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: 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: This is a new revision of one of ADDAC's first modules, back from 2010.

Now more compact in 6hp and with an Offset CV input.

The incoming signal amplitude is controlled by a [GAIN] attenuverter circuit allowing to attenuate the signal as well as invert its phase.
A back jumper can set the maximum gain amount to either x1 (unity gain) or x10. DIY modifications can be made by changing its resistors.
After the Gain an offset can be added to the signal, displacing the signal up or down (-5V to +5V) this can be adjusted using the [OFFSET] knob and CV input

When using no input using the [OFFSET] knob and CV input will generate an output between -5V and +5V.

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: 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: ADDAC System's 1/4 to 1/8 inch adapter allow you to connect one 1/4 inch jacks to an 1/8 inch one right in from your rack- now you can leave all those cable adapters behind.

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: 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!

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: 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: 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: ADDAC402B MIDI Expansion allows full I/O Midi control of ADDAC402 plus access to a powerfull midi interface, with:

Midi Sync:
Allows the module to synchronize with any external MIDI device’s Clock, including transport messages like play, stop and continue.

CV to MIDI:
5 CV inputs (Fills 1 to 4 and Assign) to MIDI Notes and/or CC messages, the Note and CC number can be independently configured via the Configuration Menu.
These CV inputs can be sent on independent MIDI Channels, for ex: Fills 1 to 4 on MIDI Channel 1 and Assign on MIDI Channel 2.

MIDI Controller:
All panel controls (9 knobs, 4 toggle switches and 11 push buttons) can be sent to MIDI Out as CC controls as any standard MIDI controller. The individual CC numbers can be configured through the Configuration Menu.

MIDI to Gate:
All 4 Gate outputs can be controlled/sequenced from an external MIDI device.
For ex: we can configure Gate 1 to be responsive to CC 1, Gate 2 to CC 2 and so on. Everytime CC 1 gets a value of 127 Gate 1 will be turned ON, if it gets a 0 value Gate 1 will be turned OFF.

MIDI Control:
All panel controls (9 knobs, 4 toggle switches and 11 push buttons) can be controlled/sequenced from MIDI CC controls. This allow full automation of the module via MIDI
The individual CC numbers can be configured through the Configuration Menu and includes a midi learn feature for easier configuration.
Also controllable via MIDI is the change of Presets and Modes.

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).
