Malfunction circuit-bent filter

FORMAT: Audio Unit plugin for macOS 10.6.8+

This product is currently unavailable.

Malfunction is a “circuit-bent” filter - a filter with intentionally broken connections and erroneous math that produces very special, hissy and screaming distortion. To tame this dramatic effect the plugin includes a low-pass pre-filter with a booster, as well as an output gate followed by a multi-mode filter. Malfunction also has two highly versatile tempo-synchronized modulation generators routed into the circuit-bent and the output filters for intricate morphing and pulsations: they feature many different waveforms including our special “broken triangle” and “staircase”. Plus, these modulators also offer variable chaos control which gradually adds random, never-repeating accents on each individual waveform cycle.


Malfunction has an intuitive user interface built with Sinevibes trademark color-coded, animated graphics and highly legible shapes and text. Thanks to carefully tuned parameters, superb efficiency and stability, Malfunction is a deeply creative tool that is also very enjoyable day to day.
