ADDAC System ADDAC102 VC FM Radio Module (black faceplate)
Cat: 773955 Rel: 08 Sep 20
 
FM radio module
Notes: This is Version 2 of this module, updated in order to be skiff friendly.

With the ADDAC102 FM Radio you'll be able to tune-in FM radio. Besides the ability of station broadcasts as sound generators for your synthesis, you can also have a lot of fun with the fact that its a great noise generator- the static picks up all kinds of great electromagnetic interference.

It provides controls like tune, volume and seek (all of them controllable through CV input) and there's two outputs for stereo sound.

ADDAC System ADDAC104 VC T-Networks Module (black faceplate)
Cat: 776116 Rel: 08 Sep 20
 
4 voice module
Notes: Following the ADDAC103 T-Networks, this new module is also inspired by Twin T-Networks circuits used in many lengendary drum machines. A simple 4 voice module with frequency controls for each of the voices. This new module also features CV inputs with attenuverters for each voice Frequency. Due to the specificities of the circuit, and to keep the module at a low price, these inputs are not callibrated to 1v/octave.

At each voice input there's a gate to trigger converter so any input source is possible.
Audio inputs can also be used as an input, in this case and due to the nature of the gate to trigger converter, each voice can be used as very destructive filters.

The top 2 channels feature a higher frequency range, the bottom 2 channels feature a lower frequency range.

ADDAC System ADDAC111 Ultra .WAV Player Module (red faceplate)
Cat: 776121 Rel: 08 Sep 20
 
.wav player module
Notes: The ADDAC111 ULTRA .WAV PLAYER is the long awaited upgrade to the praised ADDAC101 .WAV PLAYER.

While keeping all functions of the original, there's more dedicated controls as well as a few new functions.

For this version, Micro SD Cards were used- this decision was made in order to help the hardware construction and make it only 3cm deep.

An Expansion module, ADDAC111B, was also created to allow users to recall the first 8 files through dedicated trigger signals. This allows sequencing of files.

The Loop Size, Start Point and Sample Rate defines how the loop is played.

Loop Settings defines if sample is looping or playing only once.

File Access if it advances to the next or previous file.

The VCA section controls the overall volume of the module.

And finally the Envelope Follower generates a CV voltage related to the amplitude of the audio signal pre-VCA.

ADDAC System ADDAC111B Ultra .WAV Player Expansion Module (red faceplate)
Cat: 776125 Rel: 08 Sep 20
 
Expansion module
Notes: The ADDAC111B EXPANSION allows the user to access the first 8 files (a to h) through a trigger.

Files do not play simultaneously, if several triggers happen at the same time top priority goes from top to bottom- meaning that if B E and F triggers are received at once the file that will be played is file B.

The expansion module should be plugged to the back of the Ultra .Wav Player module. There's no connection to the bus boards.

ADDAC System ADDAC112 VC Looper & Granular Sampling Module
Cat: 811085 Rel: 30 Apr 21
 
Expander/digital/sampling eurorack module
Notes: There's a long history behind the granular concept and many reinterpretations of it's core principles, this is ADDAC's take on it.

In a loose description, digital Granular refer to pieces of sound files being played at the same time with slight or completelly diferent parameters originating what is commonly refered to as granular clouds. Normally, there's a buffer size from which the granular engine snips it's pieces from and plays them according to the parameters set. This buffer size is normally small in size where grains are so small that can reach the hearing spectrum and be heard as a sort of ever changing complex wavetable, this is the principle behind granular synthesis.

In our vision we added the possibility of long buffer sizes up to 5 minutes, allowing "softer" aproaches to the granular principle using it as an effect that can generate from "accidental" effects like slight "stutters" to extreme processing and transformation of any incoming audio signal.

This module is conceptually deep but easy to grasp and operate as all controls are in it's dedicated panel, all jack inputs and outputs have it's own separate panel to allow no compromise when playing its controls.

There are three main sections in this module:
Looper Engine: The Looper is where all the Real-Time recording happens. The audio input feeds the recording buffer, multiple controls allow to record and play loops into a list so that any sample in the list can be accessed at ay time and more acting as a standard looper
Granular Engine: The Granular acts upon the buffer of whatever LOOP is selected.
Output Mix The output mix allow individual control for the Dry Input, Looper Volume and Grains Volume.
Besides these main sections there's also a simple strip down MENU mainly used to LOAD and SAVE Banks, no Menu diving guaranteed.

ADDAC System ADDAC209 VC Time Compensated Glide Module (red faceplate)
Cat: 776185 Rel: 08 Sep 20
 
Glide/slew circuit module
Notes: This is our take on a glide/slew circuit. It introduces a time compensation for the glide/slew rate so that any interval have the same glide time.

