Notes: Introducing ADDAC's Cable Tester, a desktop utility that provides a reliable means to test the integrity of both mono jacks and ribbon cables, ensuring that every connection is secure and electrically sound.

Individual Wire Testing - Featuring the ability to test each wire within the ribbon cables independently with dedicated LEDs for every wire, providing a clear visual indication of the status of each connection, wires are also tested against their neighbouring wires to detect shorts.

Busboard monitor

The busboard monitor LEDs allows the user to check the state of the busboard power lines as well as the special CV/Gate functions. If the busboard has no +5v supply the led will be off likewise for the CV/Gate functions if not in use.

This is a desktop device, ADDAC provide a long power cable so that it can still be plugged into your rack.

As a safety precaution only power this board when you need to test a cable. Leaving it ON at all times can lead to unintended problematic misuses which, in a worst case scenario, can shorten your Eurorack PSU,

! WARNING !
DO NOT POWER MODULES FROM THE TEST SOCKETS!!

Compatible with all ADDAC System ribbon cables (power, expansions and interconnectivity: 112, 213, 807).

Also compatible with any standard Eurorack power ribbon cable (2x5 to 2x8 or 2x8 to 2x8).

! WARNING !
NOT ALL MANUFACTURERS FOLLOW THESE STANDARDS!
ALLWAYS NOTICE THE ORIENTATION OF THE HEADERS IF YOUR CABLE DO NOT FOLLOW THE STANDARD THEN MOST PROBABLY IS NOT COMPATIBLE.

Notes: ADDAC813 is a straight forward stereo mixer. Featuring 5 stereo channels, 4 of them with attenuators, a mono send/return path for parallel processing plus stereo and mono outputs

Four channels with stereo input and gain knob. Fifth channel with stereo input without gain knob, which are the prefered inputs to cascade several ADDAC813s when more channels are needed. Master Output controls the level of the Inputs mix. Two LEDs monitor the inputs mix.

Mono Send / Return return path allows for easy integration of mono effects in a stereo chain. Plug your favorite module through it (filter, bbd delay, spring reverb...) or any mono pedal.

The Return Gain works in parallel with the Master Output, just like regular wet / dry controls.

The send output can be configured to be line or synth level via a jumper in the back.

Stereo output sums the Inputs Mix with the Return signal.

The Mono output is the sum of Left and Right outputs

Effect Pedals

Using the send output at Line level, the user can connect the send output directly into mono effect pedals and have the pedals output connected directly into the return input without the need of an attenuator/amplifier module.

Notes: ADDAC309 CV to Expression allows a simple and straight forward connection between modular and effect pedals that features expression pedal TRS inputs.

Instead of using an expression pedal into the effects pedal the user can use this module in between a CV source and the Effects pedal to be controlled.

This is a great way to control the available parameters on the effects pedals straight from a CV source.

ADDAC309 features 2 channels each with a CV Input with attenuator and a 1/4" jack output.

This is a passive module, the power needed for operation is taken from the pedal power instead of the modular frame, this allows for perfect matching of the pedal's operating voltage which can range from 3.3v to 9v.

Notes: Following ADDAC's ADDC503 Marble Physics here is a new simulation of a physical system. This time, imagine a small area in the middle of the ocean, in this area we place 4 equally spaced buoys anchored to the bottom in such a system that we can control the spacing between the buoys. Imagine we can control the elements and agitate the waters at will which in turn will make the buoys move up and down as the water surface moves.

Finally imagine the buoys would wirelessly transmit their absolute height directly to your module outputs where they would be mapped to a voltage signal.

ADDAC use a Gerstner Wave as the motor behind the two-dimensional wave generation. In fluid dynamics a Gerstner Wave is described as "a progressive wave of permanent form on the surface of an incompressible fluid of infinite depth". Gerstner waves are often used in computer graphics to simulate any type of water surface, if you've seen any animation film or computer game with water surfaces in it most probably it features a Gerstner wave generating it.

Notes: ADDAC System's smallest buffered multiples allow you to connect one source to its input and have it distributed through all of the 3 adjacent outputs. You get two sets of four connectors. and it can do both audio and CV!

Notes: This small utility is the pedal's lover best friend, it allows 2 diferent chains of pedals to be independently connected to your synth.

