Serge VC Resonant EQ for Eurorack


video upload by Serge Modular | Random*Source

"The legendary Serge Resonant EQ now with voltage control over each band - for #eurorack."

SERGE VC RESONANT EQ - A CLASSIC RELOADED

The legendary Serge Resonant EQ is a filterbank with ten bands, designed for electronic sound synthesis and processing, providing formant peaks and valleys similar to those found in acoustic instruments. It is one of the most unique sounding modules with an enormous spectral range. For the VC version, voltage control over each individual band has been added - an attenuverter (CV processor) allows to determine exactly whether the CV applied shall emphasize or decrease each filter band. Each band now also has an individual output.
The CV inputs can also be abused to feed audio signals - e.g. form an external oscillar or one of the individual outputs - into the system.
The eurorack version adds a two-channel mixer with attenuators and a Feedback section which allows to feed back the output signal. A powerful tool for sound processing but also for sound creation!
There are three equalized outputs: the two Comb outputs provide the sums of the two alternate filter bands while the two top outputs are the mix of all filter bands. Please note that there is no sharp separation between the bands, moving any frequency knob will have an influence on both Comb outputs.

4/4/24 (swarm) Gieskes Klok & No Drum + Zerosum Inertia PLXNA2 + OAM Uncertainty + Lexicon PCM 70


video upload by Cfpp0

"Butterflies, bats, 16mm swarm: Gieskes Klok modulates itself and No Drum and Olivia Artz Modular Uncertainty, which modulates No Drum, while Klok gates No Drum."

You cand find additional Gieskes Kok module posts here.

This appears to be the first post to feature Olivia Artz Modular. Details on their modules follow via Perfect Circuit and Noisebug.



"Uncertainty from Olivia Artz Modular is a 2hp coin toss module; it is open source, with new, user-swappable firmware being developed. So, it will continue to grow and offer new functionality!

In the standard firmware, the top input accepts gates, triggers, or any signal between -5V and +5V. Based on whether the input is positive or negative, it uses two different types of logic to produce gates at the corresponding eight outputs. If the input is above +1V, then the module does eight differently-weighted "coin tosses"—one for each output. If the outcome of the toss is "heads," a +5V signal is output for as long as the input stays above 1V. If the input signal is -1V or lower, a slightly different coin toss algorithm is used, where the outputs are paired—if the result of the toss is "heads," the upper output of the pair in question sends out a signal, and if it's "tails," the lower outputs sends out a signal.

Alternate firmwares are available for free, and loading them is as easy as plugging in your module via the rear PCB USB connection, dragging on a file, and you're done. The first new official firmware is a VU meter—with the panel LEDs displaying the current voltage level, and each LED getting a dedicated gate output—somewhat like a multi-window comparator! Olivia Artz's Uncertainty module is a great way to add chance operations to your rack without sacrificing space.

UNCERTAINTY FEATURES

2HP chance module with alternate firmwares available
Default firmware uses two distinct coin toss algorithms to convert incoming bipolar signals into eight streams of outgoing gates

Gimme Some (Kick) Drum by Blue Lantern Modules || Full Walkthrough and Sound Demo


video upload by Robots Are Red

"GSDrum, or Gimme Some Drum, or Gimme Some Kick Drum is a 10 hp drum synthesizer module. It really shines as a kick module, but can do other drum sounds such as toms or something out of the syncussion, or act as a bass synth tracking it 1v/oct. This is not a typical kick oscillator using the 'Twin T' approach, GSDrum uses a v/oct tracking triangle core VCO with an OTA based VCA. There is CV control for the trigger of course, along with v/oct tracking, Linear FM, and VCA accent inputs. The Timbre knob shapes the oscillator starting at a sine wave, to a triangle wave, all the way to an overdriven square wave. Influenced by the Korg ER-1 drum synthesizer. The accent input can simulate midi velocity or drive your sound even more.

via Blue Lantern Reverb

"Part of the 'Gimme Some' series. Gimme Some Drum....

What does this module do?

This module is a complete mini synthesizer that specializes in making analog kick drum sounds.

This product does not use a "Twin T" approach to make it's drum kick sound. This is using an actual 1v/octave

triangle core vco, and ota based vca. The shaper circuit that converts a triangle wave into a sine wave was brought to the front panel. The shaper knob was calibrated to start its shaping at the beginning of a sine wave, and end with an overdriven square wave.

