Rast Sound has launched a free filter effect plugin design to add movement and character to your sounds.

Mad Filter features complex LFO motion that allows you to transition between different filter types.

Mad Filter comes with state-of-the-art drive and filter circuits, they sound warm, analog-like and rich. This character and the drive function is at the center of our plugins final sound.

You can transition between different filter types (lpass, hpass, bpass, notch) to create unique movements. Mixing filter types in such a way is only available through Mad Filter. You can click small circles on top of each knob to trigger natural, complex LFO movements and further add playful randomisation with 2 level ‘Go Mad’ button.

The plugin is free to download for Windows and Mac in VST3 and AU formats.
