Tags: Waveshaper module

Notes: Samara is a "Swiss Army Knife" type of module, intended to serve the most common voltage and audio signal processing purposes such as attenuation, offsetting, mixing, inverting, and even basic waveshaping. Samara features four channels, each with two inputs and an attenuator, additional switchable offset generators, four voltage level and polarity indicators, two adders with switchable scale, and a precision four-channel processor that selects minimum and maximum voltage.

Notes: Module A-184-2 is the combination of two functions and planned primarily as an expansion module for VCOs or LFOs (e.g. A-110-1, A-110-2, A-145, A-147-2).

Triangle-to-Sine Waveshaper:

The upper section is a very precise triangle-to-sine converter (thanks to Tim Stinchcombe who recommended this circuit). It can be used to convert any triangle waveform into a (nearly) perfect sine. The converter is much better than the simple diode converter used in the A-110-1, A-111-1, A-145 and A-147-2. Two trimming potentiometers are used to optimize the sine shape. The converter should be assigned to one VCO or LFO because the trimming potentiometers have to be re-adjusted if the input level or DC offset of the input signal changes. If the trimming potentiometers are deliberately mis-adjusted it can be used also as a waveshaper for non-sine waveforms (e.g. sine-shaped at the top of the signal and a peak at the bottom, even voltage controlled by applying an additional voltage to the waveshaping circuit, "circuit-bending" notes will be available).

The waveform converter is DC coupled and can be used also for low frequencies (e.g. LFO triangle waves).

Voltage Controlled Crossfader:

The lower section is a voltage controlled crossfader. It has two inputs A and B. The two signals are mixed together with variable percentage. When the manual control CF is fully CCW only signal A appears at the CF Out socket. When the manual control CF is fully CW only signal B appears at the CF Out socket. In the centre position of the manual control both signal appear with the same level. In addition a control voltage input CV with attenuator is available to enable voltage control of the crossfade.

Two LEDs display the crossfading shares of input A and B.

The crossfader uses two high quality VCAs (SSM2164). Inputs and outputs are DC coupled. Consequently it can be used for audio signals and slowly varying control voltages as well.

The sockets of the upper section (triangle and sine) are normalled to the inputs A and B of the crossfader section. That way the crossfader is used to fade between triangle and sine of the VCO or LFO connected to the waveshaper. If other signals are plugged into the input sockets A and B these signals are used for crossfading.

The main application is to fade between two different waveforms of a VCO or LFO or two different VCF outputs. But the module can be used for any other signals too as the waveshaper and crossfader sections are independent apart from the normalled sockets.

Notes: Dual-channel wavefolding with a lot of creative power. Buchla- and Serge-style circuits combine with a voltage-controlled crossfader, allowing you to shape and sculpt sounds in intriguing ways.

Supplier's Notes:

Bifold is a unique dual channel wavefolder with numerous feedback and routing options along with CV control. Mix, blend and crossfade the two different folder flavours into a rich stew of unique waveforms and harmonic movement. It is the first wavefolder to offer simultaneous, independently controllable serial and parallel folder circuits.

Wavefolding is one of the most powerful ways to produce complex timbres out of a simple sound source or waveform. When done well, the results can be warm, textured, organic and full of musical character. Intellijel studied some of the most revered wavefolding circuits and looked at ways to integrate the positive qualities of these into a design that was full of sweet spots and allowed for a huge amount of experimentation and modulation.

Bifold combines two unique wavefolders with a crossfader; One channel (the P channel) has a sonic characteristic inspired by the Buchla-style Parallel "deadband" folding circuit, while the other channel (the S channel) is more characteristic of a Serge-type Serial folding circuit. There are distinct differences to how they react to specific waveforms, modulation and even their overall frequency response. By linking both folders together with a voltage controlled crossfader we further expand the ability to blend these two different folders together to create new waveforms. But this just scratches the surface of possibilities. Ring modulation, blending, crossfading, complex noise generation, feedback modulation, cascaded folding and so much more are all possible thanks to the strategically placed routing switches, jack normals and attenuators and other control options. This is a module that invites much exploration and discovery and pairs well with almost any kind of modulation and sound source.

Notes: Designed with versatility in mind, the Fold 6 is a six-stage wavefolder with simultaneous series and parallel outputs, dual signal inputs and voltage-controlled folding and overdrive shaping.

