Zlob Modular - AttMix

Three channel summed attenuator and mixer in 4HP
Each channel is normalled to the sum(VI) so it can be used as a 2 channel mixer and 1 channel attenuator, or a 3 channel mixer, or as 3 separate attenuators. Normalization to the sum is broken by inserting a jack into the outs of channels I-III. The Attenumixer works well with both cv and audio, although the potentiometers have a linear response. Since the module is passive there will be signal loss at the sum out. Here is a video about it.

Zlob Modular - Diode Chaos

Chaotic voltage generator in 3HP

It is a unique module because it has never existed as an electronic music instrument until now. The module is based on a circuit from a paper called “A simple chaotic circuit with a light-emitting diode” written by Volos, Wang, Jafari, and Kapitaniak.

Diode Chaos produces 3 phases of interrelated morphing voltages including a chaotic trigger out. The range is 20-30 seconds a cycle up to audio rate, although only the X out and TRIG out go up to audio rate. The frequency is controlled by the RATE knob. Each output exhibits different behavior at different rate settings. X,Y, and Z outs like to stay in the 4vpp range although at different RATE settings the outs can reach 10vpp. The TRIG out chaotically releases 0-10v triggers although sometimes it will spit out smaller voltage peaks.
LED soldermask windows provide constant display of positive and negative voltage crossings. Differences between chaos and random (some quoted and summarized material from Ian Fritz’s site) chaos is “highly irregular, but still contained within a finite region (the “strange attractor”)”. Chaos occurs in 3 dimensions chaos needs a non-linear element (with Diode Chaos the nonlinear element is a red LED, and the chaos is directly visible and useable at the TRIG out).

 

Here is a video about it.

Zlob Modular - Dual VCA

Dual summed voltage controlled amplifier and mixer in 2HP
It is a DC coupled OTA(LM13700) Dual Linear VCA based on the same fabled design of the VnIcursal VCA. The 2 VCAs are summed together so it can be used as a voltage controlled mixer at the “SUM OUT” or all 3 outs can be used separately and simultaneously. 5 volts into the CV in will provide unity gain, anything above 5 volts can clip the input.

Zlob Modular - Dual VCO

Dual voltage controlled analog oscillator in 4HP
Each VCO has square, triangle, and sine wave out, coarse and fine tuning controls, a control voltage input, and a switch for selecting exponential or linear cv in. When a control voltage is inserted, the fine tune control becomes an attenuator for the incoming voltage. In exponential mode, when the attenuator is fully clockwise, the VCO will track around 5 volts per octave. Here is a Video about it.

Technical Information
4HP, 45mm Depth
20mA +12V/40mA -12V
Reverse Power Protected
Waveform outputs 10vpp

There are a couple quirks to these 8038 VCOs: Below 300 hz the waveform symmetry is slightly off. Triangle waves get a little uneven in the lfo range, the sine is not completely perfect to begin with the bottom trough and in the lfo range it slopes slightly, and the square turns more trapezoidal above 1khz (see scope shots). Also it doesn’t track 1 volt per octave perfectly. Usually the 1st and 3rd octave will be a couple cents off. Other than those idiosyncrasies, it is a powerful, stable dual oscillator in a small footprint with no cross talk between oscillators. It’s great for: drones and beating sine or triangle waves, cross modulating itself for interesting clocks/LFOs, creating complex waveforms/timbres through lin/exp frequency modulation.

Zlob Modular - Entropy

Analog random voltage and noise generator in 3HP
It features sample/track and hold normalled to white noise with a toggle switch for selecting sample(switch right position) or track(switch left position) and hold function. There is also a PCB trimmer(at the top of the motherboard) to adjust the spread(gain) of random voltages out from “scalar” (low gain, counter clock wise) to large interval jumping(high gain, clock wise). All analog white, pink, and brown(red) noise 10vpp~(dependent on lower PCB trim). Smooth(infra red) random cv out at 10vpp with 2 range settings from wiggly with (more events, switch in left position) to almost random rise and fall envelope behavior (less events, switch in right position). White noise pcb trimmer sets the amplitude of the noise which in turn influences the rate of the infra out. LED solder mask windows indicate positive(red) and negative(blue) voltage crossings. Here is a Video about it.

Zlob Modular - Entropy Expander

Analog random voltage and noise generator that expands upon the features of the Entropy Euroack Module in 3HP
The Entropy+Expander packs together some of the most random voltage options in 6hp. It provides a controllable “Glide”(slew) out for the S/T\H, a comparator with a controllable rate(“Thrsh”) of random gates(“Rand Gate”) out with an input to compare other waveforms(Comp In, inserting a cable into here breaks the white noise normalization), and high pass filtered white noise resulting in approximate “Blue noise”(+3db/octave) and “Violet noise”(+6db/octave) outs.


The unique part of the circuit is a voltage controlled  A/B switch thats normalled to the “Rand Gate” out that’s switching between the S/T\H out(left Blue led window)and Infra out(right Red led window), the Glide control also effects the S/T\H coming out of the switch so you can get really random results from the “Entropy Out.” Inserting a cable into “Switch CV In” breaks the random gate normalization and lets you toggle between A/B(left S/T\H out and right Infra out, indicated by the led windows) with your own gate or trigger.

