"Kevin of Chicago-based Żłob Modular gives us a tour of his latest modules. There is a prototype expander for their existing SVF Filter module; and the Trepanator, an 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.

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."

"**BEWARE OF BLOOD AND BONE FRAGMENTS PROJECTION**
Freshly built kit. Zlob Modular TREPANATOR is a 'bent by design' module, inspired by the great Benjolin from Rob Hordijk, but quite different.
First encounter with this thing, with just a bit of white noise into the filter, it was WILD!

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.
