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.

Info, manual and more // https://zlobmodular.com"

"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."

Zlob Folidplier wavefolder - sine edition

video upload by John Schussler

https://zlobmodular.com/

"In my last video I did a comparison with the Zlob Foldiplier [posted here] that involved me using a saw wave as the input audio source.

It was pointed out to me later on ModWiggler that in fact, that's not the best idea. What you really want to do with wavefolders (and distortion) is to use a simple wave like sine or triangle, so the folder can add more magic, particularly on the low end. High-harmonic-content waves like saws are already so busy that you don't get as much of the juice out of the 'folder.

So let's try this again, but this time with a sine wave. Note that I'm not doing the AI Synthesis Wave Animator in this one since it's not technically a wavefolder, and the input wave doesn't matter. I am, however, adding in the Joranalogue Fold6, because like the Foldiplier it's 4hp, and it's currently my favorite.

Let the competition begin....

Two New Waveshapers - August 2023

video upload by John Schussler

"New month, new modules.

I built the Wave Animator from the kit: it's very straightforward with a small part count and easy assembly.

I most certainly did not build the Foldiplier. It's got lots of parts and does not look to me like an easy project. (Zlob's web page rates its difficulty at 3.5/5)

They're both waveshapers, but with very different approaches. The Wave Animator is based on an Ian Fritz design that produces two pulses whenever it sees an input wave. The Foldiplier is a more "standard" wavefolder/harmonics generator, with the caveat that it has a feedback mode best described as 'pissed off.'

Both are quite fun.

Zlob Modular Folidplier

video upload by Żłob Modular

"A basic overview of the wave folding and feedback capabilities of the Foldiplier. Sine wave input in and using the low harmonic setting for the feedback switch."

via Zlob Modular

The Foldiplier is a 4hp odd/even harmonics generator with 2 different oscillating feedback paths. The folding core of the design originates from the odd harmonics (middle)section of the Serge Wave Multiplier. But the Foldiplier adds voltage control over the symmetry and offset as well as a switch for feedback, jumper selectable between, a transistor based oscillating fuzz inspired by the Hemmo Bazz Fuss with a lot more low harmonic content and a passive oscillating half wave rectification circuit with more high harmonic content. When these feedback oscillations mix with an incoming waveform some unpredictable and unique nonlinear timbres can be achieved. The module can also be used as a no-input experimental oscillator with the feedback switch engaged. All diodes in the module are silicon.

The Fold knob controls the amount of times the waveform is folded in on its self (indicated by the red led window below the knob). The C.V. knob below is an attenuator for incoming control voltage corresponding to the Fold jack(indicated by the red led window above the jack, it only responds to positive voltage). So, the Fold knob acts like an initial amount of folding depending on its position. For example, with the Fold knob fully clockwise you can get even more folds with a control voltage in at the Fold jack. The Offset knob controls how much positive DC voltage(0 to 5v, clockwise) or negative(0 to -5v counter clockwise) DC voltage(indicated by the led window above the Offset jack, red for positive, yellow for negative) injected into the waveform via the Symmetry knob. With the Offset knob position at noon(0v) there will little effect from the Symmetry knob. The Offset jack is expecting +5v to -5v with knob position at noon to scan through the positive and negative voltage. The Symmetry knob controls the amount of negative or positive offset voltage(dependent on the Offset knob) mixed with the waveform(indicated by the yellow led window above the Symmetry jack). If positive voltage is mixed with incoming waveform more folds will occur on the positive troughs of the waveform, likewise, when negative voltage is introduced more folds happen on the negative troughs. This part of the circuit can also be broken down by thinking of the Offset as a voltage controlled crossfader swinging between positive and negative voltages into a VCA controlled by the Symmetry knob and jack. When a voltage is present at the Symmetry jack the Symmetry knob becomes an attenuator. The Symmetry jack only responds to positive voltage.

Eurorack: Building The Ultimate Vibe Machine

video upload by Soundology

"Vintage, analog, tape, and character galore, this is my latest eurorack system with a breakdown and of all the individual modules with sound demos. I also go into my reasoning behind them and how I made a system where the total is greater than the sum of the parts.

I was fully intending on getting out of eurorack upon the realization that nothing I had built up until that point really compared with my favorite semi modulars, the Moog Matriarch and the Korg MS-20. I had also tried to make grooveboxes, but nothing compared to my Digitakt. But after selling almost all of my excessively huge collection of modules and synths, I thought I'd give it one last ditch effort..."
