Kilohearts Multipass Audio Plug-in Software

Split your signal into frequency bands for versatile processing! Kilohearts Multipass is a powerful multiband processor plug-in, and a modular Snapin host.

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.

Since Multipass is a Snapin host, Snapin effects can be purchased separately to use within Multipass, and some are available for free. All presets (factory and third-party) will be fully functional even if you do not own the effects used but you won't be able to alter the parameters for those effects you don't have licenses for. So you can share presets with all your friends and family, safe in the knowledge that they will work just the same.

Let's go splitsies!
When adding effects to a sound, it's not uncommon to want to apply these effects to just a certain part of the sound. For example, you might not want a complex chorus to affect your bass too much, or a hard distortion to totally fry your high end. Either way, multiband processing adds a dimension to effect chains that really opens up a world of options in sound design. Multipass helps you with this, allowing you to split the input sound into up to 5 easily tweakable frequency bands and applying unlimited number of effects to each band. Pitch shifted auto pan with a filtered chorus delay distortion? Coming right up!

Build your own Modular Multiband Effects
The open modular architecture of the Kilohearts Ecosystem gives you the freedom to design any effect you read more 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.

Time to phase the music:
Band splitting comes with a bit of a price. It's unavoidable (without adding latency) to mess a bit with the phase of the sound. Usually this is not a problem, but when chaining multiple multiband effects this can add up to a lot of phase distortion. In Multipass, the band splitting is only done once no matter how many effects you add, leaving the phase as minimally harmed as possible. It also sorts out dry/wet mixing of effect lanes properly without phasing where possible.

Modulation station:
While adding four filters a frequency shifter and a stereo width modifier can be interesting in itself, adding four filters with sweeping cutoff retriggered by audio threshold, a frequency shifter bound to the MIDI note and stereo width scaled by the input RMS can be... Well, probably strange. But it may be amazing, and trying it out is just a couple of clicks away. Try it!

What's a snapin?:
Well, snapins are regular old VST/AU plugins that you can use for a multitude of purposes. They come in a bunch of different flavors and Kilohearts creates more all the time. The thing is that they also work as modular effect pieces that you can combine in Kilohearts' snapin host plugins, such as Multipass!


- When you're tweaking a specific frequency band, the other bands and effects involved can sometimes make it hard to properly hear what's going on. Mute or solo effect lanes to quickly home in on what you're doing. And if you automate it, it can even be an effect in itself!
- Don't worry about latency. No matter how you route things or what effects you add, Multipass makes sure everything is as in sync as it can be to make sure all modulation aligns properly and to avoid phasing issues.