Supplier's Notes:
Often considered to be the opposite of filters within a modular system, wavefolders are designed to fold a signal over itself multiple times. This generates additional harmonics, resulting in rich timbres.

While there is a bewildering array of filter types within the synthesiser world, most wavefolders fall within only a few categories. Diode wavefolders in particular come in just two variants: series and parallel circuit topologies. Choosing a specific folder also means being limited to specific sounds and capabilities.

For the first time, Fold 6 puts forward a 6-stage hybrid series/parallel topology, yielding a greater sonic palette than ever in just 4 HP. Having both main (series) and alternate (parallel) outputs means a single module now gives access to just about all wavefolding tones imaginable.

To take things even further, an integrated symmetrical soft clipper limits the output signals to approximately 10 Vpp, keeping the amplitude within typical Eurorack levels and making it easier to create overdriven sounds at high fold ratios. This clipping stage can be driven continuously using the shape parameter, smoothly transforming the folded waveforms into pulse waves for even more harmonic content.

Two signal inputs are included, to mix audio signals or add in a DC voltage for asymmetric folding. The symmetry can also be manually controlled using the dedicated knob. Of course, both fold and shape parameters feature voltage control, to enable continuous timbral modulation.

Moving beyond simple signal processing, Fold 6 also lends itself perfectly for feedback patching, CV folding or frequency multiplication; its modest size belies the sonic capabilities within.

Notes: Versatile and valuable. The amazing Dreadbox Utopia is a CV audio and manipulator. It allows you to control a wide range of different properties inside your Eurorack system. These include four attenuverters, an offset generator, and a four to three mixer. This selection of tools give you the means to take control of your signals and bend them fully to your liking. Helping you put the finishing touches to your synth patch.

Notes: Punch is the ultimate VCA-DECAY module for Eurorack

Specially designed to generate dynamic percussive sounds but also capable of basslines, leads, envelopes and more. The VCA has a built in voltage controlled Decay envelope that can be turned from smooth to more aggressive exponential responses and can be activated with triggers, gates or cv's.

Punch features two modes per channel to play, with a dedicated switch control: "vintage style drum machine mode" and "dynamic cv mode"

Punch is capable of creating AM sounds with control voltage on the "amount"

Each envelope can be inverted via dedicated switches on the front panel.

If you use an inverted envelope alongside the accent input you can create ducking effects like side-chain compression..

INSTALLATION:
* Disconnect your synth from the power source.
* Double check polarity from the ribbon cable, unfortanetly if you damage the module by powering in the wrong direction it will not be covered by the warranty.
* After connecting the module check again you have connected the right way, the red line should be on the -12V.

Notes: The Erica Synths Black Ring-Xfade is an extremely versatile module for sound shaping. It consists of two unconventional ringmodulators/waveshapers, a crossfader that works both for audio and CV and a VCA. Unlike conventional ringmodulator that works only with a signal present on both signal and carrier inputs, the Black Ring-Xfade passes through the signal without alteration, if no carrier is present, but low level signals on the carrier input result in unique waveshaping. Add the crossfader between two ringmodulators (or as a separate unit) topped up with the VCA, and you have an amplitude modulation powerplant in 10HP!

Ring1 CV; Ring2 CV
These are the ringmodulator carrier (CV level) level controls. Unlike conventional ringmodulator, this one passes signal unaltered, if RING CV is turned down. With increasing Ring CV level a slight waveshaping turns into proper ringmodulation.

Xfade
This is a manual Crossfade control. This fades smoothly between signals patched into XFADE IN1 and XFADE IN2. The XFADE CV is added to the knob position.

Coupling
Set the Crossfader mode - AC is optimized for use with the audio signals, DC - for control voltages (but it will work fine with audio, as well).

Ring 1; Ring 2
The green LEDs give visual feedback on signal levels, applied to XFADE IN1 and XFADE IN2 respectively.

Vol CV
Select the VCA CV response. A 0-10V setting is intended for use with the envelope generator, a -5V - +5V setting - for nice tremolos with a LFO.

Xfade IN1; Xfade IN2
These are the Crossfader inputs. They are normalled to the Ringmodulator ouputs, so, if nothing is patched here, you can crossfade between two ringmodulated signals.

Xfade CV
This is the Crossfader CV input. The CV is added to the XFADE knob setting.

VOL CV
This is the VCA CV input. The VCA is post-crossfade - it controls the amplitude of a resulting signal after the crossfader. It will also work with low frequency control voltages applied to the XFADE Ins - nice for designing unconventional modulations.