Normal glides have a fixed speed, they take X time to go up a semitone and X*12 to go up an octave. A compensation circuit was added to detect and dynamically change the speed according to the distance needed to be made, so that in the end it'll take the same time to reach the final destination no matter if the interval is 1 semitone or 3 octaves. This compensation feature (dry/wet) can controlled by the front panel knob or by CV.

ADDAC System ADDAC215 Dual S&H+ Module (black faceplate)
Cat: 776254 Rel: 08 Sep 20
 
Dual sample & holds module
Notes: This new module should not be judged by it's size, at 6hp it's packed with features.

At its core it features a noise source and two precision Sample & Holds with 0.01% of maximum deviation from the Input which allows for quantized signals to be sent through without any noticeable detuning or the typical voltage drops over time.

The Sample & Hold sections can also be used as a Track & Hold meaning it holds the incoming input while the Trigger input is ON and lets the input flow to the output when the Trigger input is OFF.
Each section also features it's own slew processor with a single control over attack and decay and an ON/OFF switch.

The noise signal is normalled to both sections inputs, meaning that without a jack plugged into the Input the sample and hold function will act upon the incoming noise signal generating random CV values.

The [Trigger A Alternate] switch allows to Link both sections so that any trigger input in Trigger A will alternate between triggering the A and B section.

Besides each section outputs there's also 4 extra outputs: Noise, Difference, Average and Sum. The Noise output is coming from the noise source, the Difference output is the subtraction of section A minus section B, the Average output is the sum of both A plus B and then divided by 2 and finally the Sum output is the sum of both A plus B sections.

ADDAC System ADDAC216 Sum & Difference Module (black faceplate)
Cat: 776260 Rel: 08 Sep 20
 
Sum & difference module
Notes: There are two equal sections in this module labeled A and B.

This module is a peculiar type of mixer that instead of just summing two input signals (X & Y) it also allows the possibility to subtract the two signals.
It works both for audio and CV signals and hence the possibility to get the diference of two CVs or cancel the phase of two audio signals. The resulting signal, of sum or subtraction, is then routed through a switchable (on/off) full rectification circuit labeled: Absolute. After this the gain of the mixed signal goes through another attenuverter labeled: Amplitude to control the resulting signal gain which, being an attenuverter, also allows the possibility to invert the incoming signal. After the Amplitude comes an AC/DC coupling switch followed by an bipolar Offset knob.

Besides the normal output, there's also an inverted output for each of the A & B sections.

The outputs of section A & B are also summed and sent to the Average Output.

Using a single input, just the X or Y input, the module can also be used as a simple dual Attenuverter & Offset CV processor with full rectification and AC coupling options.

Average mix output of both sections.

ADDAC System ADDAC217 Quad Gate to Trigger Module (black faceplate)
Cat: 776261 Rel: 08 Sep 20
 
Gate to trigger module
Notes: Following ADDAC System's T-Networks series, the importance of having the right input signal for firing drum modules or envelopes was realised. Gates and Triggers are often looked at as similar signals but at times it really makes a difference and results will change drastically depending if a Gate or a Trigger is fed to the input of such modules.

This led to the simple yet effective Gate to Trigger.
A four channel converter with bypass switch for each channel.

Any input Gate will be limited to a 1ms Trigger.

ADDAC System ADDAC405 VC Relabi Generator Module
Cat: 797099 Rel: 17 Dec 20
 
Clock generator/clock modulator/LFO/quad/comparator synth module
Notes: Complex gate and CV generator designed as a trigger source and modulation tool. Based around four sine wave LFOs that mix together and interact to create ever-changing patterns.

Supplier's Notes:
In 2009 John Berndt coined and defined the term Relabi in his essay "Relabi": Patterns of Self-Erasing Pulse, these are his own words: "Relabi, Def.: The experience of a palpably coordinated plurality of events that appears to be cyclical but simultaneously suspends identification of a uniform pattern, preventing a resolved sense of pulse. Relabi therefore seems equally pulsed and unpulsed at the same time. It is an experiential gestalt, a quality of experience, greater than the sum of its parts (it forms a sustained unity in experience, albeit of a new kind)."

He also makes the question: "Why would anyone want this Relabi experience? I maintain that much of what is exciting in musical forms involves an interplay between the setting up and denying of pulse expectations."

Inspired by this idea, ADDAC System developed this module that is both a gate/trigger and cv generator that can be freely used to trigger events or act as a complex modulation source. Four Sine LFOs are internally generated, each has controls for gain, frequency and mute(off). These 4 LFOs are then mixed together to generate what Berndt named the "Relabi Wave" this "wave" becomes a complex bipolar CV source. This i5v bipolar "wave" can be monitored on the 2 dedicated leds and is also available at its own Output.

