Free Ableton Live 12 Max for Live Device: Square4Filter Riddim Comb Filter (B.S Audio Tools)

Overview

B.S Audio Tools offers B.S Square4Filter, a Max for Live dual comb filter designed to give bass sounds the metallic square4 character heard in riddim music. It has time and offset controls for the comb filters, a crossover that keeps the sub clean, and asymmetric distortion for extra crunch.

The device requires Ableton Live 12 Suite or Standard with a Max for Live license and is not a VST plugin. It is pay-what-you-want on Gumroad with a $0 minimum, and the page suggests stacking several instances and mapping their time controls to one macro.