Ring1 Out; Ring2 Out
These are the ringmodulator outputs.

Xfade Out
This is the Crossfader output and the main output of the module.

Ring2 In; Ring2 CV
These are the second Ringmoduator signal and carrier inputs respectively. These two are normalled to the RING1 inputs, and if no signal is patched here, the duplicate the first Ringmodulator. Interesting trick is to set RING CVs at different levels and crossfade between two ringmodulator signals.

Ring1 IN; Ring1 CV
These are the first Ringmoduator signal and carrier inputs respectively.

Fade L; Fade R
The red LEDs indicate the crossfader position.

Xfade CV LVL
This is a crossfade CV level attenuator. By adjusting it you can control a span of fading between inputs.

Notes: The successor to Dinky's Taiko, Tyso Daiko is a 12-bit dual digital drum voice, with built-in analogue tilt EQ and wavefolder, plus extensive CV control. Intuitive, powerful and versatile.

Supplier's Notes:
The 'Tyso Daiko' is a dual 12-bit digital wavetable drum voice with full voltage control and an analogue EQ output path.

The twin voices are independently triggered and output, but share pitch, envelope and other parameters of a swept wavetable oscillator. One voice is output through a voltage controlled analogue tilt EQ emphasising upper or lower frequencies.

The other voice is output through a digital wavefolder which adds increasing timbral complexity (to noise).

Both voices respond independently to an accent input and the first voice is able to be 'choked' . A surface control allows for fine control of additional transients from a click to a slow attack. Full voltage control including a V/Oct pitch input makes the Daiko an expressive and wide ranging drum module with extremely wide pallet of sounds with lots of modulation possibilities.

The Daiko succeeds the original Dinky with the same spirit but much improved control, new features and new wavetables.

Notes: Arkan

Dual Voltage Polarizer

You may have heard this before: "You can never have enough VCAs". A voltage polarizer (also known as a bipolar VCA or a 4-quadrant multiplier) is often viewed as the VCA better suited for CV. As it can be used as a unipolar VCA and it allows you to invert a signal when it is modulated with a negative voltage. Resulting in interesting movements in your modulations.

What sets Arkan apart from other voltage polarizers is the curvature control, a feature usually only seen in unipolar VCAs. By taking a different approach to the classic voltage polarizer circuitry, Malstrom have devised a unique solution that provides a new way to shape your audio and CV. The non-linearity of the polarizer also makes Arkan really good at reaching silence when presented with a 0V CV signal.

At audio rate, Arkan acts as a ring-modulator with four controls to change timbres.

Boosting adds odd harmonics (symmetrical distortion), while offsetting adds even harmonics (asymmetrical distortion). The modulation curve changes ring modulation sharpness, and modulation strength determines the carrier dominance.

Two identical channels with carefully selected features will make Arkan your go-to modulation control hub. Arkan is especially useful for common utility duties such as mixing, scaling, inverting and offsetting. As well as CV modulation, feedback patching, and waveshaping. All this makes Arkan a very versatile tool that will certainly have a place in your patch!

Features (per channel)

- Input attenuation with inverter switch gives you more precision and range, with voltage inversion and quick silencing.
- Bias input with attenuverter control to offset your input signal or mix/invert another signal.
- CV input with curvature control allows you to shape the polarizer and improve its 0V attenuation.
- CV modulation control to fade in the modulator, allowing you to determine the amount of modulation.
- Voltage gain and polarity led indicators showing you exactly what is happening under the radar.
- Output normalled internally and externally (to other Arkans) to easily mix signals.

Additional features

Optional signal boost (x4 / +12dB) via switch on the PCB to increase voltages when needed.

Notes: Part of Xaoc's Leibniz Binary Subsystem, the updated Drezno ADC/DAC module builds on the original with higher resolution converters, allowing you to use it for pitch quantisation.

Supplier's Notes:
Drezno II is an improved version of the original Drezno module. It is an essential member of the 8-bit Xaoc Devices Leibniz Binary Subsystem. The Leibniz subsystem is a family of modules that operate on 8 binary (two-state, on/off) signals. These signals are arranged as 8 bits of digital data and may represent analogue signals and voltages, or they may be whatever you want them to be (clocks, gates, rhythms, etc.).