The Send channels attenuate the synth level to instrument level.

The Return channels amplify the signal from instrument to synth level.

Notes: Most musicians use their feet as an extension of their playing, either pushing piano pedals, sustain pedals, guitar pedals.

However, feet have been underrated while using modulars. In the past ADDAC released a series of modules using sustain and expression pedals for triggering or controlling signals to help breaking the ice. While these are small and still useful for simple uses, ADDAC wanted to create something more specific this time.

This new solution features 5 footswitches and 5 inputs for external expression pedals with independent controls for each.

The aim was to save HP rack space and so created an external floor pedal with all the footswitches and controls, keeping the module HP to the minimum possible featuring only the 10 outputs and the connector to the external floor pedal.

There are many expression pedals in the market and although the most common one is the TRS pedal there are 2 other standards: RTS and TS.

All five ADDAC311 inputs expect TRS pedals, if you're looking into buying one choose a TRS pedal.

If you already have other pedals channel 4 features jumpers that can be switched in order to be used with a RTS pedal.

Channel 5 features a jumper that can be switched in order to be used with a TS pedal.

External expression pedals are required for their outputs to work.

External expression pedals are not included

Notes: ADDAC710 is a dual channel Isolated 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 710 circuit is designed around a unity 1:1 type Low-cost Audio Transformer operating in the 20 Hz to 20 KHz range, this impedance matching transformer provides two fully balanced outputs (via XLR connectors). ADDAC710 is a low-cost alternative to the ADDAC800X High-End Outputs module, we redesigned the original circuit using a smaller low-cost transformer that also reduced its depth allowing it to fit shallow Eurorack cases.

There are two independent channels on the module with:

Audio Input

LIFT/FLOAT/GND toggle switch
Signal overload warning led
XLR Output

The LIFT/FLOAT/GND 3-way switch lets you choose between lift, ground or floating ground.
In the LIFT position (left) the module circuit will be "lifted" to ground through a 100R resistor and a 10nF capacitor.
In the FLOAT position (middle) Ground will not be shared leaving ins and outs grounds completely apart from each other fully isolating both signals. in the GND position (right) Ground will be shared between inputs and outputs, here no isolation is used.
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 these options will work best in any given situation.

The importance of using Audio Transformers
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, this module 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 ADDAC710 from any other device, preventing hum problems coming from an outsider ground. Being a low-cost transformer the frequency response curve is not as linear as our 800X, still the -0.2dB attenuation at 50Hz feels negligible.

Phantom Power

+48V Phantom Power is NOT needed for the module to operate.
In any case having Phantom Power ON won't influence the module operation.

Notes: ADDAC809 is a dynamic CV operated I/O router that allows one source (Audio or CV) to be routed through 2 different chains (of one or more modules) before being sent to an output.
Six routing patterns are allowed:

1. IN > OUT
2. IN > CHAIN A > OUT
3. IN > CHAIN B > OUT
4. IN > CHAIN A > CHAIN B > OUT
5. IN > CHAIN B > CHAIN A > OUT
6. IN > > OUT
A practical example is to have an audio source, a delay and a looper.
And the question: should the delay be placed before or after the looper? Sometimes you may need the delay to be before the looper as you may want to sample the audio with the delay or sample the pure audio source and apply the delay afterwards.
This small utility module solves this issue on the fly without having to repatch anything.

INPUTS & OUTPUTS

TO CHAIN B: Connect to your Chain B input
FROM CHAIN B: Connect to your Chain B output
TO CHAIN A: Connect to your Chain A input
FROM CHAIN A: Connect to your Chain A output
INPUT: Connect to your Input Source
OUTPUT: Connect to your Output Source

ROUTING PATTERNS

There are 2 ways to address the six routing patterns:

Buttons: using the frontpanel push buttons and/or dedicated trigger inputs to latch between 2 states.
BYPASS: Chooses between Pattern 1 and any other pattern
PARALLEL: Chooses between Pattern 6 and any other pattern
ORDER: Chooses the order A before B or B before A
DUAL/SINGLE: Chooses to use a Dual (A>B or B>A) or Single chain (A or B)
CV: The dedicated CV input expects a 0 to +5v input and allows to jump to the precise routing pattern using a specific voltage interval in increments of approx. 0.83V:

Pattern 1: 0v to 0.83v
Pattern 2: 0.83v to 1.66v
Pattern 3: 1.66v to 2.5v
Pattern 4: 2.5v to 3.33V
Pattern 5: 3.33v to 4.16V
Pattern 6: 4.16v to 5V

Following the ADDAC103 T-Networks, this new module is inspired by it's simplicity. This is a 4 voice Square Oscillator with VCA, FM switch and a slew decay for the incoming Trigger IN. All voices are then sent through a Multimode Filter.