This parameter is called 'Timbre'.

This product can produce a wide variety of ultra generic analog kick drum sounds.

Influenced by the Korg ER-1 drum synthesiszer, but laid out in an analog fashion.

-toggle switches are connected to 'timing' capacitors. You can select decay legnths on the fly.

-Depth Knobs let you precisely dial in how much punch, and loudness you want.

-Accent input lets you simulate 'Midi' velocity but with a positive CV input signal. This makes the Amplifier go louder in volume.

This is basically a CV input for the VCA circuit.

-POP parameter creates a clicky sounding, short audible pulse.

All the internal circuitry was optimized for drum kick. You really can't goof up and not make a percussive sound.

All you need is a triggering signal.

Erbe-Verb B&G | Shared System 'X' | Episode 03 | Back in Black


video upload by Cinematic Laboratory

"Yeah. I made episode 03 before I was able to finish episode 02 so I decided to post them both. There's no need on this channel to manage posts to maximize views, I just want you to be able to find information when you need it and I just LOVE to make content like this. I made a lot of videos about the EV in the past and it's covered in the old Shared System tutorials (link in video). In this video, I am going to try something new.

In this episode, I'll only use Erbe-Verb and DXG in a feedback loop. So no fancy 7U case layout this time, I made this video to find out if it can still be relevant in 2024. Since I am totally biased, you'll need to decide for yourself. Honestly, if you need a regular reverb, maybe a stereo module would serve you better.

Erbe-Verb is going for a limited rerun in black and gold, so this also means it's getting old and possibly moving to retirement. Without speculating too much, it's possible that MakeNoise is working on a successor now they have this amazing new ARM DSP board. But again, I have no idea. What we DO know is, that Erbe-Verb is widely considered as one of the best reverbs in eurorack, even though it's not the best reverb as a reverb. Que? It excels in creative use and abuse. It will never get old and whatever comes next, it will pair well with the EV (it pairs really well with a Mimeophon, StarLab, Sealegs or Desmodus Versio).

Apart from the sound design fun, Erbe-Verb plays a big role in the Shared System signature sound. While it's partly overshadowed by the more recent Mimeophon, the Mime's 'halo' only adds a little space. It's nothing compared to the 'icy sheet metal in deep space' sound from the EV, which can easily double as a classic spring- or plate reverb when 'absorb' and 'tilt' are used to tame the high end. I've never been a fan of the predelay, but it can do amazing things with modulation and gates/triggers.

The Erbe-Verb is 'mono IN' so it needs to be used as a send/return with a stereo voice like XPO or Spectraphon. Here's where a ModDemix comes in handy. You can use CH1 and CH2 to pass on your stereo mix to let's say an X-PAN, and use the Sum out to EV. Then you can patch the EV's stereo out to X-PAN's aux inputs. It's a lot of patching and modules for a verb, but it provides a lot of freedom."

d16group Intros Sigmund 2 High-quality Delay Line


video upload by d16group

"Sigmund is far from just another delay. Four delay lines that can be interconnected in several different ways provide an incredible degree of sound-shaping freedom.

To get more info please visit: https://d16.pl/sigmund2"



"Sigmund is far from just another delay. It provides an incredible degree of soundshaping freedom.

The plug-in consists of four discrete delay units, each with an independent set of parameters that offer you the freedom to shape your sound. There’s an ancient saying, often attributed to Aristotle: The whole is greater than the sum of its parts. With Sigmund, this is especially true as each of the delay lines has complementary modules such as filter and overdrive built in, working independently from the feedback loop. The delay lines themselves can also be combined together in several ways. Sigmund’s user interface has been designed from the ground up to be as intuitive as possible. Everything is presented as if on a silver (or brushed aluminum) platter, cleanly and clearly laid out with instant access to each section and its parameters."

Morphor Plectrum: Demo and tutorial of analog Karplus-Strong module


video upload by CatSynth TV

"We explore the Plectrum module from Belgium-based Morphor, and demonstrate all of its features. The Plectrum is an all-analog implementation of the Karplus-Strong algorithm for plucked string sounds. It uses a BBD 'bucket bridge' delay, and a one-pole low-pass filter to create the algorithm's all-important feedback loop. In this demo, we introduce the algorithm and show how the different knobs and CV sources affect aspects of the sound. We also try out the advanced 'loop extender' feature that allows us to add other modules into the feedback loop of the Karplus-Strong system.

