Eurorack Modular (3U)

Sound Processing

Sound Processing

The sound processing category includes modules that modify incoming audio signals. It features classic components like filters, as well as resonators or ring modulators. Whether legendary designs from Cwejman, experimental circuits from Rossum, or simply good modules from Doepfer—the choice is truly extensive. The wide range of possibilities for connecting individual components—whether for audio or control signals—enables unique results when using modular systems.