Make sure to check the User's Guide for indepth description, working behaviour and diagrams.

ADDAC System ADDAC503 Marble Physics Module (red faceplate)
Cat: 776332 Rel: 08 Sep 20
 
Marble physics module
Notes: Newtonian physics on a modular synth! The ADDAC503 Marble Physics is a CV generator based on the mechanics behavior of a marble on a tray.

Through this realtime physics simulator you'll be able to control several parameters that will affect the behavior of a model of a spherical object against a plane. You can tilt the plane or bump the marble with a certain strength, which will cause it to roll and bounce on elastic walls.

The model will output the object's XY position or velocity and you can control other physical parameters, like the walls' elasticity or the strength of a bump. When the marble hits walls the bounce output triggers and you can additionally lock the X axis for a one dimension simulation. Finally you can also set the overall speed of the simulation.

By controlling all of these properties you be able simulate several scenarios where the marble falls, gets gently pulled by gravity, orbits indefinitely or bounces on walls like a pinball. Truly engaging physics simulations!

ADDAC System ADDAC603 VC Triple Bandpass Filter Module (black faceplate)
Cat: 776351 Rel: 08 Sep 20
 
Triple bandpass filter module
Notes: The ADDAC603 VC Triple Bandpass Filter provides three channels of bandpass filters, fantastic for sculpting complex sounds. Each of the channels feature a gain/distortion control with switch to select between x3 or x100 gain, which can cause the input signals to distort, adding another layer of harmonic interest.

The inputs are cascaded together to allow for one source to be filtered three different ways - or each filter can be used independently. The three filters also feature controls for frequency, which sets the cutoff point; width, which sets the width of the band that is being filtered; feedback, which at high settings causes the filter to self-oscillate, and level control, which sets the amplitude of the output. Frequency, bandwidth, and output level each have CV inputs with attenuverters.

A switch sets whether the filter is 24 dB or 12dB per octave. There are individual outputs with phase switch, plus a mix output and dry/wet output with adjustable control for mix balance. This module provides a wide variety of filtering options to add complex tonal shaping to your rack.

ADDAC System ADDAC604 Dual Filter Module (black faceplate)
Cat: 776353 Rel: 08 Sep 20
 
Dual filter module
Notes: Really nice stuff here. The filter circuit from ADDAC's 4 Voice Cluster module gets reimagined as a multi-mode stereo or dual mono filter module. A lot of filter action in just 6hp.

Supplier's Notes:

While developing the ADDAC105 4 Voice Cluster module, a new multimode filter to place after the summing mix stage- and the results were so postitive that it was released as a dedicated filter.

To make it more interesting, the circuitry was duplicated, to be able to use it in a stereo signal path.

To make it more versatile, a switch was added to set the working mode from Stereo to Dual Mono where both filters can be used independently.

In Stereo Mode the Left Cutoff is used to control the Right Cutoff.
In this case the Right Cutoff Knob and CV Input are simply bypassed and will have no impact on the Right Channel operation.
This allows immediate sync of both filter frequencies when the Stereo position is engaged.
Optionally there's a jumper in it's back that, when placed, connects the Right Controls back to the Right CV control allowing the possibility to control the offset of the Right Channel Cutoff.

Resonance is independent on both Modes and still has to be set manually to match both channels.

Both the Audio and CV inputs are normalled from the Left into the Right channels.
As standard plugging any input to the Right channels removes this connection.

ADDAC System ADDAC605 VC Spectral Tilt Module (black faceplate)
Cat: 791268 Rel: 08 Oct 20
 
VC spectral tilt module
Notes: Two-channel spectral tilt filter with simple single-knob control and CV input. Adjust the frequency balance by turning the knob to emphasise highs or lows. Simple but effective way to add movement or stereo width.

Supplier's Notes:
The TILT EQ concept was first introduced in the 1970's by Quad Ltd, featured on the company's model 34 preamplifier.

The tilt control tilts the frequency spectrum of the audio signal by simultaneously boosting the treble and cutting the bass frequencies, or vice versa, making it a simple to use but powerful EQ.

As stated by Quad Ltd, it was designed to produce a very gradual change in balance across the musical spectrum without changing the overall subjective level.

This gradual fall from Bass to Treble, or vice versa, means there's no sudden change and hence no 'coloration' added to the sound, the sound will remain entirelly natural but with a slight added bottom or high end. In practice, it rotates most of the audio-range frequency response around a 1Khz axis, so as to change the overall balance of the sound from warm to cool without affecting either the apparent volume or the "color" of the sound.