Each voice has it's own VCA input where any input is accepted (Trigger, Gate, CV) The [DECAY] controls the slew decay applied to the incoming signal, if [DECAY] is fully anti-clockwise then it works as a Mute. The [FM ON] switches activate/deactivate the FM input coming from the previous voice: Voice 1 FM comes from voice 4, voice 2 FM comes from voice 1, and so on, so you can FM all of them in a FM loop.

All 4 voices are summed and sent through a filter with controls over [CUTOFF] with an Attenuverter for the CV input and [RESO- NANCE]. Three filter outputs are provided [LOWPASS], [BANDPASS] and [HIGHPASS]

The [EXTERNAL IN] input can be routed through a jumper on the back of the module allowing the incoming signal to go to:
the filter input for processing an external audio source.
all of the 4 voices Frequency control allowing for some experi- mental CV control over pitch of all 4 voices at the same time (due to the specificities of the circuit and to keep the module at a low price these inputs are not callibrated to 1v/octave).

Notes: ***B-STOCK: Box opened, product in perfect working order***


This is the last module in Addac System's T-Networks series, a straight forward 4 voice module with frequency and decay controls for each of the voices. As the name already unveils, a noise source has been added, and 2 different circuits have been created, that explore the timbre of a t-network when used to filter noise.

There are 2 different circuits in this module, voices 1 to 3 have a pre-vca t-network filter while in voice 4 the t-networks filter applied post-vca.

At each voice input there's a switch which sets which type of input to use, this signal will be used to control an internal VCA hence why the type of setting defined here is important:
1. Trigger - Any incoming CV will be converted into a 1ms trigger as soon as it crosses it's fixed threshold.
2. Mute - This disconnects then incoming signal effectivelly muting the voice.

3. Envelopes - This can be used with CV sources as well as Gate sources and simply follows the input signal.

This incoming signal will then be processed by a slew circuit which adds a decay factor allowing the user to set the "Tail" of each voice.

Trigger mode is mostly dedicated for percussive sounds while the Envelope mode is open to any external enve- lope control and able to control noise swooshes, swirls, crackles and pops simply out of t-networks filtered noise.

Audio inputs are also welcomed to be used as a Trigger/Envelope input.

Diferences between voices:
The first 3 voices also feature a Timbre selector switch: Hat/Snare
In Snare mode all frequencies coming from the t-networks filter pass thru to the output .
In Hat mode it adds a High Pass circuit which removes the mid/bottom frequencies (characteristic of the snare strike) creating a higher spectrum output which is closer to a Hat timbre.
All of these 3 voices are also differently tuned from each other to offer more timbrical options.

Voice 4 is closer to a typical t-networks circuit but this time peculiar one where the noise is gated by the vca and then sent through the t-networks filter.

Hat and Snare are terms used very looselly here, they are timbrical references and do not in any shape or form try to effectivelly replicate the complex timbres of a real world Hat or Snare.

Notes: Another addition to ADDAC200's CV Utilities.

This module features 3 independent Attenuverters each with its input, output and 13mm knob.

Notes: Neat little modulation generator based around an external light sensor, hooked up via a patch cable. Generates two CV signals based on the light level hitting the sensor, with adjustable speed and sensitivity.

Supplier's Notes:
Another addition to ADDAC 300's Expressive Controls series.

This module converts the incoming light hitting an external light sensor into 2 Bipolar CV Streams:
Output: More light > Higher CV output
Inverted Output: More light > Lower CV output

The external sensor is enclosed in a jack socket in order to be used with any standard jack cable and be able to place it in any place outside the eurorack frame.

There are several controls to adjust the CV Output's signals:

Sensitivity:
Adjusts the Light Sensor sensitivity to Light- the higher the sensitivity, the better it responds to low light situations

Response:
3 fixed settings (medium/fast/slow) to set the slew applied to the raw signal coming from the sensor.