Feedback Modules LFO100 - VCF2600 modulations


video upload by Feedback Modules

"VCF2600 is set in resonance mode and modulated by the LFO100.
All the waveforms and functions are tested one by one."



LFO 100

Complex analogue LFO from a vintage Japanese modular system!

We injected some steroids in this LFO and the results are lot of features.
Not only you can use individually the 8 waveform outputs, but you can use the
alternative two linked outputs for which you can select any of the waveforms.

This alternative output has a VCA so you can fade in the LFO signal in a

defined duration with a potentiometer.

The stairs like waveforms can be changed from 16steps, 8steps, 4steps or mangled.
All of these are seasoned with cv control and waveform reset.



2600 VCF

This filter is based on the classic 2600 from the seventies and uses the LM3900 Norton opamp chip.

It has an audio inputs, two CV ins and an audio out.

You can control audio input level, CV levels, frequency cutoff and resonance.

It has a beautiful sound and it can go from relatively clean to dirty and screamy depending on audio signal level and resonance.

"VCZIIIA SAW is mixed with VCZIIIB SQUARE and with SUB modules.
All three are mixed to the VCF2600. The end of the patch is VCA2600 controlled by the ENV100.
You can hear the bubbly sound of the VCOs, these VCOs made with transistors are not so linear as other VCOs."

VCZIII - FM Modulation

video upload by Feedback Modules

"VCZIII VCOs modulating each other. The shape of the waveform is changed by the 4 slow sine LFOs combos of CMS SLOSINES. You can hear how the FM timbre is affected by the waveform nature."

via https://feedback-modules.myshopify.com

"The VCZIII voltage controlled oscillator modules are our latest creation and are based on the VCOs of one of the most revered analog instruments, the famous British pin matrix synth released in 1969. The VCZIII series VCO is a result of the collaboration of Feedback modules and CMS-LAB and is a modern re-creation of those temperamental, organic and beautiful sounding VCOs from 1969 but with enhancements and adaptations to the Eurorack needs of 21st century.

There are two type of VCOs, VCZIII A based on VCO1 with variable shape SINE & SAW waveforms, VCZIII B based on VCO2 & VCO3 with variable TRIANGLE & PULSE waveforms. Also, each VCO comes in two versions, one with normal fine tune potentiometers and one with precision multiturn potentiometer."

Minimal Jam: Chance Delay & Entropic Doom - random gates, melodic noise, analogue percussion


video upload by AJH Synth Official

"A minimal jam using 2 Chance Delay modules, triggered by a sequencer clock, with the Entropic Doom to create both percussive and melodic noise-based sounds. Also a simple dual-oscillator analogue bass line using 2 Vintage Transistor Core VCOs and the Transistor Ladder Filter. Turn on Subtitles/Captions for an explanation of what's going on.

The Chance Delay generates randomness with its 'Chance' control, which determines the probability of gates occurring. It also uses its Length control to divide the frequency of the incoming clock signal - this is done by forcing the gate lengths to exceed the interval between clock pulses, and not producing further gates until the current gate cycle has finished. It also has a gate-delay function, and all three of these features can be voltage-controlled.

The Entropic Doom is a noise generator with a built-in, voltage-controlled, low-pass filter. This VCF has 2, 3 and 4-pole modes, and is resonant, producing significant self-oscillation in 4-pole mode, whilst also tracking 1V/Oct. This means it can be used melodically, extending it's usefulness beyond just noise washes or percussion. Additionally, it includes an audio input to add other signals into the pre-filter feedback loop, and it can sync it's noise frequency to an external source. To top it off it also features a CMOS ring modulator and XOR VCA, both of which can be used with or without the rest of the module. This thing can go from subtle and pretty timbres to crushing, mangled, distorted chaos.

Two New Modules from Bubblesound Instruments



via Bubblesound Instruments

First up we have the SeM20st.

The SeM20st is a stereo version of the first module bubblesound put out, the SeM20. It has become one of the classic filters in the EurorackWorld.The SeM20st is the most versatile analog stereo filter on the market today.