There is a jumper on the pcb to select if you want glide on the s/t\h at, Entropy out, or un-slewed operation. There is also a trimmer for setting the amplitude of the incoming signal at “Comp In” which sets the frequency range of random gates. This may have to be adjusted depending on your Entropy version.
The random gate range can also be set up more as a noise oscillator by turning the pcb trim(clockwise) up or it can be set so random gates are extremely slow(trim counter clockwise) with minutes between random gates.Here is a Video about it.

Zlob Modular - MinEQ

Simple 3 Band Equalizer in 2HP
It provides boost or cut control over the Low, Mid and High frequency bands of an audio input. The circuit is capable of up to 20vpp~ of boost(with a 10vpp signal) and attenuation down to 1-2vpp depending on the input. The frequency bands are centered near 50Hz(Low), 1kHz(Mid), and 10kHz(High). The circuit is AC coupled and will invert the input. With all the potentiometers at noon, the MinEq passes the signal relatively unaltered.

Zlob Modular - MiniAtt

Dual summed mute Attenuator, Offset Generator, Mixer, and Mute in 2HP

The newest 666 version (available late August 2020) can be powered and will provide Offset of 0-5V with nothing plugged into the “IN” for each channel controlled by each respective Potentiometer. The “Sum Out” will also be able to send out 0-10v~ volts depending on the setting of each Potentiometer. Both channels are normalled to the sum, so inserting a signal into an “IN” will remove it from the “Sum Out. There will be signal loss at the sum out, because the module is passive. Great for cv or audio although the module ships with linear pots. Here is a video about it.

Zlob Modular - Push VCA

The Push VCA is a 2 Channel DC Coupled Mute Eurorack Module in 2HP
It features 2 independent unity gain DC coupled VCAs with led push button mutes. A mix of both channels is available at the sum, but all outputs are available simultaneously. The newest version has normalizations to +5v, so with nothing plugged into the ins voltage can be toggled on and off at the outputs and up to 10 volts can be output at the sum. At checkout specify if you want latching or momentary push buttons. LED button color may vary between red and yellow. But it will always be 2 of the same color. A Video can be found here.

Zlob Modular - Skew-Fade LFO

Analog skew-able xfade-able LFO Eurorack Module capable of a plethora of waveforms in 3HP
It has three rate settings ranging from 3 minutes and 30 seconds a cycle up to audio range at 20 hz. Triangle waves can be skewed between ramps and saws, and square waves pulse width can be adjusted from inverted triggers to triggers. The LFO’s unique feature is voltage controlled cross fading through the (“Fade C.V.” in) between square/shark tooth\sine waveforms provided at the “Fade Out.”  All outs are also influenced by the skew knob resulting in many complicated and asymmetrical possibilities at the “Fade Out.” It can even be self patched(ie triangle or square into fade cv) for an extended pallet of waveforms. The “Fade C.V.” in expects a bipolar voltage 10vpp to fade from square to sine with the fade pot at noon position. Bicolor led provides constant display of positive and negative voltage crossings. Here is a Video about it.

Zlob Modular - SVF

The SVF 2 pole 12dB State Variable Filter Eurorack Module in 4HP
It provides Low Pass, Band Pass, and High Pass outs inspired by WASP and Thomas Henry filter topologies. The filter has 2 audio inputs, but channel 2 is jumper selectable between standard audio in or Ping-able operation. The 2019 revision also adds improved cutoff and resonance response and attenuversion through the ACV IN using the above pot. CV IN provides another unattenuated voltage input to modulate the frequency.
At the CV in, +10v will open the filter completely if the cutoff pot is CCW(counter clockwise). With the cutoff knob at noon the filter can be opened with +5v or closed with -5v. CV input at the ACV in is dependent on the CV attenuverter knob.

There are also several jumper selectable modes for max resonance, self oscillation or no oscillation based on the setting of the resonance pot.  According to the jumper configuration, the filter is capable of clinical and clean, to juicy and drippy, to low pass gate sounding plonks, to screaming chaotic resonance. When set to self oscillation mode, the filter can produce a sine like wave with no input and a trapezoid like wave in the max resonance jumper setting. In max resonance mode, the filter output can exceed 10Vpp. On the newest version, there is a trimmer on the top pcb to set the lowest cutoff frequency. Here is a Video about it.

Zlob Modular - VNICURSAL VCA

The VnIcursal VCA is an 6 Channel VCA Eurorack Module in 8HP
It the smallest, most compact Voltage Controlled Amplifier in the Eurorack market. It provides 6 OTA(LM13700)-based DC Coupled Linear VCAs for Audio or CV. The 6 VCAs are summed together so it can be used as a voltage controlled mixer. Each VCA is normalled to the sum so they can be removed from the mix and used on their own. The potentiometers control the amount of gain, and when a voltage is inserted into the CV in the potentiometers act as attenuators. With a control voltage of 5 volts the VCA will be at unity gain, anything above that can clip the input. LED brightness with or without CV in provides constant feedback of each channels amount of gain.
The VnIcursal is not a perfect scientifically spec’d VCA. Analog VCAs can only close so much, or be so silent. In certain situations based on power supplies and gain stages the VCA can experience some bleed or noise mainly at the sum out as all channels are passively summed then buffered.
