Band-splitting multi-effect

Multipass is a multiband modular Snapin Host which splits the incoming signal into up to five frequency ranges which can have effects chains added to them separately. These can then be modulated extensively, using Kilohearts’ powerful modular modulation system.

Build your own Modular Multiband Effects

The open modular architecture of the Kilohearts Ecosystem gives you the freedom to design any effect you can imagine. Need a customizable multiband compressor/expander...? Build it in Multipass. Want to experiment with an effect that adds pulsing, rhythmical fluctuations and reverb to the high end whilst distorting and adding width to the mids and compressing the lows, then dynamically filtering the combined output based on the amplitude of the incoming signal...? You can build that in Multipass too.

Essential Effects Included

Multipass comes with Kilohearts Essentials, a large range of useful effects plugins. These are all available as Snapins to be combined and modulated as you desire in any of up to five frequency ranges. Premium Effects are available to buy separately to further bolster your sound design capabilities. Once a preset is saved it will be fully functional for anyone you share it with, regardless of which Snapins they own.

Mind-Blowing Modulation

A unique modular modulation section allows you to connect modulators and utilities in an infinite number of combinations for ultimate control, or ultimate chaos. Whether it’s ultra-precise envelopes and LFOs you need or wild randomisation for unpredictable chaotic mangling... you can build it with the Kilohearts Ecosystem.

"The Kilohearts ecosystem is one of the most impressive plugin bundles we know. Being big fans of Eurorack we love the modular approach to Snap Heap, Multipass and Phase Plant.
The entire suite of plugins are very well thought out and we love that the snaps are growing in number."

The Glitch Mob

"Taking multiband processing to new heights Kilohearts’ groundbreaking plugin is the ultimate effects playground. Kilohearts have developed a brilliant and technically challenging conceptual blueprint into an intoxicating reality. Multipass’ is nothing short of stupendous."
