Soundtoys Crystallizer

Inspired by Crystal Echoes in the Eventide H3000

Soundtoys Crystallizer is seriously cool! Can you imagine combining pitch shifting and reversed echo to completely transform instruments? Based on the Eventide H3000’s “Reverse Shift” algorithm, Crystallizer gives you granular echo slicing, old-school pitch shifting, and so many other inspiring and powerful features packed into one tool!


Use it to create synth-like textures from simple acoustic guitar rhythms, lush detuned echos, or completely psychedelic pitch-shifted reverse echo effects. Great for drums, guitar, bass, sound design, electronic music, and just about anything else – Crystallizer is a truly unique and creative effects processor.

If you listened to the radio in the late 80s, you’ve heard the Crystal Echoes effect from the Eventide H3000 effects processor. The sound is absolutely unmistakable and has been used on countless records to transform simple chords into epic soundscapes. Once musicians and engineers got their hands on this unique technique and realized how it instantly turned minimal guitar lines into shimmering symphonic textures, there was no going back. You can hear it on hundreds of records—from 80s anthems to ambient compositions, to modern indie rock and chillwave. And now you can have it, too.

Getting the Glitch Right

Crystal Method

Because Soundtoys’ founders actually designed algorithms for the original H3000, you can be sure they didn’t rest until they recreated its icy tones flawlessly. One of the key elements of the Crystallizer sound is its old-school pitch shifting. Modern pitch shifters (like Soundtoys Little AlterBoy for example) use sophisticated mathematical algorithms to transform music and vocals as naturally as possible. The original old-school devices (like Eventide’s classic H910 Harmonizer) used a simpler resample and crossfade technique that introduced audible artifacts in the pitch-shifted audio. This retro technique adds a glitchy character to the sound that is an essential part of Crystallizer’s 80s-futuristic charm.

Retro Shifter

Old school pitch-shifting just like, uh, the old school. Modern pitch-shifters use sophisticated mathematical algorithms to transform music and vocals as naturally as possible (like Soundtoys PurePitch and SPEED products). The original old-school devices (like Eventide’s classic H910 Harmonizer) used a resample and cross-fade technique that introduced audible ‘glitches’ in the pitch-shifted audio. The glitch is good. Well, in this case, it is. That’s a big part of the sound. A sound we’ve all heard countless times, on tons of hit songs. So dig into the past and enjoy the true retro sound.

Upping the Ante

Once Soundtoys nailed the sound of the original effect, they didn’t stop there. Then, they improved it by adding MIDI sync and automation to give you precise creative control. In addition, the built-in Gate and Duck feature adds a new level of dynamic control over triggering echos, helping you keep this sometimes wild effect in check. You can also shape the sound with low- and high-cut filters to create bright shimmery blooms or dark, rich beds of sound. In short, this classic effect is brought up to date with all the convenience and tweakability of a Soundtoys plug-in.

Instant Inspiration

Does “granular echo synthesizer” sound a bit hard to get your head around? Don’t worry. Soundtoys included over 200 ready-made presets that you can explore, organized into categories that make finding the perfect starting point for your tracks simple. Also, you get everything from the subtle to the all-out psychedelic, so don’t be afraid to experiment! When you’re ready to go deeper, you’ll find plenty of tweakability and control for making your own signature presets.

Soundtoys Crystallizer Highlights

  • Recreate the classic crystalline sounds of the Eventide H3000
  • Turn simple melodies and chords into shimmering, textured soundscapes
  • Create rich, evolving effects with reverse echos and pitch shifting
  • Lock the effect on your project’s tempo and even add custom automation
  • Transform guitar, bass, drums, or loops into something completely new
  • An amazing tool for creative sound designers

Crystallizer’s unique sound is magical. No other effects device sounds anything like it. It can turn a guitar (or any instrument) into a symphony or a room full of whispering voices. It will open your mind to whole new world of creative possibilities.

We first found out about Soundtoys when we were mixing our record ODD BLOOD. Since then we’ve been hooked on them. The Crystallizer and EchoBoy are in constant use, I’m literally obsessed!

32-Bit Plug-in Support

With the release of 5.3.2, we have officially discontinued support for 32-bit plug-ins. With macOS Catalina requiring all applications to be 64-bit, and with the vast majority of our PC customers using 64-bit plug-ins, we decided it was the right time to end 32-bit support. Our most recent 32-bit installers are available to download below.

5.3.1 Update

October 30, 2019

  • Fixed a bug in Little AlterBoy that could cause left and right channels to move slightly out of sync when used on a mono track in DAWs like Ableton and Cubase that process mono tracks in stereo.**
  • Fixed a similar left/right sync bug that could affect PrimalTap in “Freeze” mode.**
  • Improved parameter mapping for Resonance parameter in FilterFreak and PhaseMistress. This may very slightly change the sound of sessions that use automation on this parameter. If no automation is used on this parameter then all sessions should recall perfectly.
  • Smoothed out choppy animation on certain Retina displays.
  • Repaired window scaling problems in Windows on high DPI monitors, especially in Ableton and Studio One
  • Added MIDI triggering to PhaseMistress and EffectRack AAX.
  • Installer icons on Mac and PC should now show up more easily on a black background.