Drezno features an ADC (analogue-to-digital-converter) and DAC (digital-to-analogue-converter), allowing it to act as an analog front-end of the system. In other words, Drezno allows one to convert analogue signals and CVs into digital numbers, as well as to obtain analogue signals back from some other digital numbers (or 8 binary signals). Between these two conversions there is a whole universe of digital shenanigans waiting to happen resulting in all kinds of signal transformations and modulations.

Both (ADC and DAC) sections of Drezno can work independently, or they can be linked. Input and output range of analogue signals may be adjusted using Gain and Offset sliders. Individual bit outputs (for the ADC) and inputs (DAC) allow for extensive cross-patching and the creation of complex waveforms and rhythms. A very fast clock (up to 2MHz) at which the conversions are performed may be replaced with any external clock (for each section separately).

Compared to its predecessor, Drezno II uses new converters of much higher resolution which results in much lower noise floor and higher accuracy. The lower bits are much more stable than before. It is easy now to use Drezno for quantizing pitch voltages with accurate results with 128 or 256 semitone steps. Potentiometer ranges are factory calibrated for precise chromatic scale. A new switch on the front panel allows the user to select the calibrated range of 10Vpp or 20Vpp, so that the lowest bit or the second bit correspond to 1 semitone.

Notes: Building on the familiar dual VCO core arrangement of Carrier and Modulator, Mindphaser is a complex oscillator which departs from this bit of ancestral DNA with a modern toolkit focused on searing, phase-modulated leads, percussive basslines and other-worldly effects!

A diverse palette of intermodulation and harmonic experimentation is offered through the Modulation Bus, its unique Waveshaper and the dedicated Thru-zero Phase Modulation Bus. An intuitive interface provides colour-coded visual feedback and responsive indication while performing in dimly-lit environments.

Two precision analogue oscillator cores

Precision, wide-range V/oct ramp cores, each ranging from deep subsonic to supersonic frequencies (ramp cores, and not triangular, deliver the ideal waveforms for analogue phase accumulation in the TZ-PM Bus)
Each core generates fundamental waveshapes which interact and mangle one-another through the complex Modulation Bus and TZ-PM bus
Simultaneous waveform outputs for each base shape
Dedicated button to toggle between RAMP or SAW for each core, inverting the phase of the ramp output
V/oct, linear FM and exponential FM inputs which are all independent of the TZ-PM functionality. The Carrier's FM occurs inside the core itself, separate from the TZ-PM bus.
DC-coupled linear FM

Carrier

The heartbeat of Mindphaser, focused on audio-rate generation. Drives the WAVESHAPER and TZ-PM bus. This core's frequency range spans the audible spectrum.

- An external hard SYNC IN forcibly resets the core, useful for punchy sequences, percussive basslines and drum synthesis -- or to sync to another VCO.

- Coarse and fine controls conveniently span the audible spectrum. Ranges further with external CV.

Modulator

An extremely wide range oscillator, spanning from deep LFO frequencies all the way up to supersonic sound! Four base waveforms and diverse internal routing options form a versatile palette of modulations for the CARRIER to feed on.

- Activating hard SYNC on the Modulator locks its core to the Carrier's heartbeat. The effect can be dramatic. Try this while phase modulating!

- Octave RANGE switch lets you quickly flick up and down between octaves. All the way beyond audio-rate and LFO speed octaves. Perfect for experimenting with different PM sidebands and taming the wide frequency range of the Modulator.

- Manual PW (Pulse Width) control and dedicated CV input for PWM.

Waveshaper

This isn't a classic waveshaper! Developed anew from the ground up, this waveshaper is focused on deep harmonic experimentation and audio obliteration. Each waveshaper parameter is capable of being "turned up to 11".

FOLD up to 5 octaves above the fundamental Carrier frequency. A ceiling forms at maximum, imparting additional harmonics.

FEEDBACK the waveshaped and phase-modulated audio through a signal path internal to the waveshaper.

AMPLITUDE modulation spans thru-zero, allowing for full-range ring modulation effects with bipolar CV or audio signals.

CLIP the final stage of amplitude with the switch to introduce a last stage of harmonics before the complex signal exits through the final OUT.

Switchable inverting attenuators on each CV input, for quickly inverting the behaviour of your modulation. The indicator illuminates red to tell you the attenuator has been inverted.

Two distinct waveshaping modes

A press of the shape switch toggles Mindphaser between RAMPOID (green) and TRIANGULAR (yellow) waveshaping modes.