Here this idea is introducedinto the modular world in a stereo configuration.

CV input with attenuverter was added for the Tilt control as well as a Spectral Motion switch that allows stereo spectral matching or inverted spectrum use of the Tilt control: Left=Right matches both channels direction, i.e. when left channel is tilted to the low end the right channel will also be tilted to the low end

Left Right inverts the Right channel spectrum, i.e. when left channel is tilted to the low end the right channel will be inverselly tilted to the high end, or vice-versa.

This possibility is extremmelly interesting when applied as a stereo effect, in other words a spectral EQ panner. This module will also be available as a full DIY kit.

ADDAC System ADDAC611 Gotharman's VC Tube Filter Module (black faceplate)
Cat: 776355 Rel: 08 Sep 20
 
Tube filter module
Notes: This module was developed upon the Tubaz Filter which was released in 2014 by Gotharman but is currently no longer in production. We loved the original module so much that we officially licensed it's circuit and expanded it to feature several new functionalities.

Here's a paragraph from Gotharman regarding the original design:
"I designed it with the purpose of adding crunch, edge and distortion to my eurorack system. It is not an ideal bandpass filter, that cuts off all frequencies above and below the center frequency.
Because of its high drive, there are, in most cases, some bleedthrough of the harmonics, that should have been cut off. You might consider calling it a "Band Add" filter. The main purpose of it, was to add edge, not to be a perfect bandpass filter."

While everything he mentions is still true we believe he was being modest, It's a dirty, gritty, growling and whining monster which promises you some of the most peculiar filter sounds you'll ever hear.
However do not classify it as a "weird" distortion unit just yet because besides this hairy character it can be easily tamed (using lower volume levels) and then, with some care and intention from the user, it will transforrm itself showing it's feline purrrrr and cuddle sweet and caring, or like any good mut, showing up at night all happy, wet and dirty from a full dog's day and will lay down at your feet while wiggling it's tail howling as yawning just happy to be back home.

As such, standard volume principles do not quite apply to these units, the Audio Levels will go up to x2 amplification, Drive will go up to x11 and master outs go up to x2. The combination of these will cover all diferent qualities it can present. Overall sound can be distorted pre-Tube (raising input levels), in Tube (raising drive) or post-Tube (raising Out levels).
Higher Inputs and Drive will always be gritty, lower Inputs and Drive volumes together with higher Output levels will make the overall behaviour more mellow and closer to what a typical filter would behave like.

No standard expectations should be considered when acquiring these units, all of the tubes were built in the 70's and were bought from various sources, we always kept the premise that no tube was a bad tube (unless not really workinng) so due to each specific characteristics no module will sound exactly the same, making each unit particularly unique. This uniqueness will be particularly evident on their resonance/self-oscilating timbre as well as in their own microphonic qualities.

Regarding power and current draw, the module is designed using a low power tube, so it won't starve your eurorack power supply.

ADDAC System ADDAC702 Dual VC Filter Module (black faceplate)
Cat: 776359 Rel: 08 Sep 20
 
VC filter module
Notes: Here's our first Voltage-Controlled Variable Filter, inspired by the original MS-20 filter.

This module features:

Two independent filters, a High-Pass and a Low-Pass with dedicated audio inputs and outputs.

Besides individual outputs the HP and LP are also sent to a voltage-controlled Mix between the HP and LP filters.

Both Cutoff and Resonance are voltage-controlled with dedicated cv attenuator pots.

Switch for selecting between normal cutoff behaviour and an adjustable Smooth circuit to simulate a vactrol behaviour for cutoff control.

Switch for setting filters Filters in Parallel (independent) or Series (HP > LP).

Inspired by the Oscar synthesizer we added a Coupling switch to tie the HP Cutoff control to the LP Cutoff control, in this case the LP cutoff controls act as an offset from HP setting.

Three position switch selects different resonance clipping paths: diodes / no clipping / leds.

Both filters features a post Distortion/Fuzz circuit that adds extra harmonics adds an even deeper growl or extra gritiness to it.

All audio outputs (HP, Mix, LP) feature a switch for choosing phase output, allowing additive or subtractive mixes.

Three Leds monitor the amplitude of the three outputs (HP, Mix, LP).

