1.8.5 Kilohearts Multipass

Kilohearts Multipass

Split signal into 5 tweakable bands.

Winner of Computer Music's 'Innovation of the Year 2016'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.

Let’s go splitsies with Kilohearts Multipass!

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 new 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 an unlimited number of effects to each band. So, pitch-shifted auto-pan with a filtered chorus delay distortion? Coming right up!

It’s been a while since I had so much fun and so many possibilities within one plugin as Multipass. I look forward to trying it out on everything! 😀

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. Parallel multiband compression, here we come!

Kilohearts Multipass Introduction Tutorial

Multipass is the most genius thing since sliced bread! Kilohearts have really outdone themselves and I’m already using it on my latest major game score. Brilliant!

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!

Modulation Station

You have to focus, Trinity

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!

Honey, I’m 4 ms late

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 they can be to make sure all modulation aligns properly and to avoid phasing issues.

Multipass’s modernized user interface, powerful features, and unlimited possibilities make this plugin a great all-in-one solution that certainly encourages creative experimentation

What’s a Snapin?

To explain, 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 we create more all the time. In fact, they also work as modular effect pieces that you can combine in our snapin host plugins, as you can see above. Nifty!

Multipass is a multiband everything plugin, and it’s extremely versatile. You can use it on anything because there are so many functions.


These are the minimum recommended system requirements for running Multipass.

2 GHz or faster
1 GB or more
Operating System
Windows (7 or newer) or Mac OS X (10.7 or newer)
A DAW supporting VST 2, AAX, or Audio Unit plugin standards.

If you have many instances of Multipass running, or use a lot of snapins at the same time in your patch the CPU usage will increase accordingly. Thus, we cannot guarantee that Multipass will work flawlessly in all use cases even if your system does meet the minimum recommended system requirements.

The versions of the plugins installed via the Slate Digital installers, like other Slate Digital products, uses the iLok licensing scheme. If you are using these versions, an iLok (USB dongle or iLok cloud) with a valid license from Slate Digital is required to use the plugins.