Gain:
Sets the gain for both outputs

Offset:
Adjusts the Offset for the main Output.

Inverted Offset:
Adjusts the Offset for the Inverted Output.

Notes: One of the most impressive granular synthesis approaches in Eurorack, combining looping and granular effects with buffer sizes up to five minutes. Hugely creative and powerful dual-module setup.

Supplier's 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 completely different parameters originating what is commonly referred 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.

ADDAC have added the possibility of long buffer sizes up to 5 minutes, allowing "softer" approaches 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 its dedicated panel, all jack inputs and outputs have its own separate panel to allow no compromise when playing it's 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.

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.

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.

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.

Notes: Inspired by Twin T-Networks circuits used in many lengendary drum machines, ADDAC system have developed a simple and straight forward 4 voice percussion module with frequency controls for each of its voices.

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.

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.

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.

Notes: A Comparator is an electronic circuit that compares two voltages and switches its output to indicate which is larger. The Comparator operates between -10 or +10V

The Output is always -10V if below Threshold and +10V if above Threshold.

A Rectifier is an electronic circuit that is used to transform AC signals to an equivalent DC signal while removing one of it's polarities, i.e. Positive rectification excludes negative signals and vice-versa.
Both sections can be used to change the shape of any waveform as well as its harmonic content.

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.

Notes: A 4 Channel VC Attenuator and Offset.

The ADDAC212 is a 4-channel VC attenuator and off-setter. It lets you deal with up to four parallel inputs as a single pack, modulating their amplitude and offset (± 10V) with the same control knobs, both with cv inputs and dedicated attenuators.

Features 4 parallel VCAs with the same amplitude and offset control knobs and cv inputs with dedicated attenuators.

Idealized to be the perfect companion for Envelope Generators, you can send 4 EGs through it and control the overall amplitude and offset of all 4 envelopes at once. This allows more control over the Envelopes when patching typical synth voices.

Notes: This is the VC Rotator, a stepped routing module for any type of signal (audio, cv, gate, trigger...)

Similar to a VC switcher but in this case there's the same number of inputs than outputs so, instead of 4 to 1 or 1 to 4, this module is always 4 to 4 but it can be patched for 2 to 2 and 3 to 3 step actions.

All four inputs get routed to the four outputs depending on the CV and Clock controls and are divided into 4 routing steps:
1. routes all inputs to the same number output: 1:1, 2:2, 3:3, 4:4
2. routes all inputs to an offset of 1: 2:1, 3:2, 4:3, 1:4
3. routes all inputs to an offset of 2: 3:1, 4:2, 1:3, 2:4
4. routes all inputs to an offset of 3: 4:1, 1:2, 2:3, 3:4

Direction determines if the clock input goes forward or backwards.
Going forward it can be set to 2-3 or 4 steps using the Rotate knob offset, going backwards always sync to 4 steps even if offseted by the Rotate knob.
For 2 & 3 step action input 1 is normalled to input 3 and input 2 is normalled to input 4.

Reset resets the internal clock to the first step.

Pendulum, external sequencing or any complex CV actions can be achieved using the CV input and dedicated attenuverter.

4 leds monitor which input is routed to output 1.

Notes: A pair of ADDAC213As acts as a simple one-cable bridge between different cases. By itself the ADDAC213As can send/receive 8 CV or audio signals between your cases, but can be expanded to bridge two cases for up to 24 signals at the same time.

Use a pair of ADDAC213As to send & receive 8 CV or audio signals between distant points in your case, between two separate cases, or between your case and a friend's case. Less clatter, less spaghetti, faster connection! There's nothing better than being able to connect that controller skiff with just one cable to your main system. At a gig, in the studio, when jamming with a friend, give yourself a gift by grabbing a pair of ADDAC213As.The modules can be installed in normal position or a 180 degree position to fit any need and any case design.

Each ADDAC213A module can be connected through a ribbon cable connection on its backside with up to two ADDAC213Bs. Each ADDAC213B module added expands the channels options of the ADDAC213A by adding 8 more channels. With two 2 ADDAC213Bs connected to each ADDAC213A module, you'll have a total of 24 channels going between your cases with a simple one-cable bridge. Between the ADDAC213A pair and the ADDAC213B, your cases never looked so elegantly connected together!

