Kilohearts offers Multipass for $29

Kilohearts are one of the most forward-thinking audio software developers at this time and have invented an incredible modular ecosystem to allow you to build infinite new effects and synths. Multipass is the effects host that splits your signal into separate frequency bands to be processed by separate effects chains using any Snapins you own and it is now reduced by over 70% to just $29.

Multipass is a multiband effect plugin with many uses. At the heart of the plugin is a band splitter which splits the audio into several different frequency bands which can be processed independently. Multipass delegates the actual processing of the bands to other single-purpose effect plugins known as snapins. Snapins come in many different flavors, and implements many classic effects like distortion or chorus as well as more unusual ones like formant filtering and frequency shifting.

Any factory presets and other presets you can get hold of for Multipass will work even if you don’t own the FX Snapins used in them. Making this a very flexible tool to have.