ADDAC System ADDAC800X High-End Outputs Module (red faceplate)
Cat: 776392 Rel: 08 Sep 20
 
Outputs module
Notes: Inspired by the legacy designs of premium vintage gear, the ADDAC800X behaves like a high-quality DI box and is all about keeping the sound coming from your Modular free from any undesired noisy interferences, making sure that what you're getting from your outputs is what your Modular is actually producing. It provides galvanic electrical isolation between the Modular system and external sources preventing impedance mismatch and ground loop induced hum. ADDAC's 800X circuit is designed around a unity 1:1 type nickel core Hammond Audio Transformer from the 140UEX series (equivalent to Jensen audio transformers).

Operating in the 20 Hz to 20 KHz range and providing exceptional shielding from external sources, this impedance matching transformer provides the 800X with two fully balanced high-end outputs (via XLR connectors).

Applying a transformer balanced output isolation has lots of advantages over other less expensive ways for dealing with ground loop issues. This method provides the chance to set a very simple and clean circuit in which the signal transfer process develops smoothly and humming free. The transformer is a device that performs both signal balancing and high-to-low (or vice-versa) impedance conversion, while rejecting straggled DC voltage and Radio Frequency Interference from signal passing through a magnetic bridge. In a transformer, two (or more) coils (called windings) of insulated wire wound around a magnetic metal core allow for its input(s) and output(s) not to be physically connected together. When an AC signal passes through the input winding (the primary), a perfectly related AC signal appears on the output winding (the secondary). This way, by the fact that signal flows via inductive coupling between the two windings of the transformer, the ADDAC 800X presents a most accurate electrical isolation between its input and output. A same number of windings on each coil guarantees that there's no gain loss when audio signal passes from the primary to the secondary windings. Furthermore, since these two windings are insulated from each other, the transformer will electrically isolate the 800X from any other device, preventing hum problems coming from an outsider ground.

LEFT IN will output sound to both channels.
Through RIGHT IN, signal will only find its way on OUT 2 (if the LEFT/RIGHT toggle is lifted up, RIGHT IN will be ignored and LEFT IN will be present in both OUTs). With both INs connected you'll have two separate outputs (LEFT IN -> OUT 1 & RIGHT IN -> OUT2). However, lifting up the LEFT/RIGHT toggle you'll also find RIGHT IN ignored and LEFT IN will fed both OUTs.

Each TRANSFORMER ISOLATED OUTPUT section has its signal overload warning led and two dedicated toggle switches: one that works as a simple amplifier / attenuator pad to +6dB / -10dB respectively, and a LIFT/FLOAT/GND toggle. This last one is a 3-way selector that lets you choose between lift, ground or floating ground (toggle's middle position) to be taken as reference for the ground point. In the LIFT position the module circuit will be lifted to ground through a 100R resistor and a 10nF capacitor and pin 1 of the XLR connection will act as the ground point. Choosing GROUND will put ground to be shared between inputs and outputs. Floating ground will leave ins and outs grounds completely apart from each other. Any of these three positions may be the best form of avoiding ground loops or any other undesired interference occurring between your modular and the sound system you're plugging it into. Try out which one of this options will work the best in a given situation.

An HEADPHONES AMPLIFIER (with VOLUME knob) connection is available for quietly working with your modular or pre-listen your sounds before making them public matter in a live situation. This section features an OPA2134 High-Performance Audio Operational Amplifier. This device presents the ideal characteristics for use with an headphones set, like ultra-low distortion and low-noise fully specified for audio applications, in combination with high-output drive capability and excellent DC performance that altogether allow for high-dynamic headroom and really superior sound quality.

ADDAC System ADDAC803 Quadraphonic Spatializer Module (red faceplate)
Cat: 776406 Rel: 08 Sep 20
 
Quadophonic spatializer module
Notes: This is ADDAC System's Quadraphonic output module.

Using the VBAP (Vector-Base Amplitude Panning) principle, it allows to position a mono signal over a quadraphonic speaker array for sound spatialization. The VBAP algorithm can be controlled by Cartesian or Polar methods

Sound path is fully analogue featuring 4 high quality VCA's.

Featuring both 1/4 inch and 3.5mm jacks for adapter free connections.

Four 16 bit CV outputs mirror the signal sent to the VCA's control, when connected to 4 external VCA's these can be used for Polar Mixing of 4 diferent sound sources.

The 2 Filter CV outputs react according to the distance from the center point. The + output increases as the sound gets further away from the center of the room allowing to sync a Low Pass Filter to the input sound so that as it moves away from the center the High Frequencies get attenuated further increasing the spatialization experience. Another good practice would be to sync a reverb dry/wet signal as well so that the sounds gets more difused as it moves away from the center into the horizon.

Both the filter and the reverb should be plugged between the sound source and the 803, in order for the incoming sound to be processed before being routed to the 4 outputs.

The X and Y CV outputs mirror the cartesian sound position between 0 and +5v.