** These changes will affect the sound of audio in some sessions. You may want to bounce or freeze tracks if you want to keep the out-of-sync or phasey sound that may have occurred in previous versions.

Soundtoys 5.3.1: Our Final 32-bit Release

We’re happy to announce that Soundtoys 5.3.1 is now available. This update includes an important improvement to Little AlterBoy and PrimalTap and a number of other bug fixes.

Soundtoys 5.3.1 will be our final patch before we add support for MacOS Catalina, which will require us to drop 32-bit plug-in support. This will be our final 32-bit compatible release for both MacOS and Windows. Visit our Download Page to get the latest installers.

Little AlterBoy and PrimalTap Sync Fix

When using Little AlterBoy on a mono track with a stereo output, sometimes it was possible for the left and right channels to shift out of sync. This could add an unwanted “phasey” sound to the vocal, or create a slight difference in the sound of the left and right channels. This bug could also affect PrimalTap’s Freeze mode. Soundtoys 5.3.1 fixes this issue.

NOTE: this fix may change the sound of some audio tracks that use Little AlterBoy and PrimalTap (in freeze mode). We think this change is for the better! However, if you think the out-of-sync sound is an important part of some of your tracks, we recommend you bounce or freeze those tracks to preserve the exact sound they have today.

MacOS Catalina Support Coming Soon

If you’re a MacOS user, you’ve probably gotten word that many DAWs and plug-ins, including Soundtoys, do not yet support MacOS Catalina. Unlike previous releases of MacOS, Catalina introduces new security safeguards and ends support for 32-bit applications and plug-ins, creating a significant challenge for plug-in developers. We’re hard at work updating and testing our products, and we will have an update soon.

What’s new in v5.3

macOS and PC:

  • Plug-in activation window now includes support for Activation Codes, which will be distributed to customers who purchase a new product (not an upgrade) from our web store, and will allow those licenses to be activated without an iLok account (optional).
  • Little Plate is now included in the 5.3 license group for new Soundtoys 5 customers.


  • macOS Mojave is now officially supported.
  • Graphics issue that was causing several components of the Soundtoys graphical user interfaces to display incorrectly on macOS Mojave has been resolved.

What’s New in v5.2.3

  • Fixed sluggish animation of tweak drawers on high DPI monitors on Mac
  • Fixed rhythm editor to allow for creation of multi-bar rhythms
  • Fixed “update nesting too deep” alert
  • Added support for MIDI triggering to AAX versions of FilterFreak and PrimalTap
  • Fixed CPU spiking in certain instances
  • Fixed AudioSuite support for different stem formats (mono-mono, mono-stereo, stereo-stereo) for Tremolator, Decapitator, Devil-Loc Deluxe, FilterFreak 1 & 2, Little Radiator, Radiator, and Sie-Q
  • Fixed occasional crash when rendering in Reaper on Windows
  • Fixed preset sorting in macOS High Sierra
  • Audio Units plug-ins will now scan correctly without requiring a restart in macOS High Sierra

  • Fixed session recall in AU Lab
  • Fixed balance offset in in PanMan Random & Triggered modes
  • Updated VST plug-in names to make them consistent with AU and AAX versions when displayed in DAWs. *This included Little Plate, Little AlterBoy, Little Radiator, Little PrimalTap, Little MicroShift, EchoBoy Jr., and Sie-Q.

What’s new in 5.2:

  • EchoBoy Jr. is now available in Soundtoys 5 and Effect Rack
  • EchoBoy Jr. is now included with individual EchoBoy 5 licenses and installers
  • Some Effect Rack presets now include EchoBoy Jr.

What’s new in 5.1

Sie-Q was added to the lineup.

What’s new in 5.02


  • Plug-ins with the Analog Mode option now have a new “Op Amp” style to replace the Version 4 “Digital” style that was removed. In the previous version 5 release sessions using “Digital” defaulted to “Clean”. They now default to “Op Amp”. This will address the sound differences that some customers heard when recalling old sessions.
  • PrimalTap has a new Auto Gain switch added to the Tweak menu. When enabled, the output will automatically be lowered proportionally as the input gain is raised. This is the new default behavior for PrimalTap. Old sessions and user presets will open with Auto Gain set to “Off.”
  • Preset names, when edited, now display in italics to indicate an edited state


  • Preset names are now displayed correctly when sessions that were last saved with V4 are recalled (instead of reading “Default”).
  • Fixed an issue in PrimalTap where the Rolloff feature was not filtering the feedback loop as intended. (Note: this update will change the sound of some presets and sessions but is the correct and intended sound and behavior of PrimalTap).
  • Fixed an issue where Devil-Loc and Devil-Loc Deluxe knobs could jump to minimum or maximum when clicked in a certain area.
  • Fixed a problem where the delayed signal in EchoBoy might drop out under certain conditions.
  • PhaseMistress default settings will now sound identical to the default preset.
  • Preset names are now pre-populated when using the Save As… option.
  • Resolved a Windows problem where alerts could be hidden behind other windows.
  • Fixed issues that would cause the compare light to come on unnecessarily with certain plugins and presets.

New in Soundtoys 5:

  • Effect Rack, PrimalTap, and Little AlterBoy plug-ins
  • New authorization options
  • Workflow enhancements
