Notes: Control Eurorack using your breath with this unique module from ADDAC. A melodica pipe connected to the front panel allows you to generate two independent CV signals from breath inputs. Funky.

Supplier's Notes:
This module expands ADDAC's line of expressive controls, it follows the heritage of wind/breath controllers with one major difference, the pipe has no air escape creating pressure inside the tube controlled by the user's mouth. For a seasoned woodwind or brass musicians this working principle may sound unorthodox, however this way pressure can be controlled for longer without the need to breath in or learning circular breathing techniques. It's relatively easy to control the pressure in your mouth while still breathing through the nose.

The module is provided with a standard melodica pipe which connects to an air filter (providing a receptacle for condensation to form and isolate the sensor) and lastly connects to the module frontpanel.

The signal captured by the sensor is then sent to two independent sections with exactly the same functions as seen in the signal flow diagram below.

As an example the two sections can be used with different settings to independently control the VCA and VCF of any standard analogue voice patch.

Pipe

ADDAC are using a standard Melodica pipe into an air filter that will keep condensation away from the sensor. The air filter is then connected to the frontpanel sensor input using a silicone tube.

Sensor calibration

[RESPONSE] is the main control to calibrate the pressure curve, the knob goes from exponential to logarithmic with linear at 12 o'clock. Exponential will be more reactive to high pressures, logarithmic to lower pressures.

Hold function

This feature allows to hold the current voltage value with the hold is engaged (button led on), the state can be changed either by the push button in a latching manner (push to change state) or via the gate input in a momentary manner (hold on while gate is on)

Extra Pipe

Extra Pipes are available separately.

Notes: Another really interesting physics-based module from ADDAC, the Swell models ripples in a body of water, translating the height of imaginary buoys into control voltage signals to create an organic, fluid modulation source.

Supplier's 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: Eight independent fixed-frequency filter bands combine with linear VCAs to create massive sonic potential. VCAs also double as envelope followers, with a CV output per band.

Supplier's Notes:

The ADDAC601 Analog Filterbank will have you shaping the spectrum of your sound "tout de suite".

With its 8 fixed frequencies, this very special filterbank has two additional features that you won't find anywhere else. Each of the 8 band volumes can be controlled through a linear high performance VCA, which adds great dynamics and new abilities to the art of filtering. Additionally this module also doubles as an envelope follower, with a dedicated CV output per band.

It features numerous output options: you can select between individual bands, the full processed sound, a wet/dry signal and even choose between odd or even frequencies.

Plus you can add up to two different signals, which are mixed internally by the ADDAC601 inputs.

Notes: A typically well thought-out approach to matrix mixing from ADDAC, the 814 is a stereo, expandable 6x6 design with separate control and in/out modules. Suitable for line/synth level audio or CV.

Supplier's Notes:
Introducing ADDAC's take on matrix mixers, a 6x6 stereo matrix easily expandable to larger configurations.

Matrix mixers may need some time to get used to, but they are very much self-explanatory, each knob controls the volume of a matrix point routing the respective input to the desired output. The flexibility of a matrix mixer is far superior to a standard mixer, the possibility to route any input to any single or multiple outputs allow for very complex chains, combining parallel and series processing while easily reconfigurable without any extra patching.

All Inputs Left channels are normalled to the Right Inputs.

Blank areas on the left and bottom edges of the panel allow for the user to write all the inputs and outputs sources that each channel is connected to.

Different coloured knobs for faster visual recalling: Black for A,C,E Outputs Dark Red for B,D,F Outputs Cream knobs for potential feedback diagonal: 1A, 2B, 3C, 4D, 5E, 6F.

DC coupled circuitry, can be used to mix both audio or cv signals.

Jumpers on the back of both modules allow the user to set each channel independently to Line or Synth Level, making it easier to integrate with external sources, sound processors or guitar pedals.

Internal connections

The control and input modules are connected via a large 34 wire ribbon cable, only the control module needs to be connected to the Busboard.
Extra IDC sockets are used for connecting larger configurations like 12x12 or 18x18.
Other configurations are also possible: 6x12, 12x6, 12x12, etc...
Up to 12x12 all ribbon cables are provided, for larger matrixes custom ones will be necessary, contact us directly if planning to go BIG.

Potentiometers

Although ADDAC System are using Thonk's Tall Trimmer Topper for Knobs all potentiometers used have metal shaft and are not plastic trimmer potentiometers.

Tech Specs: 25HP + 8HP (33HP total, 4.5cm deep, 140mA +12V, 140mA -12V
