The DRIVE/DISTORTION dial is the primary control for the plugin, adding warm, rich and sweet tones to your music. FREQUENCY, TYPE and RESONANCE knobs allow you to transition between different filter types, including low-pass, high-pass, bypass and notch to create unique movements. Trigger natural, complex LFO movements, and playful randomisation using the 2 level ‘Go Mad’ button.

Mad Filter is available in AU and VST3 formats, for 64-bit Mac and Windows computers, with at least 4GB of RAM. Currently there’s no support for AAX.
