ADDAC System Dives into the Sea with New Swell Physics Eurorack Module

Forget deep space: Swell Physics takes your sonic journeys into the ocean and beyond, with an impressive set of parameters and controls

ADDAC System announces its latest innovation in Eurorack modular synthesis: the Swell Physics ADDAC508. Swell Physics follows the highly regarded ADDAC503 Marble Physics, and features a new simulation of a physical system – to start, imagine you are in a small area in the middle of the ocean.

In this imagined area, we place four equally spaced buoys – anchored to the bottom in such a system that we can control the spacing between the buoys. Now imagine that 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 System leverages Gerstner Waves for its Swell Physics module, which lends an impressive degree of sonic movement. ​ ADDAC System Founder and CEO Andre Gonçalves explains: “We use a Gerstner Wave as the motor behind the two dimensional wave generation,” he says. “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. ​ For instance, if you’ve seen any animation film or computer game with water surfaces in it most probably it features a Gerstner wave generating it.”
