at frequencies between 0–40kHz. The module is designed to drive multiple voices with gate patterns and CV, or to generate audio rate mayhem - these functions can be combined through patching with other modules that can take input signals over a wide frequency range. ​

Rung Divisions behaves in many surprising ways with feedback and self patching - the module has propagation delay compensation to allow for all outputs to be used in feedback loops.