The inputs on the Left side are all normalized to the Right, so one input can be turned into a stereo signal.There is an Offset for the Left Cutoff, this allows a wider stereo field and is especially useful if the input is coming from a mono source.The CV inputs on the Left can also control the Cutoff and Resonance of the Right side.The Right side CV Cutoff pot is an attenuvertor, when it's at noon it's off, turn clockwise from noon the pot acts like a normal attenuator, gradually adding the CV to the Cutoff.When it's turned counter-clockwise from noon the CV is inverted, acting like an inverted ADSR.This can be used with a single LFO into the Left Cutoff CV to create a sort of ping-pong with the 2 sides, as the Cutoff goes up on one side it goes down on the other.

The Resonance section is exactly the same as in the SeM20, but with the Stereo version the Resonance is controlled by a VCA, allowing for CV control of the Resonance.The Resonance CV will work with either an LFO or an Envelope.

Outputs: Channel has 4 outputs available:
Low, Band, High and Notch Passes.
The Notch Balance pot sweeps from Low Pass to High Pass and can produce some really nice phasing.

width: 10HP

current draw: +45mA -35mA depth: 35MM


Next we have the SpringVerb

The SpringVerb is a classic analog Spring Reverb Driver with a few extras.

The input signal goes into a state variable filter that is capable of self-oscillation.Then the filtered signal goes to the reverb driver, into the tank and back to a Voltage Controlled Crossfader for a CV-able Wet/Dry.The switch under the filter select switch determines what goes into the "Dry" side of the Crossfader. It can either be pre or post filter.

There is a Voltage Controlled Feedback section as well as CV for the Cutoff Frequency and the Resonance of the filter section.

The Feedback does exactly what it says, it feeds the Post Tank signal back into the input section. It can go from very subtile to guitar and amp style feedback.

The Filter is very similiar to the SeM20, so the Resonance is aggressive.The input can be overdriven a little, depending on what the input is. Unlike the SeM20 it doesn’t really clip, but just like the SeM20 when the input is low and the Resonance is high most of what comes out is Sine waves.

Outputs: Filtered, Reverb Only and Mix

Tank:The SpringVerb comes with a medium decay, 3 spring tank and is compatible with many others.

width: 10hp

current draw: +43mA. -30mA

depth - 45MM with RCA cables plugged in

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.

More stuff from me:

30:22 Rungling for chaotic sequencing"



​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.

Hi-Fi stereo FX module
3 delay and 3 reverb effects
Tap and clock synchronization of delay time
Delay time divisions and multiplications in sync mode
10 preset patches
CV control over delay time, feedback, and preset selection

RRP 270 EUR | MAP 329 USD



As its name suggests, the Erica Synths DJ VCF STEREO module provides sound treatment functionality typically found on DJ decks – it is fully open when the cutoff knob is at 12:00. When turned counter-clockwise, lowpass filtering is applied and when turned clockwise, highpass filtering is initiated. Additionally, there is a nice-sounding, adjustable resonance parameter. This provides hands-on control over the sound during performances as well as unconventional timbre modulations that are hard to achieve with conventional state variable filters.

Features
Fully analogue stereo DJ-style VCF
Manual cutoff and resonance control
Two cutoff CV inputs, one with an attenuverter

RRP 180 EUR | MAP 219 USD

Towering Bass Patches | Gyrinx VCF Filter [Demo 5]


video upload by gstormelectro

"Audio + Video by G-Storm Electro c. 2023

Today I'm auditioning a few humongous bass patches featuring the Gyrinx VCF, no effects. Feeding only a couple of 101-VCOs and Pittsburgh DNA Symbiotic Waves. Modulation by 2xADSR and Feedback Modules LFO, Sequenced by Keystep Pro. Headphones or good monitors recommended. Recorded direct to Tascam DR-05, no other mastering just a little normalization.

Gyrinx VCF is a eurorack filter inspired by the vintage Synton Syrinx filter section using Alfa AS3350 chips. Check my Reverb store for Gyrinx-VCF availability" *BLOG* http://gstormelectronica.blogspot.com/

Tech Thursday | Feedback Patching Filter 8


video upload by Joranalogue Audio Design

"It's Tech Thursday! In these concise videos, we bring up some overlooked and advanced features of our modules.

This week, we tackle feedback patching with the very versatile Filter 8. Patching an output to the EFM allows us to craft vastly different waveforms than just the original sine waves that Filter 8 resonates at."
