ADDAC System Extends its line of Expressive Control Eurorack Modules with Pressure to CV
Innovative new module follows heritage of wind and breath controllers, while adding precision sensors and extensive CV control
Lisbon, Portugal, July 25, 2024 — ADDAC System announces the latest module in its growing family of expressive controls for Eurorack: the ADDAC310 Pressure to CV. Like other modules in its 300 series of expressive controllers - including the ADDAC303 muscle sensing, the ADDAC308 Light to CV and many others - the Pressure to CV offers a new means of controlling the nuances of sonic expression.
The ADDAC310 follows the heritage of traditional wind and breath controllers with one major difference: the pipe contains no means for the air to escape, creating an abundance of pressure inside the tube - which is controlled by the user’s mouth. For seasoned woodwind or brass musicians, this working principle may sound unorthodox - but using this approach, the pressure can be controlled for longer periods without the need to draw a new breath or learning circular breathing techniques.

Breathing life into a patch
While this may seem like an unconventional approach to creating and controlling sound through a Eurorack module, users will find that it is relatively easy to control the pressure in one's mouth, while still breathing through the nose.
The Pressure to CV module includes a standard melodica pipe, which connects to an air filter before ultimately connecting to the module's front panel. 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:

Once the pressure of the breath is captured at the pipe input stage, users can access either of the two 'Response' knobs to calibrate the pressure curves of the sensor. These knobs can be adjusted from exponential (fully counter-clockwise) to logarithmic (fully clockwise) or they can be set to linear in the middle at 12 o'clock. Typically, the exponential setting will be more sensitive to high pressure, while logarithmic will be more sensitive to lower pressures.
Meantime, Hold buttons at the top of the module will maintain the current voltage value when engaged (with LED on). The hold state can be changed by either pushing the button again, or by the gate input - which will hold the signal while the gate is on. These features, combined with other controls on the module, offer an unparalleled degree of expressive control in almost any Eurorack modular system.
The ADDAC310 Pressure to CV, which costs €340, is available now on the ADDAC site and at ADDAC System's network of retailers around the world. For more information, please visit https://www.addacsystem.com/.
About ADDAC System
ADDAC develops advanced instruments for sonic expression. The company started back in 2009 with an ambition to explore the potential crossover between analog synthesizers and computers. Because its first creations sparked a lot of attention, ADDAC decided to work hard and put them in customers' hands. Today our product line is focused on a new breed of hybrid synths, that make use of the best of both the digital and analog worlds. We've grown to be able to reach thousands of enthusiastic clients, friends and collaborators. Always looking into conceptualizing and developing the most exquisite instruments, we hope you're able to join and share this passion with us.
Our solutions can be found in many personal studio throughout the world, owned by musicians in several planes of stardom. We especially appreciate seeing them being used in a very wide range of musical genres.
