"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.

New Zlob Modular Miniatt v666 Overview by J.Soliday

"Here's a pretty in depth look at all the uses of the new powered Miniatt by Jason Soliday.

The new Miniatt can now: offset, attenuate, mute, level shift and actively mix for more info and specs

built:$50
kit:$35
pcb/panel:$15"

"MiniAtt is a 2hp Dual Passive Attenuator, Offset Generator, Level Shifter, Mixer, and Mute Eurorack Module available as a Eurorack DIY Kit, PCB and Panel, or Built Module.

The newest 666 version(2021) 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 “OUT” will remove it from the “Sum Out.” Likewise, when inserting a cable into the IN it will remove the voltage normalization and act as a passive attenuator. In active mode the module can also be used to offset and level shift +5v to -5v signals to 0v to 5v(and other ranges in between) at the “Sum Out” with a waveform input on one channel and by using the normalled voltage offset from the other channel.

There will be signal loss at the “Sum Out” in passive mode. In active mode the “Sum Out” is buffered and there will be no signal loss. Great for cv or audio although the module ships with linear pots.

The new black and white pcb/panel is reversible meaning, one side is classic(first picture) and the other side is soulless(second picture).

The module should not be powered when the jumper is closed for passive mode."

New Zlob Modular Glow-in-the-Dark Patch Cables

via Zlob Modular

"Żłob Glow in the Dark right angle Y Splitter/Multiple cables are available now! They come in 3 packs or by the single cable in 4”(10cm) Male to Female/Female and 12”(30cm)and 18”(45cm)Male to Male/Male.

currently they are only available through my site, but 3U-Shop in Germany should be getting some in a couple months.

Prices are
4”(10cm) Male to Female/Female
$6.25 for 3packs
$2.25 for single

12”(30cm)and Male to Male/Male.
$6.50 for 12” 3packs
$2.50 for 12” single

18”(45cm)Male to Male/Male.
$6.75 for 18” 3packs
$2.75 for 18” single

These are a great cost effective low profile alternative to stackcables and make it way easier to close patched tight cases while still multing signals.

"The VnIcursal VCA is an 8hp 6 Channel VCA Eurorack Module available as a Eurorack DIY Kit, PCB and Panel, or Built Module.

It is 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 also be used as a voltage controlled mixer. Each VCA out is normalled to the SUM out so they can be removed from the mix and used on their own, they are not cascaded outputs. 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 around unity gain, above 8v can clip the input. LED brightness with or without CV in provides constant feedback of each channels amount of gain.

The newest VnIcursal version 666 now uses mostly resistor arrays(meaning multiple resistors in one long SIP package) as opposed to 90+ single resistors with v5. Upgrading to resistor arrays greatly simplifies the build and reduces the build time by 30 or 40%. Now the VCA is much more DIY friendly with new detailed build docs and should have less part placement headaches resulting in overall less troubleshooting and problems.

Version 666 also reduces bleed and cross talk sometimes apparent with version 5. But keep in mind 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. Inputs above 1K Hz will experience more bleed than lower frequency signals.

Also version 666 now comes with all red leds.

Optional Knobcon Banquet only $50

It all begins with an opening reception on Friday, September 9 with live performances by Allerian, Entanglement, Studio Dummies, and Suit & Tie Guy. Attendees of the reception will also enjoy specially priced drinks featuring whiskey from Balcones Distilling.

Multiple exhibit halls open to the public at 10AM Saturday and Sunday and are filled to capacity with large manufacturers such as Roland, Korg, Yamaha, and Moog, the finest boutique modular and pedal companies, and even some "classic cars" that collectors bring to display. Behringer’s new analog polysynth DeepMind12 will be making its North American debut at the event. Also appearing will be the new Minimoog Model D from Moog, and Arturia's Matrixbrute. See the latest releases and even purchase gear at special Knobcon pricing throughout the weekend!

Workshops scheduled on Saturday and Sunday, Sept 10-11. See the Knobcon website (www.knobcon.com) for complete descriptions and times.

Saturday evening features multiple events including the annual Knobcon Banquet with a keynote address by guest of honor, Bill Hemsath. Enjoy cocktail music by the Knobcon Supper Club All-Stars, a classic organ, guitar, and drums trio.

Bill Hemsath, RA Moog's Chief Engineer from 1969 to 1971, gave us three fantastic things we all treasure to this day. He developed the first CV joystick, which then became pitch and mod wheels. He also had the bright idea to wire some modules together in a box with a keyboard, and the Minimoog was born.

The entertainment continues Saturday night with multiple live music events. The Knobcon Big Room - a house and techno party with projections by Lorenzo Vektor and Dennis Stein. Big Room performers include Glacial 23, Introvert, Low-Gain, Komprezzor and Oliver Dodd. If that's not your thing, head over to the International Players Club - a live music and jam session with The SynthFreq & Friends.

Knobcon ends on Sunday, September 11 at 5pm.