The ADDAC213As are always sold as a pair of 2 modules and an included ribbon cable.

Each module can be installed in normal position or at 180 degrees.

Comes with a 50cm ribbon cable. Custom sizes are available upon request.

Notes: The ADDAC213B is the second pair of modules from ADDAC's Eurorack Bridge system.

A pair of ADDAC213Bs can be used in standalone to send/receive 8 CV or audio signals between different points inside the same case or as an expansion to the main pair of Eurorack Bridge modules, the ADDAC213As.

Two ADDAC213B modules can be connected to each other with the use of a single ribbon cable and then used inside a case to carry signals between distant points without the need for long cables. Less clatter, less spaghetti- more space of your fingers on those knobs!

ADDAC213Bs always come in pairs. A single pair can send & receive up to 8 CV or audio signals between different points in your case at the same time. The modules can be installed in normal position or a 180 degree position to fit any need.

As an Expansion to an ADDAC213A.

Each ADDAC213B connected to the backside of an ADDAC213A adds 8 more channels to the main bridging functionality of the ADDAC213A.

Up to 2 ADDAC213B can be connected to an ADDAC213A module, expanding the bridging between two difference cases to a total of 24 channels.

If you're looking for a simple one-cable bridge between your various cases, then look no further than the ADDAC213A.

Between the ADDAC213A pair and the ADDAC213B, your cases never looked so elegantly connected together!

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.

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.

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.

Notes: The ADDAC221 is a standard midi controller that allows CV inputs, converting CV variations to MIDI Control Change Messages. This allows interaction with your favourite standalone synthesisers and softwares through simple plug-and-play midi control.

A dedicated software permits the user to store up to 9 different presets, where the CC values of each channel can be configured as wished.

This way the user can preset his favourite synths to control filters, envelopes and whatnot from CC messages coming from the module CV inputs.

Ships with 2 stereo jack to din5 midi cables.

Notes: Most recent from the ADDAC MIDI Series, the 222 converts 4 CV inputs to four distinct polyphonic MIDI NOTES streams, with up to 6 note voices per input. This allows the user to send MIDI notes to external midi devices straight from your modular: just plug it into your classic synth or your favourite virtual instruments. Combined with the ADDAC221 you can fully control any external MIDI device.

Ships with 2 TRS to MIDI type A cables (Korg, Make Noise...).

Note: All specifications and features are subject to change without previous notice.

Notes: While ADDAC were working on the new VC Stompboxes several expression pedals were tested and it became clear that most often, while playing a modular system, your hands are busy.
It's also normal to have an expression pedal lying around somewhere, so ADDAC have brought these back, cleaned up the dust and put them to good use.
This module allows the connection of any standard expression and sustain pedal.

The expression pedal action can be fine-tuned with Range and Offset knobs.
Range defines the voltage range (-10v, +10v).
Offset transposes the range by (-5v, +5v).
Two leds, plus and minus, monitor the CV Output
Positive and inverted output jacks.
The sustain pedal action will generate a gate signal on the gate output.
One led monitors this output.
The module also features a bus board +5v Adaptor, this will be able to provide +5v to any bus board.
This feature can be removed through a jumper on the back of the module.

Notes: The ADDAC302 Nchunk Control module allows you to connect a Nintendo Nunchuck controller to your modular synth, featuring a two-axis thumb joystick, a three-axis accelerometer and two trigger buttons.

The module provides CV outputs for all of the Nunchuck's parameters and special functions to remap the CV outputs. The remapping can be both continuous or step-by-step and can be accessed through either the dedicated CV inputs or the manual controls.

A specially dedicated Mix output averages between the first two CV outputs, a very useful feature for continuous control parameters.

Notes: Another addition to ADDAC300's Expressive Controls Series.

Preceded by the release of our ADDAC303 Muscle Sensing module this is the second module we make to take advantage of the physical body as a control source.

This module originated from a simple idea: using one's heart beat as a control source.

Using a clip-on sensor, that can be attached to a finger or an ear lobe, the user's heart rate will be aquired by sensing the blood flow passing under the sensor. This pulse will generate a trigger and an AD envelope.

Clip-on sensor will be provided with the module.
