1. EchoBoy

Soundtoys EchoBoy

Unlike vintage hardware echoes, getting perfectly timed delays with EchoBoy is simple. Just dial in a musical note value and lock it to your song’s tempo with the flip of a switch.

One of Soundtoys headline acts is EchoBoy. This is more than just your standard delay effect; EchoBoy comes with many features that you’ll find helpful throughout your music production journey.

The Soundtoys team is obsessed with vintage Analog gear, which is apparent with this VST as they have drawn inspiration from all of their favorite hardware.

Key Features:

  • Rhythm echo mode
  • Dedicated 3-band EQ
  • Diffusion, wobble, and saturation effects 


This is a fantastic plugin, and easily one of the best Soundtoys has on offer. The Rhythm Echo mode is a new and exciting way to approach delays.

This mode can have up to 16 repeats, and you can adjust the loudness for each note. The level of intricacy offered to you is unmatched, in regards to designing custom delays.

Their tempo match switch is the fastest way to go from ideas to practice. A unique feature is adding swing and feel to the delay, not something you find on a standard delay plugin.

The 3-band EQ also provides excellent control over the sound you’re designing, with decay for each band offering further control over the sound. 

2. Decapitator

Soundtoys Decapitator

Subtle to extreme hardware-modelled saturation. The secret weapon of top mix engineers. Decapitator brings the best of analog saturation to your digital studio.

Another one of Soundtoy’s flagship plugins is Decapitator. Simplistic in design, but complex behind the scenes. Soundtoys aimed to create a comfortable distortion for both subtle and destructive instances.

They achieved this by modeling the analog gear that was best able to attain the sound they wanted. Adding additional tone control and mix knob provides a convincingly analog sound with further control than previously available.  

Key Features:

  • PUNISH button!
  • 5 different analog saturation modes based on studio hardware
  • Thump and steep frequency switches
  • Saturation control with tone dial


Decapitator is an excellent emulation of analog saturation. This VST is versatile; you can add this almost anywhere in your mix.

Decapitator is excellent on vocals and keys when you want to add a bit of flavor to tracks that otherwise sound too clean.

But where this plugin shines is when you push it to its limits. With the addition of the Punish button, you can begin to dial in some punch and destruction to things like your bass and drums.

Furthermore, this VST is incredibly easy to use and will be a great addition to both beginners and experts in production. 

3. FilterFreak

Soundtoys FilterFreak

Are you searching for smooth, silky, analog filter sweeps? Or are grimy, resonant squelches more your style? Nothing adds character to a track faster than a great filter, and FilterFreak can do it all. 

Check Price On PluginBoutique Check Price On Soundtoys


FilterFreak is an essential tool for both sound design and music production. You can use FilterFeak in 2 separate forms. FilterFreak1 can be used as a simple filter or FilterFreak2 provides 2 separate analog filters for more intricate modulation.

In addition, you can use the plugin series mode for further detailed sound design options.

FilterFreak provides low-pass, high-pass, band-pass, and band-reject filters. In addition, the Tweak button allows access to the virtual filtering circuit, which opens up an abundance of further parameters to design your sound. 

Key Features:

  • Double band filter 
  • Rhythm and groove filtering tools 
  • Series or parallel filtering 


Something that is often lacking in digital synths is filtering, and FilterFreak is an excellent solution to this to bring some more life into a track. Furthermore, it has a very intricate design capability with the shape editor.

You can fully edit LFOs to your choice to have some incredibly creative sweeps and oscillations.

For sound designers and EDM producers, you will find the tweak and rhythm sections very appealing, opening up a whole new door for modulation on your tracks. FilterFreak is also excellent on drums if your drums are feeling very flat and lack punch.

It can also be a great tool to marry your drum beats together, making them feel more organic rather than disconnected. 

4. Crystallizer

Soundtoys Crystallizer

Crystallizer is an otherworldly creative effect that transforms instruments using a combination of pitch shifting and reversed echo.

Check Price On PluginBoutique Check Price On Soundtoys


Crystallizer is sold as a Granular Echo Synthesiser however it is far more than that. This plugin has an abundance of parameters ready for you to dip your toes into.

Pitch shifting, splicing, delay, and reversing are some key elements at your disposal in this synth. This VST has all you need as a sound designer regarding granulation.

In conjunction with its vast preset library, designing sounds and scapes has never been so easy. But if you want further control, The Tweak button opens up another control panel so you can dive deeper into your sound design. 

Key Features:

  • Pitch modulation 
  • Reverse switch 
  • Splice, recycle, and delay features 
  • Tweak button for further design 


I love Crystallizer! As a sound designer, this feels like an instant cheat code in designing luscious soundscapes. It is an incredibly powerful creative tool with an abundance of design possibilities.

