Make Noise Bruxa
Echoverb signal processor — multi-tap delay with complex feedback filtering
18 HP Eurorack module
Bruxa is a collaboration between Make Noise and Alessandro Cortini, evolving the prototype circuits that became Strega into a Eurorack-format Time/Filter Experiment. It features a multi-tap delay line with over a dozen unique feedback paths and multiple filters within those feedback paths, allowing accumulation of noise, saturation, and signal degradation. The all-analog dry signal path blends with a digital/analog hybrid processor via the Blend control, while two CV outputs derived from the internal feedback enable self-patching for evolving, unpredictable textures.