These modes have a remarkable effect on the behaviour of wavefolding and overall character of the final complex OUT, in addition to TZ-PM Bus character.

RAMPOID mode folds more asymmetrically, with raucous, buzzing harmonic artefacts as you sweep and introduce TZ-PM

TRIANGULAR mode folds more symmetric, splitting the complex sine wave at its peak centre of the waveform. TZ-PM character is less raucous, and more smooth.

TZ-PM Bus

Thru-zero phase modulation in the ANALOGUE realm! Unlike its digital counterpart, analogue TZ-PM has its own character we've come to expect from analogue circuitry!

A dedicated, voltage-controlled phase modulation bus completely separate from the Mod Bus
Modulator's SINE wave normalled to the PM SOURCE input
SOURCE input allows you to modulate phase with any signal you patch in
Dedicated voltage-controlled INDEX (amount)
Manual phase lets you zero in (or not!) on the base phase before introducing modulation
Independent of the Linear FM circuitry in the Carrier core

Mod Bus

The internal modulation powerhouse, normally fed by the Modulator core, but external signals are patchable as well.

Select from the PULSE, RAMP/SAW or SINE output of the MODULATOR, or inject your own SOURCE to the bus.

Voltage-controlled INDEX behaves like a macro control when combined with various amounts and polarities dialled in at each CV destination.

Internal sends include the Carrier's classic Linear FM, Amplitude, Feedback and TZ-PM Index, with variable amounts and polarities!

Modulator waveforms internally feeding the Mod Bus behave unipolarly, for predictable modulation of every Mod Bus destination, without external patching. By patching in one of the Modulator's bipolar waveform outputs manually (or any external signal), you can override this behaviour.

Notes: The VCZIII voltage controlled oscillator modules are Feedback's latest creation and are based on the VCOs of one of the most revered analogue 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.

Notes: The Flexshaper is a highly versatile module when it comes to modify evolving voltages in other directions and levels.

Five settings allow you to fold/expand/clip/compress/invert partially or completely any CV or audio signal.

The module can act as an envelope-shaping tool, frequency multiplier, waveshaper, clipper, distortion, limiter, curve changer, and more.

Five CV inputs offer limitless control over the placement of the voltage points for dynamic signal sculpting.

Birth of the product

The idea of the Flexshaper comes from a feature in the Oberheimr Matrix synthesizers called Tracking Generator.

This signal processor was part of the modulation matrix and meant to be virtually inserted between modulation sources and destinations in order to change the shape of the controlling signal.

The Flexshaper applies the same concept using the same 5 shaping points. However, it goes beyond Oberheim's implementation on two main aspects:

It goes fast enough to process signals at full audio rate
The 5 points are dynamically adjustable (CV) in real-time
Besides, the Flexshaper can process adequately bipolar and unipolar Eurorack signals, even changing them one another.

Notes: Welcome to the Rosci soundscape. Rosci is a digital VCO that generates random waveforms to create unique, rich, and full sounds. You are able to control how complex the sound is-add harmonics and have a completely unique shape generate using the generate button/trigger. BUT, it can also be tuned to output basic waveforms (sine, square, sawtooth) if you so desire.

Tunable parameters breakdown:

COMPLEXITY: Essentially a generation of unique timbre.
ROUNDNESS: Set the basic shape of your waveform. Go from from sharp to soft sound, similar to filtering.
HARMONICS: Add up to 6 harmonies to your sound. The choir's here.
FORMANTS: Accentuate certain overtones in your sound (like a voice singing "ooo", "ahh", "eee").
DETUNE: Add a classic 'detune' with a changing phase wave for extra wide sound.

How does it work?

It is a pipeline of algorithms, which generates and modifies a waveform starting from top to bottom. Rosci works on a principle of key points: the generate button generates key point location and amplitudes to be passed down the pipeline.

Tunable parameters:

Beginning with complexity, you set the number of key points (even numbers only to create a waveform). Lowest complexity sets two points, and highest complexity sets up to 20 points. The number of key points will vary with each waveform generated. From there, the roundness sets the type of interpolation of the key points, from square to sine. Adjusting the harmonics creates copies of the waveform and adds them to the original waveform at double, triple, ... up to 6x the base frequency. Formants maintains the frequency of the wave, but squishes it so there is 'empty space' in between (this is also called pulsar synthesis). Finally, detune copies the waveform and 'detunes it' by increasing the frequency ever so slightly. And there you have it: a unique Rosci soundscape :)