This plugin works excellently with melodic tracks, especially for designing cascading evolving sounds.

However, it is also very interesting when added to tracks like drums to add some more variation. This works very well with EDM and DnB drums when cranking up the pitch and splice parameters, which can lead to some excellent results. 

This plugin is a no-brainer for sound designers, and would be at home in EDM and electronic music production spaces.

5. Little AlterBoy

Soundtoys Little AlterBoy

Little AlterBoy is Soundtoys’ exciting new tool for dramatic voice alteration. Get a huge range of vocal transformations from one simple plug-in.

Little AltarBoy is Soundtoy’s answer to voice pitching and manipulation. This is a very clever plugin designed to make drastic modulation to vocals which often is unachievable with stock pitch shifters.

Not only can you change the pitch, but with the format dial, you can also change the gender of the vocals.

Furthermore, you can produce a vocoder-like effect with the robot mode. This works very effectively with a MIDI controller, as MIDI can drive this VST. Alter boy also uses a tube saturation module from Decapitator.

This helps to brighten up and sharpen your vocals. 

Key Features:

  • Pitch shifter 
  • Formant (for gender modulation) 
  • Several different tuning modes 
  • Decapitators drive module 


AlterBoy is a very reliable pitch-shifting plugin and is one of the best Soundtoys plugins for vocals. It helps to remove artifacts that I’ve found problematic with some stock pitch shifters. Not only this, but AlterBoy is a fantastic creative tool.

It’s a brilliant way to change and adapt vocals to best fit the music you are working on.

Accompanying this plugin with a MIDI controller makes designing vocal sections incredibly satisfying. The drive parameter is also an excellent addition, making this a one-stop shop for vocal shifting and processing. 

6. PrimalTap

Soundtoys PrimalTap

PrimalTap is an emulation and re-imagining of the unique sound and features of the Prime Time delay, a classic digital delay with some powerful performance and sound design capabilities.

Check Price On PluginBoutique Check Price On Soundtoys


At its core, PrimalTap is a delay plugin. However, its many features have made it more of a sound design tool.

One of the most exciting decisions made by the production team was the emulation of the 80’s style Multiply switch. This means every time you double delay, the sound quality is reduced.

This may seem like an odd choice for a VST made in the current generation. However, it leads to some interesting sound design moments when automating between the modes.

Another feature of this plugin is the freeze button. This stops and loops the track and, when accompanied by automating the plugin’s parameters, leads to the design of some incredible soundscape design options.

Key Features:

  • Freeze button 
  • Tweak for additional control 
  • Multiply knob 
  • LFO rate and depth parameters 


PrimalTap works well as a standard delay plugin. However, this is not why I recommend this product — I recommend it for anyone looking to get weird and experimental with their sound design. Think pitched warps, modulating sequences and otherworldly, ethereal effects.

When automating the parameters on this plugin, you can create some very interesting bouncing delay effects.

Modulating the multiply feature adds a Lofi-like quality to the sound when cranking it up to the max. With this plugin, you can create some very similar sounds to Crystallizer in terms of soundscapes. 

7. Devil-Loc Deluxe

Soundtoys Devil-Loc Deluxe

The Devil-Loc Deluxe plugin version adds a “Darkness” control for tone, switchable slow or fast release times, and a mix knob so you can mix your dry signal back in right on the front panel.

Check Price On PluginBoutique Check Price On Soundtoys


Devil-Loc is an audio processing tool that you can use to tighten up and/or add some crunch to your tracks. Adding both compression and distortion to the desired track, the main purpose of this VST is for massive drum production.

However, that’s not to say you can’t use this plugin on other tracks as it’s more than suitable for adding some darkness and grit to melodic loops.

Especially when accompanied by the darkness high-cut, this can be an excellent use of the plugin if you want a warmer tone. 

Key Features:

  • Darkness (which is a high-cut filter)
  • Compressor release 
  • Crush compression 
  • Crunch distortion effect 
  • Mix knob 


One of the more basic VST plugins on my list, but this is a very useful music production tool that can be utilized across multiple genres. I will say that this plugin is certainly most at home when added to drums.

Devil-Loc helps to add that “oomph” EDM producers are looking for in their productions. Its simple controls make it a no-brainer for both professionals and beginners alike. 


What’s The Difference Between VST2 And VST3?

The main difference is CPU usage. VST3 is more optimized in the sense that the plugin is only active with the presence of an audio signal. Whereas VST2 is using CPU all of the time. 

Are Soundtoys Plugins VST2 or VST3?

Currently, Soundtoys are VST2 plugins. However, they are currently working on developing a VST3 release. 

Do Soundtoys Work With Reaper?

Yes, Soundtoys work within reaper. 

Do Soundtoys Work With Mac M1?

Yes, Soundtoys work on the M1.
